Microorganisms —A Journal and a Unifying Concept for the Science of Microbiology

The MDPI journal Microorganisms is still very young, having been launched in 2013, but the concept of the microorganism has been in use for at least a century as a unifying principle for the discipline of microbiology, which was cemented firmly by the intellectual work of Roger Stanier and colleagues in their Microbial World and other general microbiology textbooks and related articles from the 1950s to the 1970s [ 1 , 2 ]. Merging the idea of the microscopic and the very small with the older idea of an organism as a living entity or cell, the concept of a microorganism enabled a real appreciation of the microbial world as one that is amenable to study using similar tools and approaches even though representing distinctly different types of reproductive units and cell organizations. In the late 20th century following the work of Carl Woese and other molecular evolutionists, biologists came to appreciate the commonality among all organisms, all being comprised of cells that bear a remarkable similarity to one another and that share a common evolutionary ancestry, and consequently with major features of a largely shared genetic code and molecular biology. In this sense microbiology and biology as a whole became unified as they never had been before.

Though molecular sequencing of genomes and metagenomes has revealed immense diversity within the category microorganisms, now known to represent three distinct domains of life, Bacteria, Archaea and Eucarya, and perhaps hiding even more undiscovered types including a potential fourth domain according to recent suggestions [ 3 , 4 ], considering them together has scientific advantages. These include the nature of the associations and symbioses among members, the effects of scale on processes such as nutrition, the application of similar metagenomic methods to study of their diversity and ecology, the insights of a comparative approach to their genomics and potential evolutionary relationships, and analogies in some of their growth habits and strategies such as the mycelial habit of both actinobacteria and mycelial fungi [ 5 ]. When we consider a natural community, all three domains of cellular life often live together, and together with their respective viruses. Thus, methods first applied to bacteria and archaea for direct characterization of natural communities are increasingly being applied also to uncultured eukaryotes [ 6 , 7 ] and viruses [ 8 ] and even the attached viruses of uncultured eukaryotes [ 7 ] in such communities. When we talk about a microbial community, it is a community of microorganisms in the widest sense we must study, complete with bacteria, archaea, fungi, algae or protist varieties of eukaryotes, and all their accompanying viruses. In this spirit, uncultured microorganisms in different domains including the eukaryotes are increasingly studied within the same project from a particular habitat [ 9 , 10 ]. And ideally for a complete understanding we should aim at the culture of many cellular microorganisms, as well as retrieving genes of yet-to-be-cultured species from the environmental metagenome [ 11 ]. The recently proposed concept of “culturomics” [ 12 ] augmenting metagenomics for the bacterial gut microbiome [ 13 ] should be applied as much as is feasible to all cellular domains of microorganisms. In any case there is considerable potential overlap between microbial concepts [ 14 ]. Sizes of viruses and their genomes can overlap with those of bacterial cells, and some bacteria and bacterial genomes can be as large as unicellular eukaryotes [ 15 ]. Indeed, some of the smallest unicellular eukaryotes can be as small as many bacteria [ 16 , 17 ]. The giant mimivirus and similar dsDNA viruses, such as “mamavirus” and pandoravirus, though still dependent on host amoebae, may have genomes as large as some small bacteria or even (in the case of pandoraviruses) small parasitic eukaryotes [ 4 , 18 , 19 , 20 ]. They can have many genes for molecular biology processes such as protein translation normally possessed only by independently replicating cells; their genes may even bear phylogenetic relationship to ancient ancestors of eukaryotes [ 18 ] or to an ancestral fourth domain of life [ 21 ]. Such viruses may even have their own “virophage” parasitic satellites, stretching our definition of microorganisms even further [ 22 ]. The concept of virus may have to also widen to emphasize less their particulate virion phase and more their “virus factory” cellular phase of replication as the genuine organismal one [ 23 ]. Separation of microbiologists into distinct disciplinary camps to study microorganisms may have some advantages of specialization but also disadvantages of lack of comparative insight accompanying breadth of vision of more than one class of microorganism. Such insight can even change definitions of what comprises living organisms [ 24 ].

