Preparation method of compound microbial agent for aquaculture

Abstract

The invention discloses a preparation method of a compound microbial agent for aquaculture. The preparation method is characterized by comprising steps as follows: S1, preparation of an inoculation medium; S2, preparation of a culture medium; S3, respective domestication culture; S4, mixed domestication culture; S5, preparation of the compound microbial agent for aquaculture. Adopted nano soybeanmeal has high nutritional value and is matched with straw powder to increase the content of cellulose, a matrix contains comprehensive nutritional ingredients, and growth of probiotics is facilitated.Through multi-round domestication breeding, the microbial agent has high survival rate and content of flora and high bioactivity and adaptability and has the characteristics of efficiency, stabilityand rapid propagation, harmful substances are decomposed by probiotics in a disease-resistant manner, healthy growth of aquatic products is enhanced, harmful substances such as ammonia, nitrogen and the like in water are degraded, the removal rate reaches 97% or above, breeding of algae can be inhibited, bacterial florae in the water can be rapidly recovered and balanced, the water is purified, the environment is improved, and defects in the prior art are overcome.

Description

technical field [0001] The invention relates to the technical field of biological bacterial agents, in particular to a method for preparing aquaculture composite bacterial agents. Background technique [0002] The prior art aquaculture compound bacterial agent is prepared by a conventional fermentation process, the fermentation process is poorly controllable, the survival rate and content of beneficial bacteria are low, and the biological activity and adaptability are poor. [0003] The present invention adopts soybean powder with broken cell wall to have high nutritional value, and the nano-fine crushing of broken cell wall can fully maintain the biological activity of trace elements in the raw material, enhance the nutritional diversity of the matrix, add straw powder to increase the cellulose content, and increase the nutritional value of the matrix. The ingredients are comprehensive and conducive to the growth of probiotics. Multiple rounds of domestication and reproduc...
