#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."

Reasons to Hope: Palm Oil Alternatives Made Without Deforestation
Environmental organisation Milieudefensie have calculated that every second, around 169 trees are cut down in tropical rainforests. So the race is on to find a real solution to stop this!…Palm Oil Detectives
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."
Minimalist or maximalist? The life of a microbe a mile underground
If you added up all the microbes living deep below Earth's surface, the amount of biomass would outweigh all life within our oceans.Amanda Morris (Phys.org)

Long-read-based genome assembly reveals numerous endogenous viral elements in the green algal bacterivore Cymbomonas tetramitiformis
Abstract. The marine tetraflagellate Cymbomonas tetramitiformis has drawn attention as an early diverging green alga that uses a phago-mixotrophic mode of nutriGyaltshen, Yangtsho (Oxford University Press)
Encyclopaedia of DNA polymerases localized in organelles: Evolutionary contribution of diverse bacteria including the proto-mitochondrion
DNA polymerases (DNAPs) synthesize DNA from deoxyribonucleotides in a semi-conservative manner and serve as the core of DNA replication and repair machineries.bioRxiv
"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. "

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.

Molecular hydrogen in seawater supports growth of diverse marine bacteria - Nature Microbiology
Genome-resolved metagenomics, biogeochemistry, modelling and culture-based analysis reveal that marine bacteria consume H2 to support growth.Nature
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."
Rare opportunity to study short-lived volcanic island reveals sulfur-metabolizing microbes
In 2015, a submarine volcano in the South Pacific erupted, forming the Hunga Tonga Hunga Ha'apai island, destined to a short, seven-year life.Science X (Phys.org)
