Examination of Processes of Cultivation of V. cholerae strains - Producers of Protective Antigens of Cholera Bivalent Chemical Vaccine in Tablets - in the Engineered Bioreactor

Studied is the kinetics of major antigen accumulation at growing of Vibrio cholerae M-41 Ogawa and 569 B Inaba strains in industrial and engineered reactors. Demonstrated is the possibility to obtain conditional native protective antigens in the engineered bioreactor. Shown is the identity of physiological and morphological properties of industrial Vibrio cholerae strains during their submerged cultivation in industrial and engineered bioreactors. Cholera bivalent chemical vaccine obtained using engineered bioreactor possesses quality indices meeting the requirements of normative documents and equal to those of preparation received by traditional approach.
