Problems solved by technology

[0004] At present, most of the commonly used microbial preparations for purifying water use a single strain or a combination of two or three strains. The number of viable bacteria in the preparation is low, and it cannot comprehensively and effectively improve the quality of aquaculture water. Microbial agent, comprehensively improve the farming status

Abstract

The invention aims to provide a production method for a compound microbial preparation for aquatic products. The production method comprises the following steps: respectively carrying out high-density liquid fermentation on strains of bacillus cereus, bacillus licheniformis, halophilic pseudomonas, lactobacillus acidophilus, rhodococcus erythropolis, rhodopseudomonas palustris and enterococcus faecium to obtain ultra-concentrated bacterium powder; and then preparing according to a ratio to obtain the compound microbial preparation. The production process is simple in process, is applicable to most existing fermentation processes and equipment and is good for being popularized and applied in a large scale.

Description

technical field [0001] The invention relates to the technical field of microorganism application, in particular to a production method of a composite microorganism preparation for aquatic products. Background technique [0002] Usually in the natural state, the indigenous bacteria in the water body can maintain the normal material circulation of the water body through self-purification. However, with the development of high-density aquaculture, the organic load in the aquaculture water has greatly exceeded the self-purification ability of the original flora. The organic matter that has not been effectively utilized has become the largest pollution source in the water body, consumes a large amount of dissolved oxygen, causes oxygen debt in the water body, and then inhibits the complete oxidation of organic matter, forming a large number of incomplete oxidation intermediates, and these incomplete oxidation products are often It is the most harmful toxic substance in aquacultu...
