Embodiment 1

[0065] A kind of preparation method of photosynthetic bacteria agent is as follows:

[0066] a), seed liquid preparation

[0067] On a sterile operating table, inoculate Rhodopseudomonas palustris into the seed medium, and cultivate the bacteria in a shaker at 30°C and 180rpm / min under the light of 2400lux incandescent lamp until the concentration of the bacteria reaches 10 8 CFU / mL, to obtain Rhodopseudomonas palustris seed solution;

[0068] b), fermentation culture

[0069] Add 5mL of Rhodopseudomonas palustris seed liquid to the fermentation medium, cultivate it in a shaker at 30°C and 180rpm / min under the light of a 2400lux incandescent lamp, and detect the number of bacteria in the fermentation bacteria until the number of bacteria reaches 10 10 When the CFU / mL is reached, the fermentation is stopped to obtain the photosynthetic bacteria agent.

[0070] The pH of the seed medium is 7.0, containing the following substances: 2 g of ammonium chloride, 5 g of sodium aceta...

Abstract

The invention discloses an aquaculture water cleaning agent and a preparation method thereof. By culturing photosynthetic bacteria, denitrifying bacteria and bacillus in a culture medium containing porous SiC ceramic particles, microorganisms are enriched on the porous SiC ceramic particles to prepare the aquaculture water cleaning agent. Compared with the prior art, the prepared aquaculture watercleaning agent has good effects on water purification and disease prevention for aquaculture water.

Description

technical field [0001] The invention relates to a microbial water purification treatment technology, in particular to an aquaculture water purification technology. Background technique [0002] In aquaculture water, the water micro-ecosystem is composed of pathogenic microorganisms, conditional pathogenic microorganisms and non-pathogenic microorganisms. These microorganisms cooperate with each other and are in a relatively stable dynamic equilibrium state. However, the high density of breeding and the addition of artificial bait make the breeding ecosystem an unstable ecosystem, and fluctuations in any link may cause ecological imbalance. Once the balance is broken, harmful bacteria will transform into pathogenic bacteria. According to incomplete statistics, from 2005 to 20015, the average annual loss of aquaculture diseases in my country reached tens of billions of dollars. The control of aquaculture diseases in my country is mainly based on drug prevention and control. I...
