[Peculiarities of surface-active trehalose mycolates synthesis of Rhodococcus erythropolis EK-1].

It has been established that activity of trehalosephosphate synthase (key enzyme of trehalosemycolates synthesis) under cultivation of Rhodococcus erythropolis EK-1 on the medium with n-hexadecane was 10 times higher, and amount of synthesized surface-active substances 4 times higher as compared to the growing of EK-1 strain on ethanol. Introduction of 0.2% of fumarate and 0.

[Particularities of alkane oxidation in Rhodococcus erythropolis EK-1 strain--producer of surface-active substances].

The hexadecane oxidation of Rhodococcus erythropolls EK-1 was established to be catalyzed by the alkane hydroxylase complex containing Fe-S proteid rubredoxin. Alkane hydroxylase activity was increased twice in the presence of 10 mg/l iron ions in the cultivation medium. Sodium ions were shown to be an activator of alkane hydroxylase.
