The embodiment of the invention discloses aspergillus niger NO1 and application thereof. The Aspergillus niger NO1 disclosed by the invention is preserved in the Guangdong Microbial Culture Collection Center on November 21, 2025, the preservation address is the 5th floor, No.59 building, No.100 Courtyard, Xianlie Middle Road, Guangzhou, and the preservation number is GDMCC No: 67338. According to the invention, the bottom mud and high-enrichment culture sewage of sea farms in Zhangzhou Dragon Sea as well as Zhangzhou Dragon Sea are used as samples, and are subjected to primary screening and secondary screening culture to obtain a strain with excellent growth performance and good utilization performance on sodium nitrite. Through identification, the strain is aspergillus niger NO1, has an efficient aerobic denitrification function, shows excellent degradation efficiency on nitrite in aquaculture water, is good in safety, does not generate adverse effects on aquaculture organisms and water environment, and has a wide practical application prospect in the field of aquaculture water quality purification.

This invention provides a method for synergistically preparing a composite carbon source using byproducts of wet thermal oxidation of food waste and biodiesel byproducts. The method includes the following steps: After sorting, slurry preparation, and three-phase centrifugation for oil separation, the organic slurry undergoes wet thermal oxidation treatment, followed by dehydration to obtain a liquid phase (oxidation liquid). This liquid phase is then compounded with biodiesel byproducts such as glycerol and glucose to prepare a composite carbon source with high bioavailability and non-toxicity. The composite carbon source prepared by this invention can be widely applied in municipal, agricultural, livestock, food waste, and industrial wastewater biochemical treatment processes to meet carbon source requirements.

The application belongs to the technical field of utilization of waste biomass by microorganisms, and specifically discloses an abnormal williamsonia strain Y8 and application thereof in beer dreg fermentation. The preservation number of the strain is CCTCC NO: M 2026579. The strain has good tolerance to extreme chemical environments such as high salt, high sugar, strong acid and high-concentration ethanol; can ferment polysaccharides and monosaccharides; under the condition of rich nutrition, the content of cell protein can reach 57%; can adapt to the liquid physicochemical environment of beer dregs and effectively utilize beer dregs to grow. With the aid of enzyme preparation composed of beta-glucanase and xylanase, the efficiency of the strain in utilizing beer dregs to grow is significantly improved, and after 72 h of fermentation, the fermentation liquor with viable cell count of the strain ≥1.8×10 9 CFU / mL is obtained, and the prepared fermentation feed is effectively enriched with total phenols and improved in antioxidant performance. The application is green, mild and efficient, and has excellent application prospect.
