Rhodococcus baikonurensis BTM4c, a boron-tolerant actinobacterial strain isolated from soil

Biosci Biotechnol Biochem. 2010;74(1):178-81. doi: 10.1271/bbb.90464. Epub 2010 Jan 7.


By screening a bacterial population from the soil in Tokyo, Japan, we isolated a boron-tolerant bacterium, strain BTM4c. Strain BTM4c grew under the boron excess conditions with 100 mM boric acid, which is generally toxic to bacteria. Molecular phylogenetic, chemotaxonomic, and physiological data showed that the strain belongs to the genus Rhodococcus, and is to be identified as Rhodococcus baikonurensis.
