Abstract

A material which on oxidation yields riboflavin and which is described as a riboflavin precursor is prepared by inoculating a nutrient riboflavin-containing mash having a riboflavin concentration of at least 65 m g per c.c. with an active culture of bacteria which synthesizes substantially no additional riboflavin in said mash and which is active to produce an Eh value of - 0.096 volt or less and to yield a precipitate of said riboflavin precursor. The preferred temperature of the insulation is in the range 8-47 DEG C. Bacteria which are mentioned as suitable for the process of the invention are streptococci f calis, liquefaciens, cremoris, zymogenes and lactis, Escherichia coli, Clostridium acetobutylicum, Clostridium saccharo-butyl-acetonicum-liquefaciens-delta, and serratia phymouthensis. The preferred nutrient mash is that obtained by fermenting a sterile mash containing as the substrate proteins and carbohydrates with an acetine culture of the fungus Eremothecium Ashbyii in the presence of abundant aeration. Specification 621,468 is referred to.
