| Popis: |
The actual problem in the development of new and improvement of existing forms of microbial preparations for crop production is the search for technological and economical components of the substrate to increase the titer of bacteria and keep their viability for a long period. The aim of our research was to study the technological effectiveness of the oilcake obtained after oil extraction from seeds of Linum usitatissimum L. (flax) and Brassica spp. L. (mustard) as a component of a liquid nutrient medium for the cultivation of associative bacteria. The addition of mustard and flax cake to the cultivation medium of P. polymyxa CCM P contributed to an increase in the titer of bacteria by 3.1 and 4.3 times, respectively, compared to control. We found that mustard cake has a stimulating and stabilizing effect on P. polymyxa CCM P, as well as a stabilizing one on L. nimipressuralis 32-3 CCM when storing for a month. |
