Description

A kind of culture medium and cultural method of promotion flat mushroom liquid mycelia fast-growth
Technical field
The invention belongs to fungus growing technique field, more particularly to a kind of training of promotion flat mushroom liquid mycelia fast-growth Support base and cultural method.
Background technology
Liquid spawn technology is Edible Fungi, the technology especially commonly used in edible fungus industrial production, and it, which has, is permitted Many advantages:One is that production technology simplifies, and point without parent species, original seed and cultigen, technique is simple, saves time cost;Two are Strain purity is higher, be bacterial contamination it is small, germination point disperse, bacterium germination is fast;Three be that speed is fast, cost is low for inoculation;Four be production week Phase is short, and fruiting is neat, is adapted to large-scale production, no seasonal limitation;Five be to be convenient for changing strain, and the replacement cycle is short.
Current factorial praluction liquid spawn is applied to the Pollution In Edible Mushroomss factory metaplasias such as asparagus, pleurotus eryngii, mushroom In production, and achieve significant economic benefit.Compare other edible fungus varieties, and the application of flat mushroom liquid spawn is less, a side The production of face and current flat mushroom is that seasonal cultivation production is relevant mostly, another aspect, continuous with people's living standard Improve, the year-round supply demand for flat mushroom product is continued to increase, and the trend of flat mushroom factorial praluction is irreversible, therefore flat mushroom The production of liquid spawn is particularly important.Make strain fast-growth within a short period of time and using simple method, concern work The reduction of factory's operating cost.Strain cultivation influence factor is a lot, such as degree of purity of oxygen content, air etc., culture The formula of base is also one of mostly important influence factor.
In summary, the problem of prior art is present be:In production, flat mushroom liquid spawn applies less, especially work Almost do not applied under factory's production model.The formula of existing culture medium is more complicated simultaneously, and formula contained substance species is more, Manufacture craft is also more complicated.Prior art can not make flat mushroom liquid spawn fast-growth within a short period of time, it is impossible to effectively drop The reduction of low batch production operating cost.
The content of the invention
The problem of existing for prior art, the invention provides a kind of culture of promotion flat mushroom liquid mycelia fast-growth Base and cultural method.
The present invention is achieved in that a kind of cultural method of promotion flat mushroom Mycelia fast-growth, the rush The cultural method for entering flat mushroom Mycelia fast-growth comprises the following steps:
Step one, strain activation and culture:Low temperature or the flat mushroom strain of liquid nitrogen preservation are taken out, potato-grape is seeded in Activation culture is carried out on sugar-agar (PDA) plating medium;Then beaten with card punch on flat board and take fungus block and be inoculated with fungus block In the flat board center culture containing PDA culture medium;Beaten again with identical card punch and take fungus block;
Step 2, cultivates matrix manufacturing:Peeled potatoes are cut into small pieces, and are boiled in the pot for being put into the deionized water boiled;So After filter, glucose is added in filtrate, is allowed to be completely dissolved;Deionized water constant volume is used, is stirred and evenly mixed standby;Then in triangle The culture medium containing glucose is added in bottle;Peanut oil, ventilated membrane sealing are added in triangular flask;Sterilizing;It is cooled to after room temperature, It is placed in superclean bench;Beaten with card punch on the mycelia flat board of culture and take multiple strain blocks, then access is free of agar In Potato-dextrose-agar (PDA) fluid nutrient medium, constant-temperature table, shaken cultivation;
Step 3, hypha biomass is determined:Cultured mycelia is filtered, is then washed with deionized, is then dried to Constant weight.
Further, step one strain activation and culture, is specifically included:
4 DEG C of low temperature or the flat mushroom strain of liquid nitrogen preservation are taken out, the training of Potato-dextrose-agar (PDA) flat board is seeded in Support and 25 DEG C of activation culture 8d~10d, repetition of activation 2 times are carried out on base;
Then beaten with diameter 5mm card punch on flat board and take fungus block and be seeded in fungus block flat containing PDA culture medium Plate center, 25 DEG C of culture 10d;Beaten again with identical card punch and take fungus block.
Further, the step 2 culture matrix manufacturing, is specifically included:
Peeled potatoes 200g, is cut into 0.5cm~1cm fritter, is put into the pot for filling the deionized water that 800mL boils In, boil 10min~15min;
Then with 4 layers of filtered through gauze, 20g glucose is added in filtrate, is allowed to be completely dissolved;Use deionized water constant volume To 1000mL, stir and evenly mix standby;
Then 100mL above-mentioned culture medium is added in the triangular flask of 250mL capacity;Quality is added in above-mentioned triangular flask The peanut oil of volume ratio (w/v) 0.1%~1.0%, to be not added with peanut oil as control, ventilated membrane sealing;121 DEG C of sterilizings 30min;
It is cooled to after room temperature, is placed in superclean bench;Put down with diameter 5mm card punch in culture 8d~12d mycelia Beaten on plate and take 10 strain blocks, then accessed in fluid nutrient medium, be placed in 25 DEG C of constant-temperature table 150rpm shaken cultivations 5d.
Further, the step 3 hypha biomass is determined, and is specifically included:
By cultured mycelia with 4 layers of filtered through gauze, 3~5 times are then washed with 100mL~200mL deionized water, so Dried to constant weight afterwards at 50 DEG C.
Another object of the present invention is to provide a kind of culture medium for promoting flat mushroom Mycelia fast-growth by horse Bell potato 200g, glucose 20g, distilled water 1000mL and in w/v ratios peanut oil 0.1%~1.0% constitute constitute.
Advantages of the present invention and good effect are:
Compared with prior art, the present invention is added after peanut oil, mycelia can be made dark white, mycelia branch increases, can Promote mycelia fast-growth, dry mycelial weight is not than adding the high by 109.02%~331.96% of peanut oil processing.
