Chloracidobacterium is a genus of the Acidobacteriota.[4] It is currently assigned to the family Acidobacteriaceae, but phylogenetic evidence suggests that it belongs in Blastocatellia.[5]
This is a group of photosynthetic bacteria were discovered in 2007 and their identification extends the number of bacterial phyla that can carry out chlorophyll-based photosynthesis from five to six.[3][6]
"Candidatus Chloracidobacterium thermophilum"
The organism "Candidatus Chloracidobacterium thermophilum" was initially detected through the bioinformatics analyses of metagenomic sequence data from the microbial mats collected from a hot spring in Yellowstone National Park.[7] It was later isolated after the inhibition of Synechococcus species in the microbial mats samples, leading to a co-culture C. thermophilum, Anoxybacillus species, and Meiothermus species. C. thermophilum was plated on Midnight Medium (CTM) media to culture it for pure isolation. Genomic sequencing of the bacterium revealed that it did not contain genes for the enzymes to reduce sulfate, yet it was dependent on a reduced sulfur source. The researchers likely speculated that it shared a mutualistic relationship with the cocultures of Meiothermus species and Anoxybacillus species for access to reduced sulfur sources. In addition, the bacterium was determined to be aerophilic, moderately thermophilic, anoxygenic and photoheterotrophic. Ultimately, they found that it is dependent on a reduced sulfur source, bicarbonate, L-lysine, and vitamin B12 for pre culture isolation.[7]
