Abstract

The invention can be used to get farlutating thallus powder by deep submerged fermentation in liquid. Whicn can be used to make all kinds of food or drug for depress blood fat. The whole manufactory process of monascus thalli powder follows five steps. 1, pure bred on bevel. 2, rocking seed in two level. 3, culture in seed tank. 4, fermentation and culture in fermenter tank..5, get monascus thalli powder containing 1.2% farlutating after abrading, isotroping and atomized drying the monascus thalli. The craft is easy and parameter can be controlled. The whole production is airproof so it is different to be polluted. The outcome is pure and its quality is good. Besides, the labour intensity is low.

Description

The liquid submerged fermentation method is produced the method that contains lovastatin thalline powder
Technical field:
The present invention relates to a kind of preparation method of bacterial classification powder, relate in particular to a kind of liquid submerged fermentation method and produce the method that contains 1.2% lovastatin thalline powder.
Background technology:
Monascus is to be used for producing the main bacteria seed of wine of rice fermented with red yeast and monascorubin to wait the food color of works to its fermented product red colouring agent for food, also used as a Chinese medicine, the existing loading of the application of food antiseptic and drug medical aspect at the history of the existing more than one thousand years of China " Compendium of Materia Medica) ", " animal doctor this chapter) ", " Tian Gong Kai Wu) ".After Japan rattan chapter professor far away isolated cholesterol synthesis inhibitor from red monascus in 1979, the function of monascus and application are subjected to domestic and international extensive concern, obtained comprehensive deep research, the existing how tame food company of Japan drop into product that a large amount of manpower and materials carry out the listing of health red rice development of food can reducing blood-fat be popular and for inventor China of red colouring agent for food, also used as a Chinese medicine not show song protective foods take advantage.The functional Monascus product has only several places such as Fujian, Zhejiang, Hebei that production is arranged in China, the red colouring agent for food, also used as a Chinese medicine made by the monascus fermentation such as the zhibituo in Pekinese's Xuezhikang, Chengdu also occupies certain market as blood lipid-lowering medicine in addition.But generally speaking, the shared market share of functional Monascus product is also little, the lovastatin that monascus ruber produces is very big and be free from side effects to reducing blood lipid, and the functional Monascus that China produces now is still with the ancient method of koji tray or aerated koji making, labour intensity is big, easy pollution of products, it is low that product contains lovastatin.
Summary of the invention:
Effects such as technical problem to be solved by this invention provides a kind of liquid submerged fermentation method for preparing and produces the method that contains 1.2% lovastatin thalline powder, and it is simple that this method has production technique, and the health-care effect of product purity and product is obvious.
The present invention selects tens strain monascus rubers through separating, screening, and obtains the higher red monascus of strain product lovastatin and passes through ultraviolet ray and cobalt 60 (Co again 60) shine repeatedly and carry out mutagenesis.Obtain the mutagenic strain T-180 that a plant height produces the red monascus of lovastatin.
The applicant is deposited in China Committee for Culture Collection of Microorganisms common micro-organisms center on May 19th, 2004, and it abbreviates CGMCC as, and deposit number is 1148.The address of China Committee for Culture Collection of Microorganisms's common micro-organisms center (it abbreviates CGMCC as) is: No. 13, North No.1 Row, Zhongguancun, Haidian District, Beijing City, Institute of Microorganism, Academia Sinica (100080).
The mutagenic strain T-180 classification called after of the red monascus of this high yield lovastatin: belong to the red monascus bacterial classification.
The content that the monascus thalline powder that the present invention utilizes this this bacterium to make contains lovastatin is 1.2%, the content that is higher than the functional red yeast rice lovastatin of present China far away, and I am the production of adopting the automatic controlled liq submerged fermentation of a complete set of sealing, the purity height, produce and stablize, be difficult for the modern production technology of polluting.
The present invention adopts a plant height of my mutagenesis to produce the red monascus mutagenic strain T-180 of lovastatin through slant culture one-level shake-flask culture, the secondary shake-flask culture, again through seed tank culture, arrive fermentor cultivation again through defibrination, the homogeneous spraying drying powder-forming, promptly contain 1.2% lovastatin monascus thalline powder and be pink, with medicine and the food of making various reducing blood-fat.
