Acidobacteriota
Acidobacteriota is a diverse lineage of Gram‑negative bacteria that was first discovered in acidic soils. It is placed within the domain Bacteria and comprises several phyla that are sometimes referred to as Acidobacteria. The group was formally recognized in the early 2000s when molecular phylogenetics revealed its distinctness from other bacterial lineages. Members are found globally, especially in terrestrial and aquatic habitats, and they constitute a significant fraction of microbial communities in environments ranging from forest soils to a variety of sediments.
Morphologically, Acidobacteriota cells are typically rod‑shaped, pleomorphic, or filamentous. They lack distinctive spores and generally exhibit
Ecologically, Acidobacteriota play an essential role in carbon cycling. They contribute to the decomposition of plant
Genomic analyses have revealed that Acidobacteriota genomes are highly variable in size, ranging from about 2.5
Acidobacteriota thus represent a taxonomically and ecologically significant bacterial group whose study enhances our understanding of
