K. Zabolotny of the National Academy of Sciences of Ukraine popup.description1 Оptimizing the conditions for obtaining liquid bacterial concentrates and developing methods for their standardization with the aim of further use as part of biological preparations for complex plant protection popup.description2  Object of research: Microorganisms of the genera Pseudomonas sp., Bacillus sp. growth characteristics under fermentation conditions. 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 Pseudomonas sp. and for Bacillus sp. are cultivation with constant stirring in a turbulent flow, in a series of studies it was confirmed that the cultivation temperature is 28°C at a range of pH- 6.6 - 7.4 and aeration of 0.2 vol. Air/1 vol. culture. genus. Cultivation must be carried out for at least 48 h Product Description popup.authors Ananko Yevhen F. Vasyliuk Olha M. Nikolaienko Ihor V. Skrotskyi Serhii O.
