K. Zabolotny of the National Academy of Sciences of Ukraine popup.description1 Development of microbial biotechnology for accelerated restoration of freshwater reservoirs from anthropogenic pollution caused by toxic chemical and biogenic substances based on the complex use of effective microorganisms - destructors of toxic substances, and probiotic compositions and metabolites of microorganisms, to increase the resistance of hydrobionts to the toxic effects of pollutants and prevent the development of infectious aquaculture diseases. popup.description2 As a result of the work by stage, an analysis of the literature on the use of lactic acid microorganisms in aquaculture was conducted. 32 strains of gram-positive microorganisms that did not form spores, did not have catalase and cytochrome oxidase activities, and did not reduce nitrates from nitrites were selected for further work. All studied strains grew at a temperature of +30-20C, 2-4% NaCl in the medium and at a pH of the medium pH 4.0 - 6.0. According to physiological-biochemical and morphological-cultural features, these strains were preliminarily attributed to bacteria of the genus Lactobacillus (26 strains) and bacteria of the genus Enterococcus sp (7 strains). The isolated strains of MKB are not resistant to a wide range of antibiotics with different mechanisms of action, demonstrate high antagonistic activity against a wide range of pathogens that cause infectious diseases of fish, are promising probiotic strains for aquaculture production Product Description popup.authors Ananko Yevhen F.
