[Heterogeneity of Rhodococcus opacus 1CP as a response to stress induced by chlorophenols].


PMID 16240653

Abstract

Dissociation of Rhodococcus opacus 1CP during culturing in different media (containing phenol and its monochlorinated derivatives as the sole source of carbon and energy) was studied. Three variants of strain 1CP (S1, S2, and R) differing in the morphology of cells and colonies, lipid composition, and manner of growth on phenol and monochlorophenols were isolated. It was shown that 2- and 4-chlorophenols were most actively degraded by the smooth (S) forms of the culture, and that the rough (R) form predominated when the culture was grown in a rich medium. The S forms differed from the R forms of the strain by an increased content of cardiolipin, fatty acids, and phosphatidylethanolamine.
