Relationships between colony morphotypes and oil tolerance in Rhodococcus rhodochrous

Appl Environ Microbiol. 2000 Nov;66(11):5073-7. doi: 10.1128/AEM.66.11.5073-5077.2000.

Abstract

A mucoidal strain of Rhodococcus rhodochrous was resistant to 10% (vol/vol) n-hexadecane, while its rough derivatives were sensitive. When the extracellular polysaccharide (EPS) produced by the mucoidal strain was added to cultures of the rough strains, the rough strains gained resistance to n-hexadecane. Thus, EPS confer tolerance to n-hexadecane in members of the genus Rhodococcus.
