Pleurotus eryngii culture medium capable of realizing high efficiency utilization of cellulose, and preparation method thereof

Abstract

The invention discloses a pleurotus eryngii culture medium capable of realizing high efficiency utilization of cellulose, and a preparation method thereof. The pleurotus eryngii culture medium is prepared from, by weight, a high-yield cellulase bacteria solution, polyvinyl alcohol, 2 to 4wt% of a CaCl2 solution, sodium alginate, 2 to 5wt% of a NaOH solution, bamboo shoot shell, wheat bran powder, soy peptone, agar powder, cinnamomum camphora saw dust, scirpoides holoschoenus, cassava slag, coconut residue, coal gangue, and an appropriate amount of water. The pleurotus eryngii culture medium contains a large amount of fiber raw materials such as saw dust and scirpoides holoschoenus, so that decomposition utilization is difficult to realize under general conditions. According to the preparation method, cellulase bacteria is coated with a coupled product of sodium alginate and calcium chloride, and is absorbed by the pleurotus eryngii culture medium, so that the pleurotus eryngii culture medium can be taken as a culture medium for a long term, utilization of cellulose by pleurotus eryngii is realized after decomposition of cellulose; the added ore is subjected to calcining firstly science calcining is beneficial for oxidation of mineral elements, and the mineral elements are decomposed into ions with time passing, so that the content of inorganic elements of the pleurotus eryngii culture medium is increased.

Description

technical field [0001] The invention belongs to the technical field of edible fungus culture medium, and in particular relates to a pleurotus eryngii compost that utilizes cellulose efficiently and a preparation method thereof. Background technique [0002] Edible fungi generally include fruiting bodies and mycelia, which are composed of eukaryotic microorganisms. Under a suitable growth environment such as sufficient nutrition and no restrictions on the individual, the individual will multiply rapidly, resulting in a substantial increase in the number, but when the number of fungi When it is increased to a certain amount, a mycelium composed of fungi will be formed. The dense mycelium is restricted by each other, and the directional formation of the fruiting body primordium is formed by the dense mycelium, which will later produce spores for sexual reproduction. Organs, while the mycelium is composed of tube-shaped cells that absorb nutrients, presenting a fluffy shape with...

Problems solved by technology

[0003] The main problem of the edible fungus culture medium at this stage is that the medium is used less frequently, and many mediums will be discarded after being used twice or even once. The reason is that the nutrients of the medium are difficult to maintain the normal state of the next new fruiting body Growth is mainly due to the lack of nitrogen and carbon sources, and doing so will greatly increase the amount of labor, increase the use of raw materials, and increase the consumption of additional resources. At the same time, it is found that there are still residual There are a lot of nutrients. The main sources of nutrients for the medium used by eukaryotic microorganisms are soluble carbohydrates, sugar, starch and a small amount of low-molecular vitamins. Due to different functions, fungi can rarely use wood chips and cottonseed as raw materials. Husks, rice husks, corn cobs and other raw materials mainly composed of cellulose, resulting in a large amount of unused cellulose components in the culture medium waste, how to use this part of nutrition can greatly increase the use frequency of edible fungus culture medium and reduce Additional investment costs

Cellulase can be hydrolyzed to glucose under their synergistic action, but the significant disadvantages of cellulase are that cellulase has poor stability, short life and low single enzyme activity
