Abstract
The invention relates to the microbiological biotechnology, in particular, to the media for Propionibacterium freudenreichii s.s. chermanii cultivation the cyanocobalamin and porphyrin producer.The summary of the invention consists in the fact that it is propesed a medium for Propionibacterium freudenreichii s.s. chermanii cultivation, comprising: corn extract, glucose, (NH4)2 SO4, CoCl2 · 6H2O, 5,6 dimethylbenzimidase, wherein as stabilizing and stimulating factor supplementary is added lipidic extract of Porphyridium cruentum red alga in the following component quantitative ratio, g/l:5,6 dimethylbenzimidase 0,02-0,03The technical result of the invention consists in the fact that the proposed medium ensures a high level of the culture productivity - 10,9 g/l of absolutely dry biomass in comparison with the prototype - 7,8 g/l; the culture grwn on the said medium synthesizes 2,4 time more than cyanocobalamin and 1,6 times more with the prototype; the proposed medium ensures the productivity stability of the culture grown on it.
