MICROORGANISM PRODUCING RIBOFLAVIN AND METHOD FOR PRODUCING RIBOFLAVIN USING THE SAME MICROORGANISM

摘要

PURPOSE: A microorganism, Bacillus subtilis, producing riboflavin and having resistance to proline analogue and a method for producing riboflavin using the same are provided, thereby mass-producing the riboflavin. CONSTITUTION: A microorganism, Bacillus subtilis CJKB0001 (KCCM-10445), having resistance to proline analogue produces riboflavin, wherein the Bacillus subtilis CJKB0001 (KCCM-10445) is obtained by inducing mutation of a parent microorganism, Bacillus subtilis AS5, using N-methyl-N'-nitro-N-nitrosoguanidine, and selecting a strain showing the excellent riboflavin producing activity therefrom. A method for producing riboflavin comprises culturing Bacillus subtilis CJKB0001 (KCCM-10445) in an appropriate medium.
