| 摘要 |
A process for producing riboflavin glucoside comprises cultivating a microorganism belonging to the genus Bacillus, such as Bacillus brevis, Bacillus cereus, Bacillus circulans, Bacillus coagulans, Bacillus licheniformis, Bacillus megaterium, Bacillus pumilus or Bacillus subtilis, which is capable of producing riboflavin glucosides, in an aqueous medium containing a starch under aerobic conditions. Amongst the preferred strains are Bacillus subtilis RB50::[pRF69]60Ade+ and Bacillus subtilis RB50::[pRF69]60[pRF93]120Ade+. The so-produced riboflavin glucoside can be used as a more soluble substitute for riboflavin to prepare clear drinks and injection solutions.
