Embodiment Construction

[0019] In order to make those skilled in the art more aware of the technical solutions of the present invention and determine the technical effects of the present invention, preferred embodiments are now provided, but the implementation of the present invention is not limited to or dependent on the following preferred embodiments.

[0020] Separate expansion culture of bacteria

[0021] In the present invention, 5 kinds of strains of white rot fungus, Lactobacillus acidophilus, Trichoderma viride, Bacillus subtilis and Candida utilis are respectively used with corresponding 5 kinds of medium according to their respective characteristics: potato dextrose agar medium, MRS agar medium, Sabouraud agar medium, nutrient broth agar medium, and corn Tween 80 agar medium were used for expanded culture at a culture temperature of 26-37° C. for 3 days to obtain a first-generation strain. The specific medium formula is shown in Table 1:

Abstract

The invention relates to a microbial fermentation technology and particularly relates to a microbial agent for high-efficiency straw fermentation. The microbial agent comprises white-rot fungus, lactobacillus acidophilus, trichoderma viride, bacillus subtilis and candida utilis, and is prepared from such five microbial bacteria as the white-rot fungus, the lactobacillus acidophilus, the trichoderma viride, the bacillus subtilis and the candida utilis. the microbial agent can be used for the high-efficiency fermentation of straw feed so that the straw feed contains a large amount of living biological cells, decomposition enzymes and other active components and the utilization rate of the straw feed is improved effectively. The microbial agent has the practical significance of solving the problem of environment pollution, has the actual application value of increasing the content of protein in the straw feed and the nutritional value of the straw feed and creates a good precondition for the utilization of straw as a resource.

Description

technical field [0001] The invention relates to biodegradation technology, in particular to high-efficiency straw fermentation microbial bacterial agent. Background technique [0002] Straw refers to the general term for mature crop stems, leaves and ears. Usually refers to the remaining parts of wheat, rice, corn, potatoes, oilseeds, cotton, sugar cane and other crops after harvesting seeds. Straw resources are abundant and are the main source of roughage for herbivorous livestock. [0003] However, the main components of straw are lignin, cellulose and hemicellulose, and the digestibility of untreated straw in herbivorous livestock is low. Microbial treatment technology is a green and environmentally friendly technology to improve the utilization rate of straw digestion. After microbial treatment, straw lignin is reduced, palatability is good, and digestibility is high. At the same time, you can avoid straw burning to pollute the air and waste resources. Therefore, the...
