Zabolotny of the National Academy of Sciences of Ukraine popup.description1 Conducting research on determining the optimal parameters of cultivation, standardization and storage of bacterial concentrates of spore microorganisms popup.description2  Report: 13 pages, literature sources. 8. Object of the study: Microorganisms of the genera, Bacillus sp. growth characteristics under fermentation conditions, nitrogen-fixing microorganisms, Lip Test "Extender for inoculation", soil samples, ecological and trophic groups of microorganisms. It was established that: Optimal growth parameters can be reproduced under conditions of industrial fermentation. That is, it is possible to carry out an effective fermentation process of the listed microorganisms and obtain a culture liquid with a high titer of colony-forming units. It was found and practically proven that the optimal cultivation parameters for Bacillus sp. are cultivation with constant stirring in a turbulent flow, in a series of studies it was confirmed that the optimal range of cultivation temperature is 29-32°C at a pH range of 7.0 - 7.4 and aeration of 0.4 vol. Surface/1 vol. culture. species. Cultivation should be carried out for at least 36 hours. Testing the effect of the Testa Lip inoculation extender on the storage of high concentrations of microorganisms showed the feasibility of its use. Quantitative characteristics of ecological and trophic groups of soil microorganisms were determined and the main coefficients indicating the biological activity of soils were determined.
