Embodiment Construction

[0019] (a) Mycelium culture method

[0020] The agar medium formula that the present invention adopts:

[0021] (1) Wheat bran juice sucrose medium: 50-100g wheat bran, 20g sucrose or glucose, 20g agar, 1000mL water, natural pH.

[0022] (2) Pine needle juice glucose-peptone medium: 50-100g pine needles, 20g glucose or sucrose, 2-3g peptone, 20g agar, 1000mL water, natural pH.

[0023] (3) Potato enriched medium: 200g potato, 20g sucrose or glucose, 3-5g peptone, 2g yeast powder, 20g agar, 1000mL water, natural pH.

[0024] Liquid medium: Agar is not added to the above recipe.

[0025] Cut wheat bran, pine needles, potatoes and other plant materials into small pieces, add 1200-1300mL of water, boil for 20min, filter, and remove 1000mL of filtrate. Add agar to the filtrate and heat to dissolve the agar completely, then add other ingredients, heat to dissolve, and constant volume. Divided into test tubes and triangular flasks, sealed and sterilized, cooled and stored for 24 ...

Abstract

The invention relates to a new strain of edible fungus, belonging to the technical field of edible fungus development and utilization. The new grey variant strain of edible fungus with red pleurotus: Pleurotus djamor (Rumph.: Fr.)Boedijn, is the new strain of edible fungus selectively bred through single spore cross breeding and has the number No.1933 in CGMCC (China General Microbiological Culture Collection Center). The strain is characterized in that the color of sporophore is stable grey white, the whole sporophore is pure and transparent, the cellulose content is 5-12%, and the strain has favorable mouth feel and is used for producing the edible fungus in the high temperature season. Mycelium grows very fast and has strong ability in fighting bacteria and also has developed aerial hyphae. The hypha has clamp connection and the growth temperature of 3-45 DEG C; the temperature of sporophore differentiation is 18-35 DEG C, and the new grey variant strain is typical high temperature edible fungus. Straws, saw dust, bran, and the like are selected as cultivation materials. The edible fungus is cultivated in March to November. Cultivation materials produced in scale do not need high pressure or normal pressure sterilization, and the sporophore output is 15-25%. The strain is newly selected and bred edible fungus and has application value in the edible fungus field and ornamental fungus field.

Description

(1) Technical field [0001] The invention relates to an off-white Pleurotus mutated edible fungus strain, which belongs to the technical field of development and utilization of edible fungal resources. The strain is a newly selected edible fungus and ornamental fungus. (2) Background technology [0002] There are relatively few resources of high-temperature edible fungi. Oyster mushrooms include oyster mushrooms, Pleurotus spp., Pleurotus elm, and common red Pleurotus. Pleurotus ostreatus is a rare fungus that has no commercial production at home and abroad and few research reports. It has strong anti-miscellaneous bacteria ability, wide adaptability to environment, resistance to extensive cultivation, fast growth rate of mycelia, strong decomposition ability, high yield of fruiting bodies, and high commercial development prospects. However, the cellulose content of the fruiting body of Pleurotus ostreatus is very high. Generally, the cellulose content of Pleurotus ostreatu...
