A kind of solid starter for fermenting peanut straw

Abstract

The invention relates to a solid starter for fermenting peanut stalks, which can effectively solve the problems of inconvenient storage for liquid fermentation, easy aging of strains, loss of vitality, high technical difficulty, unstable output, and large investment. The technical solution is: The solid leavening agent is made from five kinds of microorganisms, bran and corn flour. The five kinds of microorganisms are Trichoderma viride powder, Phanerochaete chrysosporium powder, Candida utilis powder, Bacillus subtilis powder and Enterococcus faecalis powder, the number of effective viable bacteria contained in every 1g of solid starter is 5×10 9 -20×10 9 cfu, every 1g of solid starter contains 20-45% of bran and 10-30% of corn flour. Mix the above raw materials together and stir evenly. The peanut straw solid starter of the present invention can increase the crude protein content in peanut straw , reduce the cellulose content, and change the palatability and feed utilization rate of peanut straw, which is an innovation in peanut straw starter.

Description

technical field

[0001] The invention belongs to the field of biotechnology, in particular to a solid starter for fermenting peanut stalks. Background technique

[0002] Peanut is one of the five important oil crops and one of the important economic crops in my country. Henan Province is the largest peanut producing province in the country, with a planting area of ​​more than 15 million mu, a total output of more than 4.5 million tons, and a peanut straw output of 3 to 4 million. Tons, abundant yield, peanut straw texture is soft and rich in nutrients, its crude protein is about 6% to 20%, crude fat is about 2% to 3%, carbohydrate (mainly crude fiber) is about 46% to 48%. Due to the large amount of cellulose contained in peanut straw, the digestion and utilization rate of livestock and poultry is low, which affects the production performance of livestock and poultry, and will hinder the contact of other nutrients with various enzymes, reducing the digestion and utilization rat...