With the discovery of proteins such as FtsZ in bacteria of the same general family as eukaryotic tubulins of the cytoskeleton, only one example of many eukaryote homolog cytoskeletal proteins in bacteria [ 25 ], and even microtubule-forming proteins much closer to eukaryotic tubulins in some bacterial divisions [ 26 , 27 ], and of the ESCRT (endosomal sorting complex required for transport) III-like proteins homologous to those used in late stages of eukaryotic endocytosis used for cell division in domain Archaea in place of the FtsZ-dependent bacterial system [ 28 ], the boundaries in cell biology of distinct types of microorganism such as eukaryotes, bacteria and archaea become blurred. Similarities are such between archaeal and eukaryote cell biology and gene sequences that it is now plausible that a common ancestor of archaea and eukaryotes or even a member of an ancient archaeal lineage may have been the proto-eukaryote [ 29 , 30 , 31 ]. Additionally, a central tenet of fusion or symbiotic hypotheses for eukaryote origins is the apparent (though somewhat controversial) chimeric nature of eukaryote genomes regarding domain affinities of many genes [ 32 , 33 , 34 , 35 , 36 ], while apparent (and again controversial) widespread horizontal gene transfer (HGT) challenges the “vertical” tree concept for microbial phylogenies [ 29 , 37 , 38 , 39 , 40 ]. Synthesis of secondary metabolites such as polyketide antibiotics and anti-cancer compounds in fungi follows similar pathways to synthesis of polyketides in actinobacteria and ancient gene transfer between these distinct phyla in two domains may account for this [ 41 ]. Though domain distinctions remain workable [ 42 , 43 ], even in face of apparent substantial past HGT exchanges between domains, our understanding of each domain is only enhanced by what we learn of the others—understanding one microbe helps the understanding of another regardless of type.

As indicated by recent advances in understanding the phage resistance system of CRISPR-Cas [ 44 , 45 , 46 ] and the role of viruses of microorganisms in natural ecosystems and population microbiology at a global scale [ 47 , 48 , 49 ], understanding bacteria, archaea, and eukaryote microorganisms including their genomes and their ecology also needs understanding of their viruses and interactions with them at a molecular level. Such a lesson was of course latent in the initial early discovery of lysogeny in bacteria. Understanding eukaryote and other domain evolution requires an understanding of bacterial and archaeal genes and phylogeny as well as potential viral contributions to ancient molecular biology [ 50 ]. No microorganism can now be considered irrelevant to another no matter what the distance of their relationship. In addition, such insight may have quite innovative biotechnology implications as in genome engineering systems based on CRISPR/Cas [ 51 ].

Narrow specialization can open up to a wider vision, to the benefit of the individual problem areas as well as the enrichment of a broad biology of the very small, and indeed, biology of all organisms in the tree or net of life. “Microorganisms” is perhaps the umbrella for unicellular and sub-cellular life least subject to theoretical assumptions or controversies regarding phylogenetic relationships, the exact boundaries of Domains, and trees vs. networks, since criteria for inclusion does not depend on our view of these relationships—it therefore opens vistas to new insights even about such relationships.

The topics recently published in Microorganisms and now open and planned for submission soon reflect this broad vision at a high scientific level. We started with a mix of specialized vs. wide topics of Biology of Dinoflagellates: Advances in the Last 25 Years (1987–2012), including a review by that major pioneer of bioluminescence research and (via luciferase research) a pioneer also of a new field of bacterial quorum sensing, J. Woodland Hastings of Harvard University, and Advances and New Perspectives in Microbial Research, including a perceptive and useful critique of phage electron microscopy by Hans-W Ackermann of Laval University in Canada, and other excellent articles ranging from antibiotics from seaweed to probiotics to fungal mycotoxins in cereals to new “big data” bioinformatics analysis software to multi-resistant Gram-negative bacteria in a hospital ward to production methods for vaccinia virus in biotechnology. This issue is a very good example of the how the aims of this journal can appear in practice.

Our new topics still open for submissions include: Host-Gut Microbiota Metabolic Interactions ( http://www.mdpi.com/journal/microorganisms/special_issues/gut_microbiota_metabolic_interactions ), Microbial Activity in Food ( http://www.mdpi.com/journal/microorganisms/special_issues/microbial_activity_food ), Extremophiles ( http://www.mdpi.com/journal/microorganisms/special_issues/_extremophiles ), and Microbial C1 Metabolism ( http://www.mdpi.com/journal/microorganisms/special_issues/microbial-C1 ) and we have more exciting and diverse topics in the planning process. We have some excellent guest editors for these special issues, including for Extremophiles, Ricardo Amils of the Severo Ochoa Centre for Molecular Biology and the NASA-affiliated Centro de Astrobiología (INTA-CSIC) in Spain, and for Microbial C1 Metabolism, Ludmila Chistoserdova and Marina G. Kalyuzhnaya of the University of Washington, Seattle, USA, internationally renowned for their studies on bacterial methane utilization and its evolution and ecology. A Special Issue on “Diversity and Dynamics of Marine Microbial Communities” ( http://www.mdpi.com/journal/microorganisms/special_issues/microbial_marine ) is to be edited by Professor Dr. Johannes T. Imhoff , who leads the research unit on Marine Microbial Resources at IFM-GEOMAR Helmholtz Centre for Ocean Research in Kiel, Germany.

We can see by the breadth of topics that our Special Issues cover diverse areas of contemporary fundamental and applied fields dealing with microorganisms. We encourage researchers and thinkers in the science of microorganisms to submit to these and future special issues of Microorganisms most relevant to their area of expertise. Microorganisms in 2015 and beyond—an exciting prospect for communicating the science of all of microbial life!

