Compound bacterium enzyme preparation for improving water quality as well as preparation method and application of compound bacterium enzyme preparation

Abstract

The invention relates to a compound bacterium enzyme preparation for improving water quality and further relates to a preparation method and application of the compound bacterium enzyme preparation. The compound bacterium enzyme preparation comprises the following components: bacillus subtilis, an alkaline protease, a neutral protease, an amylase, a saccharifying enzyme, glucose oxidase and carriers, wherein the bacillus subtilis belongs to one of products produced by liquid fermentation and solid fermentation; the alkaline protease and neutral protease belong to one of products produced by fermentation of bacillus subtilis and genetic engineering yeast; the amylase belongs to one of alpha amylase, beta amylase and gamma amylase; the saccharifying enzyme is selected from one of products produced by fermentation of aspergillus and genetic engineering yeast; and the glucose oxidase is selected from one of products produced by fermentation of aspergillus niger and blue mould. The compound bacterium enzyme preparation disclosed by the invention can achieve the effects of assisting decomposition of residual feeds, excrements and other organic matters in aquaculture ponds, improving the water quality and the substrate of the pond, reducing the content of ammonia nitrogen and nitrite in aquatic water and improving the water transparency.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and relates to a water quality improving agent, in particular to a compound bacterial enzyme preparation for improving water quality, and also relates to a preparation method and application of the compound bacterial enzyme preparation. Background technique [0002] At present, in the process of aquaculture, water quality is the main factor that determines the production of aquaculture. The main factor causing the deterioration of water quality is that a large amount of residual bait and feces accumulate at the bottom of the pond, and water microorganisms cannot quickly utilize and convert the residual bait and feces into nutrients needed for algae growth. With the eutrophication of the water body, the algal phase of the water body has gradually changed to harmful algae such as dinoflagellates, euglena, and cyanobacteria. At the same time, algae respiration at night will rapidly reduce the di...

AI Technical Summary

Problems solved by technology

[0004] At present, aquaculture water quality improver microorganisms or enzyme preparation granules generally rely on two methods: disc granulation and extrusion granulation: the disc granulation drying particle size is larger, the drying process is simple, and the temperature control is uneven and relatively difficult. High, the loss of the enzyme activity of the strain is relatively large, and the general loss rate reaches about 50%. It can reach above 70 degrees, and it also caused a great loss to the enzyme activity of the bacteria
