Bacterial aerobic methane cycling by the marine sponge-associated microbiome - Microbiome
Background Methanotrophy by the sponge-hosted microbiome has been mainly reported in the ecological context of deep-sea hydrocarbon seep niches where methane is either produced geothermically or via anaerobic methanogenic archaea inhabiting the sulfa…BioMed Central

High-resolution metagenomic reconstruction of the freshwater spring bloom - Microbiome
Background The phytoplankton spring bloom in freshwater habitats is a complex, recurring, and dynamic ecological spectacle that unfolds at multiple biological scales.BioMed Central
Blooms of #Cyanobacteria pose a significant threat to #freshwater systems including rivers driving both #eutrophication and its dire implications for freshwater species as oxygen availability plummets and also the additional threat posed by #cyanotoxins produced by some Cyanobacteria.
This new research in Scientific Reports takes a #metagenomics and Q-PCR approach to explore the composition of the Cyanobacterial populations and their cyanotoxin production gene in major rivers across the United States (in 2019) and identifies Microcystis as the key toxin producing genus across this study.

"Here, we identified an endogenous cGAS-like enzyme in Pseudomonas aeruginosa that generates 3′,3′-cGAMP during phage infection, signals to a phospholipase effector, and limits phage replication."

Bacteriophages inhibit and evade cGAS-like immune function in bacteria
Bacteriophages antagonize cGAS-like bacterial immunity by sequestering immune signaling molecules and acquiring capsid gene mutations.Cell
We are all too familiar with the all-too-often catastrophic impacts of #COVID19 #infection on human #health.
This fascinating new #metagenomics research in mBio explores a potentially important and intriguing link between the presence and relative abundance of different functional guilds present in the human gut #microbiome (including short chain fatty acid biosynthesis and virulence functions) and disease severity and outcomes resulting from the virus. Clearly a subject for future extended studies to explore potential increases in severity due to infection and exacerbated or mitigated by differences in gut microbiomes.

As we (humans) get to grips with how to scale up #hydrogen as an energy source (and for energy storage) and as part replacement for #fossilfuels, this new research (once again) shows that #microbes have beaten us to it and evolved their own solutions for energy - in this case using hydrogen power.
This new research in Nature Microbiology explores how hydrogen in seawater supports growth of multiple and diverse #bacterial species.
Fof those (like me) in #Melbourne , you may be interested that the research also includes study of this process within #PortPhillipBay sediments.

#Virus control
This exciting new research explores the influence of #virus #infection in changing the balance of organic matter degradation between #bacteria and #eukaryotes in #marine #carboncycling during #phytoplankton blooms.
Based on #mesocosm studies, this research demonstrates how #viruses infecting different #microorganisms change community dynamics and the release and potential fate of marine carbon from primary production.

Bacterial lifestyle switch in response to algal metabolites
Opportunistic bacteria modulate their lifestyle from coexistence to pathogenicity by perceiving the physiological state of their algal host through sensing of algal secreted metabolites.Noa Barak-Gavish (eLife Sciences Publications, Ltd)

Monir Moniruzzaman Studies the Secrets of Giant Viruses
The University of Miami researcher studies how a mysterious group of supersized viruses infects and influences the evolution of their hosts.James M. Gaines (The Scientist Magazine)
When I started my lab a few years ago I started building up an in-house library for students. Two of the first books I bought are The Logic of Chance (Eugene Koonin) and The Origins of Genome Architecture (Michael Lynch). Both are remarkable books that discuss genomics in the context of microbial diversity and the tree of life.
What other genomics/evolution classics do people always keep around?