Self-dyeing vegan leather made by genetically engineered bacteria

• No comments

Genetically engineered bacteria have been designed to produce self-dyeing, vegan, plastic-free leather. The work, carried out by UK-based researchers, could offer a more sustainable alternative to traditional leather and the associated chemical dyeing processes.

‘By 2050, after food and construction, materials for textiles and fabrics will be the third biggest polluter in the world – fashion and textiles already contribute more to carbon emissions than all of aviation and shipping combined,’ explains Tom Ellis , a synthetic biologist at Imperial College London who led the project. ‘In terms of carbon use, by far the worst material used in the fashion industry, is leather – the amount of land use and CO 2 and methane emissions associated with farming cows and then producing leather is crazy.’

‘Then on top of that, dying leather a different colour and cleaning it in a way that it becomes the material you want is also terrible,’ he adds. ‘The tanning process uses chromium and to get that black colour – the most popular colour for leather – you have to use azo dyes and that creates a huge amount of wastewater and chemical residue.’

To find a solution, the researchers turned to bacterial cellulose, a natural biomaterial that has been considered as an alternative to leather for over a decade. The Imperial team’s unique approach involved genetically engineering Komagataeibacter rhaeticus ( K. rhaeticus ) bacteria to express tyrosinase-related protein 1 – a gene associated with the production of the melanin pigment eumelanin. This produced a bacterial strain that grows self-pigmenting bacterial cellulose.

‘Nature tells us that if you make a pigmented molecule in the same place at the same time as when you are making a material, those pigment molecules get sucked up and are incorporated as part of the material,’ Ellis says. ‘So why can’t we just put the DNA that encodes the enzymes that make a pigment into the same cells that are making the material through genetic engineering?’

To demonstrate that eumelanin production could effectively pigment the cellulose produced by the genetically modified K. rhaeticus, the researchers first grew the bacteria under normal growth conditions for two weeks to produce a cellulose mesh known as a pellicle. They then removed the spent culture media and replaced it with a neutral buffer solution with the reagents required for eumelanin synthesis. After one day of incubation in the development buffer, the cellulose pellicle had turned completely black.

This shoe upper was made by wrapping the treated bacterial cellulose around a foot-shaped mould

The team produced a shoe upper by soaking the material in a glycerol solution to give it the required flexibility, before wrapping it around a foot-shaped mould and allowing it to dry. They also created a wallet prototype from two pressed and dried melanated bacterial cellulose sheets.

‘What was really cool was the colour just doesn’t fade – you can put water on it, scrape it - it’s much more colourfast than we thought we would get,’ Ellis says, adding that the process could, in theory, be adapted to have bacteria grow materials in various vibrant colours and patterns.

‘What we would like to do next is crosslinking – that’s what really makes leather have this nice feel and the ability for it to last 20 years. Crosslinking is normally done by chromium and other very harsh methods so it’d be really nice to find a biological solution to that,’ he adds.

The researchers note that as high yields of the material can be produced from simple static growth cultures, the method should be ‘very amenable to scale-up’.

‘This work is an elegant demonstration of the power of biofabrication and genetic tool kits to map nature’s strategies to develop advanced materials,’ says Theanne Schiros , who works as a materials scientist at both the Fashion Institute of Technology at the State University of New York and Columbia University, both US. ‘It provides important context for exciting opportunities to expand the functionality of emerging biomaterials and future textiles,’ she adds.

Using pulp and paper waste to scrub carbon from emissions

Researchers at McGill University have come up with an innovative approach to improve the energy efficiency of carbon conversion, using waste material from pulp and paper production.

The technique they've pioneered using the Canadian Light Source at the University of Saskatchewan not only reduces the energy required to convert carbon into useful products, but also reduces overall waste in the environment.

"We are one of the first groups to combine biomass recycling or utilization with CO 2 capture," said Ali Seifitokaldani, Assistant Professor in the Department of Chemical Engineering and Canada Research Chair (Tier II) in Electrocatalysis for Renewable Energy Production and Conversion. The research team, from McGill's Electrocatalysis Lab, published their findings in the journal RSC Sustainability .

Capturing carbon emissions is one of the most exciting emerging tools to fight climate change. The biggest challenge is figuring out what to do with the carbon once the emissions have been removed, especially since capturing CO 2 can be expensive. The next hurdle is that transforming CO 2 into useful products takes energy. Researchers want to make the conversion process as efficient and profitable as possible.

3. problems students are facing at public k-12 schools.

We asked teachers about how students are doing at their school. Overall, many teachers hold negative views about students’ academic performance and behavior.

• 48% say the academic performance of most students at their school is fair or poor; a third say it’s good and only 17% say it’s excellent or very good.
• 49% say students’ behavior at their school is fair or poor; 35% say it’s good and 13% rate it as excellent or very good.

