Roseiflexus castenholzii
Description and Significance
Roseiflexus castenholzii is gram negative and is classified as a green, nonsulfur bacteria. Colonies that were found were red to reddish brown in color. Roseiflexus castenholzii is an unbranched multicellular filamentous organism that does not have a defined length but the diameter is .8 to 1.0 μm. R. castenholzii has no flagella and show signs of gliding motility. An unusual aspect of this organism is that it lacks chlorosomes, which can usually be found in related species, and intracytoplasmic membranes.
Roseiflexus castenholzii is thermophilic and found on microbial mats in hot springs, and was originally found in the Nakabusa hot springs in Japan. Ideal conditions to live at are a water temperature ranging from 45 to 55 degrees Celsius and a pH from 7 to 9. The organism can function under aerobic and anaerobic conditions.
Genome Structure
Roseiflexus castenholzii has a single, circular chromosome with a length of 5,723,298 base pairs. There are also 4,330 protein genes and 56 RNA genes. The G+C content of this organism is to some extent higher than other related species.
