Acidobacterium capsulatum is an acidophilic chemotrophic organism first cultured in 1991. Its genome was reported in 2009. Organisms in this phylum are ubiquitous in the environment. Genomic information suggests that A. capsulatum may be a key decomposer in soil and aquatic environments because of the number of potentially encoded polysaccharide-degrading enzymes capable of providing simple sugars. However, A. capsulatum may not be able to metabolize...
