Abstract

Invenţia se referă la biotehnologia microbiologică şi poate fi aplicată la obţinerea compuşilor biologic activi.Procedeul propus include cultivarea Propionibacterium freudenreichii s.s. shermanii în mediu nutritiv ce conţine extract de porumb, glucoză, CoCl2•6H2O, (NH4)2SO4 şi 5,6-dimetilbenzimidazol la agitarea culturii microorganismelor, unde cultivarea microorganismelor se efectuează în condiţii facultativ aerobe cu pH 6,8-7,0 în mediu nutritiv ce conţine, în g/l:unde introducerea în mediu nutritiv a 5,6-dimetilbenzimidazolului şi agitarea culturii se efectuează pe parcursul fazei a doua a fermentării.Rezultatul tehnic al invenţiei constă în optimizarea condiţiilor şi obţinerea componenţei mediului de cultivare care asigură o sinteză sporită a cianocobalaminei şi porfirinelor.
