摘要： The present disclosure discloses Saccharopolyspora and application thereof in reducing biogenic amines, belonging to the technical field of food fermentation. Saccharopolyspora jiangxiensis J3 is screened from wheat koji and has been preserved in China Center for Type Culture Collection (CCTCC) on Apr. 30, 2020, with a preservation number of CCTCC NO: M 2020104. According to the present disclosure, the strain is applied to a food fermentation system, and results show that the strain does not affect normal fermentation of food, and has an effect of reducing the content of biogenic amines in fermented alcoholic drinks, fermented food and fermented condiments, so that the strain has broad application prospects in the field of food brewing.

摘要： A method for promoting the rapid precipitation of travertine crystals by algae is disclosed. Microalgae is added to a body of water having a calcium ion concentration of 100-500 mg/L and stirred. The amount of microalgae is 0.1-8×108 cells/L. The invention adopts a method for promoting the rapid precipitation of travertine crystals by algae, which significantly improves the sedimentation rate of travertine crystals. At the same time, there are pseudomonas in the calcified water body of algae, which can be used for algae-lysing bacteria isolation and purification.
