Abstract
A Vitamin B12 preparation is obtained in a process which comprises providing an aqueous medium containing as essential ingredients inverted molasses and a yeast product, the molasses comprising 4 to 18 per cent by weight of the medium and the yeast product being present in an amount to provide an amino nitrogen content of substantially 0.048 to 0.24 per cent by weight of the medium, inoculating the medium with a culture of P. freudenreichii and fermenting for a period of days to develop Vitamin B12 activity. The yeast is preferably provided in the form of a yeast autosylate such as brewers yeast autosylate, the solids of which comprise from 1 per cent of the culture medium. The molasses employed may be beet molasses, blackstrap molasses or carrot molasses. The sugar content of the molasses should be inverted in which case an extraneous source of invertase may be added. Preferably the fermentation is carried out between 28-32 DEG C. and at a pH between 6.5 and 7.2 to which value it may be adjusted by the addition of ammonia. After fermentation for at least 3 to 4 days the culture is centrifuged and the cell cream dried. Examples describe the process utilizing liquid waste brewers yeast and beet molasses.
