Aquaculture photosynthetic bacteria and production process thereof

Abstract

The invention discloses aquaculture photosynthetic bacteria and a production process thereof. The prepared industrial pure water replaces the tap water used in the prior art, an ultraviolet disinfection and sterilization process is adopted, and chemical agents such as sodium hypochlorite and sodium thiosulfate are avoided. The aquaculture photosynthetic bacteria realize thorough disinfection, improve the production environment of the photosynthetic bacteria and improve the quality of the aquaculture photosynthetic bacteria.

Description

technical field [0001] The invention belongs to a production process of photosynthetic bacteria, and in particular relates to a production process of aquaculture photosynthetic bacteria and an aquaculture photosynthetic bacterium produced by the above-mentioned production process. Background technique [0002] Photosynthetic bacteria (PSB for short) are a group of bacteria that can use organic matter as oxygen donor and carbon source under anaerobic light or aerobic dark conditions to carry out photosynthesis without oxygen release. Prokaryotes capable of synthesizing the system are widely distributed in paddy fields, lakes, rivers, oceans, activated sludge and soil in nature, and are more common in waters with high concentrations of decaying organic matter. According to related classification, photosynthetic bacteria can be divided into 6 groups and 27 genera. Rhodospirillales that do not produce oxygen and photosynthesis are divided into purple bacteria, green bacteria, H...

Problems solved by technology

This method is easy to infect bacteria, such as figure 1 In the typical process of industrialized PSB production in the prior art, sodium hypochlorite needs to be added to the tap water, and it is left to stand overnight for disinfection, and then sodium thiosulfate needs to be added to the sterilized tap water to eliminate the chlorine gas in the tap water. to degrade

However, in the above-mentioned process, sodium hypochlorite is used to disinfect tap water, and there are problems of incomplete disinfection and residual hypochlorite radicals in tap water; tap water has high salinity, and the conductivity of about 900 μm / cm is unfavorable to the production of photosynthetic bacteria in the later stage; most production operations Carried out in the air, the contamination rate of miscellaneous bacteria is high; additional chemicals such as calcium hypochlorite and sodium thiosulfate are added to increase production costs; the disinfection time and photosynthetic bacteria culture time are long, which increases production time and labor time, which is not conducive to improving production efficiency

[0004] Therefore, develop a large-scale production optimization process of photosynthetic bacteria to solve the technical problems in the prior art such as incomplete disinfection of tap water, high salinity in tap water, long production time, high production cost, and residual chemicals that have an impact on the production of photosynthetic bacteria. Achieving high-efficiency, low-cost large-scale production of photosynthetic bacteria is an effective way to promote the healthy and sustainable development of the green aquaculture industry, and it is of great significance to promote the efficient development of my country's aquaculture industry
