Abstract

The invention provides a monascus purpureus bacterial strain with the collection number of CGMCC 11611. The invention further provides a method for fermenting and producing monascus pigment by the bacterial strain. The method includes the steps: (1) taking collected monascus purpureus and performing spore cultivation to obtain spore suspension; (2) inoculating the spore suspension into a fermentation medium, fermenting and cultivating the spore suspension for 36-60 hours, adding L-type amino acid and D-type amino acid into the fermentation medium, and continuing fermentation and cultivation; (3) extracting the monascus pigment by ethyl alcohol after fermentation. The invention discloses a novel monascus purpureus bacterial strain which can be used for fermenting and producing the monascus pigment. According to the fermenting and producing method of the monascus pigment, the amino acid serves as an inductive agent and induces the monascus purpureus to generate the monascus pigment, lipase activity is reduced to be lower than 110U by the prepared monascus pigment, the amino acid is low in cost, easily obtained and high in induced generated pigment content and has high lipase inhibitory capacity, and the method for fermenting and producing the monascus pigment is simple and easy to operate.

Description

Technical field [0001] The invention belongs to the technical field of microbial fermentation, and specifically relates to a Monascus purpureus strain and a method for fermenting and producing monascus pigment by using the strain. Background technique [0002] Obesity has become a common disease in my country and many European and American countries. There are many factors that cause obesity, including genetic factors, environmental factors, eating habits, living habits, etc. Among them, excessive eating, especially excessive intake of high-fat foods, is the main cause of obesity. Therefore, obese people should not only reduce the calories of food, but also limit the intake of fat. One way to limit fat intake is to inhibit the activity of lipase in the body. If it can prevent the digestion and absorption of fat, it should be accompanied by a low-fat diet. The obesity and disease caused will be greatly improved. Lipase can hydrolyze fat into free fatty acids and glycerol, and li...
