Rezumat

Present work reports bioreactor AF-0.170 test results. This novel bioreactor was designed in ETI “Biotechnica” of NAAS for small-scale microbial pesticides production on the base of biolaboratories and biofactories. Cell concentration in culture liquids of microbial preparations based on Beauveria Bassiana and Pseudomonas fluorescens obtained in tests had an order of 109 CFU∙ml–1and contamination level was not exceed 0.3%. Results analyses demonstrated 2.4 times increasing of preparation yield per cycle combined with moderate decreasing of cell density in culture liquid for submerged fermentation in bioreactor versus shaker technology. Advantages of self contained bioreactor usage for small-scale scale microbial pesticides production at Ukrainian and Moldovan biofactories are shown.
