Problems solved by technology

Edible fungi can be cultivated by using these waste materials as culture materials for edible fungi, but because of their low nutritional content, the biotransformation rate is low
[0004] Cassava, Euphorbiaceae, cassava genus, scientific name Manihot esculenta Crantz, is an agricultural product rich in subtropical regions of my country. When producing alcohol with fresh cassava or dried cassava chips, after saccharification, fermentation, distillation, and extraction of ethanol, the distiller's grain waste produced Liquor is an environmental pollution source that alcohol production enterprises have not been able to effectively solve. In severe cases, the cost of pollution control is too high, resulting in production suspension
A reasonable treatment plan has not been found so far, and there has been no report on the use of cassava distillers grains for the cultivation of edible fungi

Embodiment 1

[0021] Cultivation of abalone mushroom:

[0022] Compost: 95% cassava distiller's grains (percentage by weight, the same below), 5% lime powder.

[0023] Cultivation process: After the cassava is fermented to produce alcohol, the water content of the centrifuge is separated from solid and liquid to reach 75-80%, and the water content is further dehydrated by a filter press to reach 60%. Add lime powder to the above-mentioned cassava distiller's grains, and adjust the water content to 60%. At the same time, mix 5% oyster mushroom seeds by the weight of the above compost to sow and pack them into bags. After the bags are sealed, they are stacked on the culture rack. After the silk is all overgrown, mushroom buds can be seen in 5 to 7 days after opening the bag, and can be harvested in another 5 to 7 days. The second flush mushroom can be harvested at an interval of 10 to 15 days, and 5 to 6 flush mushrooms can be produced. The entire cultivation cycle is 80 ~90 days. The envir...

Embodiment 2

[0025] Cultivation of abalone mushroom:

[0026] Ratio of compost: cassava distiller's grains 80%, wood bran 15%, lime powder 5%.

[0027] Cultivation process: the pre-treatment of distiller's grains is the same as in Example 1. Mix wood bran and lime powder with a mixer, add water to sterilize, adjust the water content to 65%, and then mix it with cassava distiller's grains. At the same time, add 5% oyster mushroom strains by the weight of the above-mentioned compost to mix and sow, pack into bags, and seal the mouth of the bag. Stacked on the culture rack, after 28 to 30 days, the mycelium will be completely covered with the material bag, and mushroom buds will be visible after 5 to 7 days after opening the bag, and the mushroom can be harvested after 5 to 7 days, and the second lake can be harvested after 10 to 15 days Mushrooms, a total of 4 to 5 tide mushrooms can be produced. The whole cultivation period is 70-80 days. The mycelial growth period is one week earlier th...

Embodiment 3

[0029] Cultivation of anchovy mushrooms:

[0030] Ratio of compost: cassava distiller's grains 80%, bagasse 14%, lime powder 6%.

[0031] Cultivation process: the pre-treatment of distiller's grains is the same as in Example 1. Take bagasse and lime powder and mix with water, adjust the water content to 65%, mix it with cassava distiller's grains after stirring evenly, and mix 5% of the weight of the above-mentioned compost at the same time. On the culture rack, after 18-20 days, the mycelium is completely covered with the material bag, and the mushrooms can be produced. After the mushroom buds appear, they can be harvested after 5-7 days. The second lake mushroom can be harvested at an interval of 5-6 days. ~6 tidal mushrooms. The whole cultivation period is 50-60 days. In the cultivation and management from sowing to picking mushrooms, the environmental conditions required for each stage of the growth of Pterata mushrooms are basically the same as those cultivated with co...

Abstract

A method for culturing the edible funguses by use of the cassava dregs generated by preparing alcohol is disclosed. Its advantages are no need of sterilizing step, low energy consumption and cost, and high productivity and yield.

Description

technical field [0001] The invention belongs to the technical field of edible mushroom cultivation. Background technique [0002] At present, the culture materials used in the cultivation of edible fungi in my country mainly include agricultural and forestry by-products such as mushroom sawdust, cottonseed hulls, corn cobs, bagasse, peanut shells, wheat bran, urea, and sugar. Among these composts, some raw materials contain too low nutrients and high lignin content, the mycelium is difficult to absorb the required nutrients, and the whole growth cycle is slow; some raw materials are too expensive, resulting in the cultivation cost of edible fungi. It is very high, and these conventional culture materials need to be sterilized because they are infected by miscellaneous bacteria, which increases the energy consumption and labor costs of cultivating edible fungi, limits the development of large-scale standardized production of domestic edible ...
