New #ISEPpapers! Updated classification of the phylum Parabasalia https://onlinelibrary.wiley.com/doi/full/10.1111/jeu.13035

"Most are harmless or beneficial gut #symbionts of #animals, but some have turned into #parasites in other body compartments, the most notorious example being #Trichomonas vaginalis in humans."

#Microbes used poison gas in battle for iron in the Earth's early oceans https://phys.org/news/2024-10-microbes-poison-gas-iron-earth.html

Inhibition of phototrophic iron oxidation by nitric oxide in ferruginous environments: Verena Nikeleit et al. https://www.nature.com/articles/s41561-024-01560-9

"A new study investigates how various #bacteria excrete insoluble iron as part of their metabolic processes. Some—the phototrophic iron oxidizers—gain energy by oxidizing Fe with the help of sunlight, and others by reacting Fe with nitrate as an oxidizing agent."

New #ISEPpapers #preprint! Insights from comparative plastid #genomics of colorless facultative pathogens #Prototheca (Chlorophyta): Unveiling membrane transport and organelle division as key functions https://www.biorxiv.org/content/10.1101/2024.01.16.575923v1.abstract #protists #algae #parasites #microbes @biorxivpreprint


New #ISEPpapers! Genomic analyses of Symbiomonas scintillans show no evidence for endosymbiotic #bacteria but does reveal the presence of #GiantViruses https://journals.plos.org/plosgenetics/article?id=10.1371%2Fjournal.pgen.1011218 #protists #symbiosis #viruses #genomics #microbes @PLOS by Anna Cho et al.


New #ISEPpapers #preprint! Comprehensive analysis of the microbial consortium in the culture of flagellate #Monocercomonoides exilis https://www.biorxiv.org/content/10.1101/2024.02.02.578639v2 #protists #microbes #mitochondria #bacteria #biorxiv @biorxivpreprint

"Monocercomonoides exilis is the only known amitochondriate eukaryote, making it an excellent model for studying the implications of mitochondrial reduction from a cellular and evolutionary point of view."


Follow the leader: A new study of #flagella in #algae reveals how they coordinate their movements to ensure cells steer efficiently https://elifesciences.org/digests/86102/follow-the-leader #protists #microbes

The younger flagellum sets the beat for #Chlamydomonas reinhardtii https://elifesciences.org/articles/86102

"To steer, C. reinhardtii adjusts the strength of the strokes made by each flagellum. Despite this asymmetry, the flagella must continue to beat in synchrony to move efficiently."


Mesmerising microbes: bacteria as you’ve never seen it before – in pictures

As a side hustle he manipulates and photographs the microbial world; his images are collected in a book, Beautiful Bacteria. Taking bacteria from substances such as wastewater, dental plaque or kimchi, Danino lets them multiply in a petri dish, adding dyes. The results are artworks differing from the digital enhancements often made in scientific photography to make images more informative.

#Mutualism on the edge: Understanding the #Paramecium–#Chlorella symbiosis https://journals.plos.org/plosbiology/article?id=10.1371%2Fjournal.pbio.3002563

"Exploring the mechanisms that underpin #symbiosis requires an understanding of how these complex interactions are maintained in diverse model systems. The ciliate #protist, Paramecium bursaria, offers a valuable insight into how emergent endosymbiotic interactions have evolved."

Minimalist or maximalist? The life of a #microbe a mile underground
https://phys.org/news/2023-11-minimalist-maximalist-life-microbe-mile.html paper: https://ami-journals.onlinelibrary.wiley.com/doi/10.1111/1462-2920.16543

Magdalena Osburn: "The deep subsurface #biosphere is enormous; it's just a vast amount of space... Many of the #microbes we found were either minimalist: ultra-streamlined with one job that it does very well alongside a close consortium of collaborators, or it can do a little bit of everything. These maximalists are ready for every resource that comes along."

Hoping to see some new #science folks exploring Mastodon so figured it’s time for another #introduction - I’m Mya, a professor at the University of South Florida College of Marine Science. Our lab studies #microbes (bacteria, viruses, protists) in the oceans and other environments and also works on #fish egg identification. I also post about my cute dog and cat a lot! #USFCMS #ocean #marine #oceanography #microbiology #virology #research #seagrass #urchin #academia


Endless microbes most beautiful and most wonderful

"To reflect the importance of microbes and to create a home for microbiology research using genetics, PLOS Genetics will be launching a new section on Microbial Genetics. "

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.

Rare opportunity to study short-lived volcanic island reveals sulfur-metabolizing #microbes https://phys.org/news/2023-01-rare-opportunity-short-lived-volcanic-island.html

The Early Microbial Colonizers of a Short-Lived Volcanic Island in the Kingdom of #Tonga https://journals.asm.org/doi/10.1128/mbio.03313-22

"We didn't see what we were expecting. We thought we'd see organisms you find when a glacier retreats, or #cyanobacteria, more typical early colonizer species—but instead we found a unique group of #bacteria that metabolize sulfur and atmospheric gases."
