摘要： A process for producing riboflavin, comprising culturing riboflavin producing fungi in a culture medium in which a vegetable oil or an animal oil is used as a carbon source so as to effect formation and accumulation of riboflavin and harvesting the riboflavin, characterized in that a carrier constituted of a clay mineral capable of adsorbing oil contents or a product of chemical treatment thereof or a calcium compound is incorporated in the culture medium. This process enables carrying out the concentration and recovery of riboflavin at low cost without the need of time-consuming operation, so that riboflavin can be produced in a high production rate with a high yield, and further enables effectively utilizing waste vegetable oils or animal oils to be disposed of for the recovery of riboflavin.

摘要： A method of producing riboflavin by culturing riboflavin-producing microbes in a culture ground using a plant oil or an animal oil as a carbon source, forming and accumulating riboflavin therein and collecting riboflavin therefrom, wherein a carrier of a clay mineral having oil-adsorbing property, a chemically treated product thereof or a calcium compound is made present in the culture ground. The riboflavin is produced maintaining a high yield and at an increased production rate at a low cost without requiring cumbersome operations for concentrating and recovering the riboflavin. It is further allowed to recover the riboflavin by effectively utilizing the waste plant oil or the waste animal oil that is to be disposed of.
