The possibility of simultaneous synthesis of surfactants with antimicrobial properties and phytohormones (auxins, cytokinins and abscisic acid) by Acinetobacter calcoaceticus ІMV B-7241 was revealed. It was shown that the survival of cells (105–107 cells/ml) of the Pseudomonas and Xanthomonas phytopathogenic bacteria was within 0–33 % range after the treatment with surfactant solution (0.15 mg/ml) for 2 h. The dependence of qualitative and quantitative composition of auxins and cytokinins on the nature of carbon source in the medium cultivation (ethanol, glycerol, refined and frying sunflower oil) was shown. The maximum concentration of auxin (122.04 μ/l) and cytokinins (363.93 μ/l) was observed at cultivation of A. calcoaceticus ІMV B-7241 in medium with glycerol. The data obtained serve as the grounds for the development of technology of complex microbial preparations production with different biological properties for agricultural use.
