Embodiment 1

[0015] The above-mentioned microorganisms are respectively fermented in high-density liquid, and the post-treatment technology of the fermentation process is used to make the spore content as high as 10 10 -10 12 CFU / g ultra-concentrated bacteria powder. Then the super-concentrated bacteria powders were mixed and prepared according to the following proportions: 30% of Bacillus subtilis, 10% of Bacillus licheniformis, 20% of Bacillus cereus, 3% of Pseudomonas aeruginosa, 2% of Rhodococcus red city, pseudohalophilus Monomonas 5%, Rhodopseudomonas palustris 10% and Enterococcus faecium 20%.

[0016] The prepared compound preparation is packaged with water-soluble materials.

Embodiment 2

[0019] The above-mentioned microorganisms are respectively fermented in high-density liquid, and the post-treatment technology of the fermentation process is used to make the spore content as high as 10 10 -10 12 CFU / g ultra-concentrated bacteria powder. Then the super-concentrated bacterial powders were mixed according to the following proportions: 35% of Bacillus subtilis, 10% of Bacillus licheniformis, 10% of Bacillus cereus, 2% of Pseudomonas aeruginosa, 5% of Rhodococcus red city, halophilic pseudomonas 8%, Rhodopseudomonas palustris 10% and Enterococcus faecium 20%.

[0020] The prepared compound preparation is packaged with water-soluble materials.

Embodiment 3

[0023] The above-mentioned microorganisms are respectively fermented in high-density liquid, and the post-treatment technology of the fermentation process is used to make the spore content as high as 10 10 -10 12 CFU / g ultra-concentrated bacteria powder. Then the super-concentrated bacterial powders were mixed and prepared according to the following proportions: 20% of Bacillus subtilis, 10% of Bacillus licheniformis, 20% of Bacillus cereus, 3% of Pseudomonas aeruginosa, 2% of Rhodococcus red city, Monomonas 10%, Rhodopseudomonas palustris 10% and Enterococcus faecium 25%.

[0024] The prepared compound preparation is packaged with water-soluble materials.

Abstract

The invention discloses a mariculture water body purification composite microbial preparation, and belongs to the technical field of water body purification. The contents of component concentrated bacterial powders of the composite microbial preparation comprise 20-50% of bacillus subtilis, 5-15% of bacillus licheniformis, 10-30% of bacillus cereus, 1-5% of pseudomonas aeruginosa, 1-5% of rhodococcus erythropolis, 5-10% of pseudomonashalophila, 5%-15% of rhodopseudomonas palustris, and 15%-40% of enterococcus faecium. After the bacterial powders are mixed in proportion, packaging is carried out by adopting a water soluble material. The composite microbial preparation is put into a mariculture water body, enables dominant strains to be reproduced rapidly, allows culture pond redundant remnant feeds, feces, animal and plant dead bodies and other organic pollutants to be decomposed by active and abundant enzyme systems, and can significantly reduce the contents of ammonia nitrogen and nitrite in the culture water body.

Description

technical field [0001] The invention relates to a water body purification technology, in particular to a microbial compound preparation for seawater culture water body purification. Background technique [0002] At present, due to the continuous development of the development and utilization of marine resources, mariculture has occupied an increasingly important position in my country's aquaculture. However, due to the rapid development of marine aquaculture, the quality of water resources has declined, and the pollution of the offshore environment has intensified, especially in high-density and intensive aquaculture. Excessive use of bait, excessive use of chemical drugs, and discharge of aquaculture excrement have greatly increased the content of nitrogen and phosphorus nutrients and toxic substances such as nitrite and hydrogen sulfide in seawater. The eutrophication of seawater caused by the increase of the content of these substances is bound to bring large-scale damag...
