Biology:Abyssobacteria

From HandWiki

Abyssobacteria is a phylum of bacteria in the Patescibacteria group, characterized by small genomes and deep-branching phylogeny.[1][2]

Etymology

The name ''Abyssobacteria'' derives from Latin ''abyssus'' (deep) and ''bacteria'', referring to their prevalence in deep subsurface habitats.[3]

Characteristics

Abyssobacteria are characterized by ultra-small cell sizes (typically <0.2 μm), reduced metabolic pathways, and dependence on host bacteria for nutrients, often in anoxic aquifers and deep subsurface sediments.[4] They exhibit limited fermentation capabilities and lack many biosynthetic genes, reflecting their parasitic or symbiotic lifestyles.
