In this study it was determined that under treatment of tomatoes root system with 3 times diluted supernatant of cultural liquid Rhodococcus erythropolis IMV с-5017, the number of fruits and their weight were 1.11.7 times higher than those for plants treated with water (control). In the case of treatment of barley seeds with 30 times diluted supernatants of culture liquid Nocardia vacсinii IMV В-7405, Acinetobacter calcoaceticus IMV B-7241 and Rhodococcus erythropolis IMV с-5017 yield increased by 58.55, 69.23 and 83.3%, respectively, compared with water seed treatment. The positive influence of extracellular exometabolites of surfactants producers on the yields of barley and tomatoes is the basis for the development of the technology of obtaining microbial preparations for application in crop production using cheap industrial wastes.
