''Chlorobium limicola'' is a
gram negative bacterial member of
green sulfur bacteria genus found in freshwater hot springs. ''C. limicola'' is a non-motile
mesophile
A mesophile is an organism that grows best in moderate temperature, neither too hot nor too cold, with an optimum growth range from . The optimum growth temperature for these organisms is 37°C. The term is mainly applied to microorganisms. Organi ...
, photoautotrophic/photosynthetic strict anaerobe important to carbon, nitrogen and sulfur cycles in anoxic freshwater environments.
Strain DSMZ 245 T was isolated from Gilroy Hot Spring and whole genome sequencing was accomplished.
Believed to be morphologically diverse, it was determined that culturing techniques determine some characteristics like slime production and morphology.
As a green sulfur bacteria, ''C. limicola'' fixes carbon via
reverse TCA cycle reactions.
Genetics
Whole genome sequencing was accomplished on Strain DSMZ 245 isolated from Gilroy Hot Springs.
Genome length: 2,763,181bp
Total genes: 2576
Protein coding genes: 2522
NCBI Accession
GCA_000020465
Biotech applications
''Chlorobium limicola'' has potential in biogas cleanup due to the hydrogen sulfide oxidization process capabilities. ''Chlorobium limicola'' reduces hydrogen sulfide to elemental sulfur which could eliminate the use of chloroform for the extraction of sulfur from water.
