| abstract | 1,169,933. Vitamin B 12 . RICHTER GEDEON VEGYESZETI GYAR RT. 29 Nov., 1966 [8 Dec., 1965], No. 53479/66. Heading C2V. In a process for the adaptation of a Vitamin B 12 -producing bacterium population derived from sewage sludge, the bacterium population is subjected to at least five serial fermentation steps, whereby the bacterium population is adapted to proliferate and to produce Vitamin B 12 in the absence of sewage sludge, each fermentation step being carried out in an aqueous nutrient medium containing methanol, at least a part of the broth from one fermentation step being used as inoculum for the subsequent fermentation step. The adapted bacterium population so-produced is cultured in aqueous nutrient medium containing methanol to produce Vitamin B 12 with adding further sewage sludge. In one example a portion of the broth from each fermentation step is added to further nutrient medium and in another example a portion of the broth from each fermentation step is removed and replaced by fresh nutrient medium. The aqueous nutrient medium contains methanol, molasses, yeast hydrolysate, liver extract, cornsteep liquor, ammonium hydrogen carbonate, ammonium hydroxide, magnesium chloride, 5,6-dimethylbenzimidazole, cobalt nitrate, glycine, succinic acid, sodium hydrogen sulphite, o-xylidine and superphosphate. |
