Background
Riboflavin is also known as VB2, also known as vitamin G or lactoflavin, and belongs to water-soluble. It is indispensable to biological life activities, is an essential component constituting flavoenzymes, and directly participates in carbohydrate, protein and fat metabolism. If the food lacks riboflavin, a human body may develop a series of health problems due to the long-term lack of riboflavin. The method for producing riboflavin by fermentation has the advantages of mild reaction conditions, low cost, greenness, cleanness, environmental protection and the like. Therefore, the production of riboflavin by fermentation under the condition of low carbon and environmental protection has important significance.
The existing riboflavin production process has the disadvantages of complex fermentation material components, low conversion rate, long fermentation period and low yield, and simultaneously has serious sewage pollution after extraction, so that the production cost is high and the environmental cost is extremely high due to the influence of various aspects, which is mainly caused by the fermentation production process. Moreover, in the prior art, riboflavin is industrially produced by adopting a traditional culture medium for fermentation production, but the traditional culture medium generally contains cottonseed cake powder and beet molasses, the two components can provide nutrient substances required by growth and development for fermenting organisms, but long-term practice production and research show that the two components have some defects in the fermentation process, the solubility of the cottonseed cake powder is low, and the use of the cottonseed cake powder as a fermentation nitrogen source not only makes the fermentation liquor viscous but also reduces the concentration of dissolved oxygen in the fermentation liquor; the beet molasses contains more colloidal substances in the components, so that the fermentation liquor has early foaming time and larger foam in the fermentation process. These seriously affect the cycle time and yield of riboflavin production.
Disclosure of Invention
In order to solve the defects in the prior art, the invention aims at providing a clear liquid fermentation culture medium for producing riboflavin and aims at providing a method for producing riboflavin by fermentation by using the clear liquid fermentation culture medium.

The invention provides a new process for clear fermentation culture of riboflavin, which has the advantages of mild reaction conditions, low cost, greenness, cleanness, environmental protection and the like.
2. The clear liquid fermentation culture medium is optimized by the traditional fermentation culture medium, unnecessary components such as cottonseed cake powder, beet molasses and the like are removed, and the clear liquid culture medium containing components such as corn steep liquor dry powder, yeast extract, magnesium sulfate, betaine, dipotassium hydrogen phosphate, diammonium hydrogen phosphate and the like is adopted. The invention uses yeast extract to replace cottonseed cake powder, the yeast extract is a full-solubility nitrogen source, and the amino acids and the nucleotide substances in the components are more abundant than the cottonseed cake powder; the betaine is one of the main components of the beet molasses, and the invention uses the betaine to replace the beet molasses, not only retains the main components, but also removes colloidal substances which have adverse effect on riboflavin fermentation, and further improves the quality of fermentation liquor.
