Method for promoting spore production of monascus through co-culture of saccharomycetes and monascus

Abstract

The invention relates to the technical field of microbial reproduction, and provides a method for promoting spore production of monascus by co-culture of saccharomycetes and monascus, i.e., mixing two types of Feibaiberg's yeasts according to an inoculation ratio of 1: 1, and co-culturing the obtained mixture and monascus on a flat plate. The method disclosed by the invention has the advantages that it is found for the first time that the Feibeijerzewalski yeast strain can generate heat-resistant substances for promoting spore production of the monascus, and a new method for promoting spore production of the monascus is established; by adopting the method disclosed by the invention, the sporulation quantity of monascus can be simply, conveniently, effectively and greatly increased.

Description

technical field [0001] The invention relates to the technical field of microorganism propagation, in particular to a method for co-cultivating yeast and monascus to promote sporulation of monascus. Background technique [0002] Monascus purpureus (Monascus purpureus Went.), Chinese alias red yeast rice, red rice, red rice, a genus of fungi Ascomycetes Aspergillus family fungi in the order Phytomycetes, exist in trees, soil and accumulations, etc., representative species such as Monascus purpureus, Monascus Anka, Monascus red, Monascus Buck, Monascus smoke, Monascus berry rust, Monascus red. [0003] Monascus spores can be used in the production of red koji products, but there are few studies on spore production by solid-state fermentation of Monascus, and most of the methods reported to promote spore production by molds including Monascus are to optimize the spore production medium (carbon source , nitrogen source and inorganic salts, etc.) and culture conditions (medium te...

AI Technical Summary

Problems solved by technology

[0003] Monascus spores can be used in the production of red koji products, but there are few studies on spore production by solid-state fermentation of Monascus, and most of the methods reported to promote spore production by molds including Monascus are to optimize the spore production medium (carbon source , nitrogen source and inorganic salts, etc.) and culture conditions (medium temperature, medium pH value, inoculum size, etc.), some researchers have also reported the effect of light induction on sporulation

However, because the spore production ability of Monascus is generally weak, it is actually difficult to significantly increase the spore production of Monascus only through the optimization of the above solid-state spore production conditions.
