Abstract
The invention discloses monascus ruber strain with high extracellular yellow pigment yields, a method for breeding the monascus ruber strain and application thereof. The monascus ruber strain is named as monascus ruber WQ15 and is preserved in the China General Microbiological Culture Collection Center of the China Committee for Culture Collection of Microorganisms of the institute of microbiology of the Chinese Academy of Science in the No.3 yard on the No.2 Beichen West road of the Chaoyang district of Beijing on 2 July, 2015, and a preservation number of the monascus ruber strain is CGMCC No.10910. The monascus ruber strain with the high extracellular yellow pigment yields is obtained from riginal strains by means of ultraviolet mutation breeding. The monascus ruber strain with the high extracellular yellow pigment yields, the method and the application have the advantages that color level of extracellular yellow pigment of the monascus ruber strain is upgraded by 72% as compared with original strains by means of conventional liquid fermentation; the color level of the extracellular yellow pigment of the monascus ruber strain can be upgraded by 7.04 times as compared with the original strains if the monascus ruber strain is refilled with 300g/L of glucose during fermentation, and accordingly the monascus ruber strain can be used for producing the extracellular yellow pigment.
