Method for fermenting and producing microbial agent by utilizing cassava alcohol residues

Abstract

The invention discloses a method for fermenting and producing a microbial agent by utilizing cassava alcohol residues, belonging to the technical field of microbial agent production, so that the high-quality microbial agent is produced, and meanwhile, the pollution caused by the cassava alcohol residues also can be treated, and the cyclic economy benefit for the cassava alcohol industry is realized. The method for fermenting and producing the microbial agent by utilizing the cassava alcohol residues comprises the following steps of: mixing the cassava alcohol residues, humic acid decomposed coal or grass carbon and dry straw ash, wherein the water content of the mixture is controlled to be 33%-70%; adding the microbial agent being 2% of the mass of the mixture into the mixture, stirring uniformly and quickly, packing the mixture into a seal bag, carrying out anaerobic fermentation for 10 days at the normal temperature in the southern of China, thereby producing the microbial agent with the number of effective viable bacteria greater than or equal to 0.3billion / gram (higher than the national standard by 0.2 billion / gram). According to the method, the cost is low; the operation is simple; the product quality is high; the cassava alcohol residues are changed into wealth from waste, and effective resource utilization is realized; not only is the environment pollution problem solved, but also high environment-friendly expanse is saved for cassava alcohol enterprises, and meanwhile good economic benefit is brought; an enclosed biological circle of the cassava alcohol production is formed; and the cyclic economy benefit is created.

Description

technical field [0001] The invention belongs to the technical field of microbial bacterial agent production, and relates to a method for producing microbial bacterial agent by fermenting cassava alcohol residue. The method of the invention also solves the resource waste problem that the cassava alcohol residue is not easily utilized and the environmental pollution problem caused by the microbial bacterial agent. Background technique [0002] Cassava alcohol residue is waste from the production of alcohol from cassava and tapioca starch residue. The starch content of dried cassava exceeds 80%, which is an ideal raw material for the production of alcohol. With the development of the cassava alcohol industry, a large amount of cassava alcohol residue is produced. Due to the high water content of cassava alcohol residue, low nutritional value such as protein, and high crude fiber content, it is difficult to be utilized. At present, except for a very small part that is used to f...
