The production of TRB microbial preparations and beneficial microorganisms for water purification using high-yield strains (including genetically engineered microorganisms) employs a simple and easy-to-operate bioengineering fermentation method. The fermentation raw materials are readily available, the fermentation cycle is short, the yield is high, and the post-production processing is simple. All the strains used in this project, including the production strain, microbial preparations, and beneficial microorganisms, are international innovations or advanced varieties. In terms of process design, current internationally accepted processes and equipment are utilized, such as deep liquid axial flow fermenters and pressure filtration sterilization systems, to produce products that are liquids and can be directly used. There is no issue of secondary pollution during the production process.
