Abstract
The invention discloses a preparation method of a culture substrate of coprinus comatus. The culture substrate is prepared by mixing 30-60% of smashed wood chips, 20-40% of secondary smashed straw hydrolyzed by cellulase, 10-15% of secondary smashed wood chip hydrolyzed by laccase, 5-10% of urea and 1-5% of gypsum powder. According to the preparation method of the culture substrate of coprinus comatus, provided by the invention, straw waste is fully utilized, and the cultured coprinus comatus is crisp and refreshing in taste.
Description
Technical field
The invention belongs to mushroom cultivation field.
Background technology
In mushroom cultivating process, the main two problems one considered is the level of growth of mushroom itself, another is the control of miscellaneous bacteria and insect pest in mushroom cultivating process, the control of these two aspects and balance are except relying on growth conditions, as outside the regulating and control of temperature, humidity etc., also depend on the selection of culture medium, not only if culture medium is beneficial to the growth of mushroom itself but also pole is beneficial to the breeding of miscellaneous bacteria and insect, then not favourable to the cultivation of mushroom.
Summary of the invention
The object of the present invention is to provide one can both meet Coprinus comatus well to grow, obtain the Coprinus comatus that mouthfeel is crisp and refreshing, the preparation method of the culture medium that can effectively suppress varied bacteria growing to be bred again.
Technical scheme of the present invention is as follows: the preparation method of the culture medium of a kind of Coprinus comatus, comprises the following steps:
1) by mass content be 20 ~ 40% crushing straw carry out high-temperature sterilization, thereafter use dilute acetic acid solution regulate its pH value to be 4 ~ 6, add at 30 ~ 40 DEG C cellulase reaction 6 ~ 12h, obtain secondary crushing straw, all operations process is all aseptically carried out;
2) by mass content be 10 ~ 15% wood fragments bits carry out high-temperature sterilization, thereafter use dilute acetic acid solution regulate its pH value to be 4 ~ 6, at 30 ~ 40 DEG C, add laccase reactions 5 ~ 8h, obtain secondary wood fragments bits, all operations process is all aseptically carried out;
3) by mass content be 30 ~ 60% wood fragments bits with 1% ~ 5% terra alba carry out high-temperature sterilization, consider to be worth doing with described secondary wood fragments thereafter, described secondary crushing straw and 5% ~ 10% urea mix mutually, namely obtain culture medium, mixing process is aseptically carried out.
Its preferred embodiment is: described cellulase be selected from circumscribed beta-glucanase, Endo-β-glucanase and beta-glucosidase one or more.
Cellulase herein also can select the complex class cellulase of commercial type.
Its another preferred embodiment is: described crushing straw is the crushed material of corn or wheat stalk.Its another preferred embodiment is: described wood fragments bits are the limb crushed material of fruits trees.
The trees of growth fruit that refer to of said fruits trees herein, as pear tree, Japanese plum, peach, apple tree, apricot etc.
Usefulness of the present invention is:
1) Appropriate application waste straw, is beneficial to circulation and the regeneration of resource;
2) culture medium prepared can grow and obtain the crisp and refreshing Coprinus comatus of mouthfeel;
3) this culture medium can suppress the growth of other miscellaneous bacteria and insect, obtains the Coprinus comatus of good quality.
Embodiment
Embodiment 1
1) by mass content be 15% apple tree wood fragments bits carry out high-temperature sterilization after add dilute acetic acid solution and regulate its pH value to be 6, at 35 DEG C, add thereafter quality is obtain secondary wood fragments bits after the laccase reactions 10h of wood fragments bits quality 8%;
2) by mass content be 20% wheat crushing straw carry out high-temperature sterilization after add dilute acetic acid solution and regulate its pH value to be 5, at 30 DEG C, add thereafter quality is obtain secondary crushing straw after the compound cellulose enzyme reaction 8h of crushing straw quality 10%;
3) by mass content be 50% apple tree wood fragments bits, mass content be 5% terra alba carry out high-temperature sterilization, be the urea of 10% with mass content thereafter, and above-mentioned secondary wood fragments bits fully mix with secondary crushing straw, namely obtain culture medium;
Said process all aseptically carries out.
Embodiment 2
1) by mass content be 15% pear tree wood fragments bits carry out high-temperature sterilization after add dilute acetic acid solution and regulate its pH value to be 6, at 35 DEG C, add thereafter quality is obtain secondary wood fragments bits after the laccase reactions 6h of wood fragments bits quality 6%;
2) by mass content be 35% corn crushing straw carry out high-temperature sterilization after add dilute acetic acid solution and regulate its pH value to be 5, at 40 DEG C, add thereafter quality is obtain secondary crushing straw after the circumscribed beta-glucan enzyme reaction 10h of crushing straw quality 8%;
3) by mass content be 40% pear tree wood fragments bits, mass content be 5% terra alba carry out high-temperature sterilization, consider to be worth doing with above-mentioned secondary wood fragments thereafter with secondary crushing straw, and mass content be 5% urea fully mix, namely obtain culture medium, said process aseptically carries out.