Teachers in elementary, middle and high schools give similar answers when asked about students’ academic performance. But when it comes to students’ behavior, elementary and middle school teachers are more likely than high school teachers to say it’s fair or poor (51% and 54%, respectively, vs. 43%).

Teachers from high-poverty schools are more likely than those in medium- and low-poverty schools to say the academic performance and behavior of most students at their school are fair or poor.

The differences between high- and low-poverty schools are particularly striking. Most teachers from high-poverty schools say the academic performance (73%) and behavior (64%) of most students at their school are fair or poor. Much smaller shares of teachers from low-poverty schools say the same (27% for academic performance and 37% for behavior).

In turn, teachers from low-poverty schools are far more likely than those from high-poverty schools to say the academic performance and behavior of most students at their school are excellent or very good.

Lasting impact of the COVID-19 pandemic

Among those who have been teaching for at least a year, about eight-in-ten teachers say the lasting impact of the pandemic on students’ behavior, academic performance and emotional well-being has been very or somewhat negative. This includes about a third or more saying that the lasting impact has been very negative in each area.

Shares ranging from 11% to 15% of teachers say the pandemic has had no lasting impact on these aspects of students’ lives, or that the impact has been neither positive nor negative. Only about 5% say that the pandemic has had a positive lasting impact on these things.

A smaller majority of teachers (55%) say the pandemic has had a negative impact on the way parents interact with teachers, with 18% saying its lasting impact has been very negative.

These results are mostly consistent across teachers of different grade levels and school poverty levels.

Major problems at school

When we asked teachers about a range of problems that may affect students who attend their school, the following issues top the list:

• Poverty (53% say this is a major problem at their school)
• Chronic absenteeism – that is, students missing a substantial number of school days (49%)
• Anxiety and depression (48%)

One-in-five say bullying is a major problem among students at their school. Smaller shares of teachers point to drug use (14%), school fights (12%), alcohol use (4%) and gangs (3%).

Differences by school level

Similar shares of teachers across grade levels say poverty is a major problem at their school, but other problems are more common in middle or high schools:

• 61% of high school teachers say chronic absenteeism is a major problem at their school, compared with 43% of elementary school teachers and 46% of middle school teachers.
• 69% of high school teachers and 57% of middle school teachers say anxiety and depression are a major problem, compared with 29% of elementary school teachers.
• 34% of middle school teachers say bullying is a major problem, compared with 13% of elementary school teachers and 21% of high school teachers.

Not surprisingly, drug use, school fights, alcohol use and gangs are more likely to be viewed as major problems by secondary school teachers than by those teaching in elementary schools.

Differences by poverty level

Teachers’ views on problems students face at their school also vary by school poverty level.

Majorities of teachers in high- and medium-poverty schools say chronic absenteeism is a major problem where they teach (66% and 58%, respectively). A much smaller share of teachers in low-poverty schools say this (34%).

Bullying, school fights and gangs are viewed as major problems by larger shares of teachers in high-poverty schools than in medium- and low-poverty schools.

When it comes to anxiety and depression, a slightly larger share of teachers in low-poverty schools (51%) than in high-poverty schools (44%) say these are a major problem among students where they teach.  

Discipline practices

About two-thirds of teachers (66%) say that the current discipline practices at their school are very or somewhat mild – including 27% who say they’re very mild. Only 2% say the discipline practices at their school are very or somewhat harsh, while 31% say they are neither harsh nor mild.

We also asked teachers about the amount of influence different groups have when it comes to determining discipline practices at their school.

• 67% say teachers themselves don’t have enough influence. Very few (2%) say teachers have too much influence, and 29% say their influence is about right.

• 31% of teachers say school administrators don’t have enough influence, 22% say they have too much, and 45% say their influence is about right.
• On balance, teachers are more likely to say parents, their state government and the local school board have too much influence rather than not enough influence in determining discipline practices at their school. Still, substantial shares say these groups have about the right amount of influence.

Teachers from low- and medium-poverty schools (46% each) are more likely than those in high-poverty schools (36%) to say parents have too much influence over discipline practices.

In turn, teachers from high-poverty schools (34%) are more likely than those from low- and medium-poverty schools (17% and 18%, respectively) to say that parents don’t have enough influence.

A Discrimination Report Card

We develop an empirical Bayes ranking procedure that assigns ordinal grades to noisy measurements, balancing the information content of the assigned grades against the expected frequency of ranking errors. Applying the method to a massive correspondence experiment, we grade the race and gender contact gaps of 97 U.S. employers, the identities of which we disclose for the first time. The grades are presented alongside measures of uncertainty about each firm’s contact gap in an accessible report card that is easily adaptable to other settings where ranks and levels are of simultaneous interest.
