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.
一株黏液型的红平红球菌对10%(体积/体积)的正十六烷具有抗性,而其粗糙型衍生物则敏感。当将黏液型菌株产生的胞外多糖(EPS)添加到粗糙型菌株的培养物中时,粗糙型菌株获得了对正十六烷的抗性。因此,EPS赋予了红球菌属成员对正十六烷的耐受性。
