Abstract

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.
