title: [Synthesis of surfactants acinetobacter calcoaceticus IMV B-7241 and Rhodococcus erythropolis IMV Ac-5070 in the medium with glycerol].
abstract: It was established that glycerol, a byproduct of biodiesel production, may be used as substrate for synthesis of surfactants Rhodococcus erythropolis IMV Ac-5017 and Acinetobacter calcoaceticus IMV B-7241. Maximum indices of surfactants synthesis by the strain IMV B-7241 have been fixed, when the medium with glycerol included yeast autolysate and trace elements. It was shown that the surfactants synthesis could be intensified when cultivating A. calcoaceticus IMV B-7241 and R. erythropolis IMV Ac-5017 on the mixture of hexadecane and glycerol in concentration of 0.5-1.0% (in volume). When using inoculate grown on hexadecane, the conditional concentration of the surfactant A.calcoaceticus IMV B-7241 on the mixed substrate was higher by 56-100, and that of R. erythropolis IMVAc-5017 by 260-320 % than on the monosubstrate glycerol. The paper is presented in Russian.
