Abstract
The invention belongs to the technical field of industrial cultivation for edible funguses, and particularly relates to a sparassis crispa liquid strain culture medium and a culture method. The formula of the culture medium comprises 0-145 g/L of glucose, 0-70 g/L of glutinous rice flour, 1-6 g/L of fish meal peptone, 0-5 g/L of KH2PO4 and 0-3 g/L of MgSO4.7H2O, the original pH is 5-6, and the culture medium is cultured by preparation of sparassis crispa liquid mother strains and preparation of sparassis crispa liquid original strains. Aiming at the defects that the sparassis crispa liquid culture medium is high in cost and limited in raw material sources, the invention provides the sparassis crispa liquid strain culture medium and the culture method. The production cost is reduced, and the production efficiency is improved. The liquid culture medium has the advantages of being simple in formula and convenient in raw material sources and is suitable for large-scale production. The liquid strain culture process is simple, and the operation is convenient.
Description
Technical field
The invention belongs to edible fungus industrial cultivation technical field, be specifically related to a kind of Sparassis crispa liquid spawn culture medium and cultural method.
Background technology
Sparassis crispa (
sparasis latifolia) have another name called silk ball gill fungus, silk ball mushroom, because of its sub real limb complications, be similar to huge silk ball and gain the name, being described as the magical mushroom of illusion in Japan, is a kind of food (medicine) edible mushroom new varieties recently developed, and its famous and precious degree can the treasure such as Cordyceps sinensis, hickory chick, ferfas shoulder to shoulder.According to surveying and determination, crude protein content 12.9 % in Sparassis crispa fruit body dry product, raw fiber 13.7 %, amino acid classes is comparatively complete, and containing a large amount of mineral matters, as iron (48.1 mg/kg), zinc (38.5 mg/kg), manganese (30.6 mg/kg) equal size are all higher, vitamin content is also very abundant, as vitamin C, vitamin D, vitamin E etc., wherein content of vitamin E occupies Homonemeae food prostatitis in " composition table of foods ".Sparassis crispa not only delicious flavour, be of high nutritive value, and there is good medical treatment, health-care efficacy.The result of study in japanese food research center (Japan Food Research Laboratories) shows, in Sparassis crispa fruit body polyoses content enrich, every 100 grams containing beta glucan be 43.6 grams, higher than edible and medical fungis such as glossy ganoderma, Agricus blazei, Cordyceps militaris.Beta glucan in Sparassis crispa can improve body immunity and body hematopoiesis function, there is effect that is anticancer, anti-cancer, can prevent and improve the many diseases such as hypertension, hyperglycaemia because hematic acid, allergy and habits and customs produce, also have certain prevention and prohibition effect to some tumour, the mixed extract of Sparassis crispa and grifola frondosus can also Therapeutic cancer and acquired immune deficiency syndrome (AIDS) (JP 2003265139-A).Therefore, Sparassis crispa is health and the health food of a kind of " food and medicine consangunity ".
Because Sparassis crispa has good nutritive value and health-care efficacy, receive the very big concern of Chinese scholars and consumer in recent years gradually.Through studying for many years; Edible Fungus Research Institute, Fujian Academy of Agricultural Sciences can artificial cultivation Sparassis crispa; and achieve scale, factorial praluction (patent: a kind of Sparassis crispa industrialized cultivation medium formula and production technology; application number: 201010286462.6), but still adopt solid spawn in described production technology.The more traditional solid spawn of liquid spawn has many advantages, as: bacterial classification is with short production cycle, cost is low; The spawn activity produced is strong, purity is high; Inoculation is convenient, and after inoculation mycelium germination point many, spread rapidly, suitable edible mushroom large-scale planting etc.Therefore, liquid spawn is adopted to become the inexorable trend of edible fungus industrial development.
Pass through literature survey, current Sparassis crispa is cultivated bacterial classification used and is solid spawn, although there is the report about Sparassis crispa liquid fermentation technology, but be applied to cultivation and still have many limitation, as the optimal liquid medium that Jia Peipei etc. filters out, its hypha biomass is only 4.2g/L, and needs to add the nutriment such as honey powder, brewer's yeast in formula.By formula improvement, although Some Domestic patent improves a lot in hypha biomass, but still be more difficultly applied to large-scale planting.As patent [liquid fermentation culturing method of rare edible and medical fungi Sparassis crispa and special culture media thereof] (application number: 201110220578.4), medium needs the raw materials such as pine needle, and pine needle use before need through pre-treatment, be unfavorable for operation; And patent [a kind of wide leaf Sparassis crispa synthetic medium] (application number: the synthetic medium 201210370266.6) has into advantages such as distinguishing one from the other, steady quality, impurity are few, but be only suitable for orientation regulation and control and the metabolic flux analysis of the synthesis of Sparassis crispa metabolite, and the separation and Extraction of downstream metabolites.
In sum, about the research of Sparassis crispa liquid spawn, there are the following problems at present: 1, hypha biomass is low; 2, culture medium raw material source inconvenience, raw material supply is limited; 3, operation inconvenience, is unfavorable for large-scale production.Therefore, develop a kind of raw material sources extensively, handled easily, suitable Sparassis crispa large-scale production liquid spawn compounding method have great importance.
Summary of the invention
The present invention is directed to the shortcomings such as Sparassis crispa liquid nutrient medium cost is high, raw material sources are restricted, provide a kind of Sparassis crispa liquid spawn culture medium and cultural method, reduce production cost, enhance productivity.
Sparassis crispa liquid spawn culture medium optimization formula provided by the invention is as follows: glucose 0-145g/L, glutinous rice flour 0-70g/L, fish meal protein peptone 1-6g/L, KH
2pO
40-5g/L, MgSO
47H
2o 0-3g/L, initial pH 5-6.
More preferably, the formula of described medium is: glucose 10-145g/L, glutinous rice flour 35-60g/L, fish meal protein peptone 2-3g/L, KH
2pO
40-3g/L, MgSO
47H
2o 0-1.5g/L, initial pH 5.5-6.
It is convenient that this medium has raw material sources, simple operation and other advantages.
Sparassis crispa strain cultivation method of the present invention comprises the steps:
(1) Sparassis crispa liquid mother plants and prepares: first prepare liquid mother culture media, the formula of liquid mother culture media is: peeled potatoes 200g/L, glucose 20g/L, peptone 3g/L, initial pH 5-6; Then the test tube slant mother inoculating activation plants, and cultivation temperature 23-25 DEG C, shaking flask rotating speed 150rpm, cultivate 7-10 days, obtains liquid mother and plants;
