Single-cell or multicellular organisms for the production of riboflavin

摘要

The present invention relates to a single cell or multicellular organism, particularly a microorganism, for producing riboflavin biotechnologically. The characteristic of the above organism is that the synthesis amount of riboflavin, which does not supply glycine externally at all from this organism, is lower than that of wild-type Ashbia gocipyi species, i.e., ATCC10895, which is cultured under the standard conditions in which glycine of 6 g / /RTI is at least equal to that of glycine.
