The application discloses a method for high-efficiency degradation of high-salinity wastewater by salt-tolerant bacteria in a composite inorganic salt system, and relates to the technical field of biological treatment of high-salinity industrial wastewater.The method realizes directional strengthening of the salt-tolerant performance of three strains of Staphylococcus xylosus, Alcaligenes faecalis and Bacillus cereus by a gradient-increasing NaCl domestication method.Under the condition of 40-50 g / L high salinity, the growth amount of the domesticated strains is increased by 30-40% compared with that of the non-domesticated strains, effectively relieving the osmotic pressure stress and metabolic enzyme activity inhibition of the microorganisms in the high-salinity environment.Meanwhile, the composite salt-tolerant bacteria agent is compounded based on functional complementation, and the agent has the abilities of efficient denitrification, phosphorus removal and organic matter degradation, and can adapt to the composite inorganic salt system of NaCl, CaCl2 and MgSO4 alone or in combination, and can realize synchronous and efficient removal of COD, ammonia nitrogen, total nitrogen and total phosphorus in a wide salinity range of 10-80 g / L.The method breaks through the technical limitation that the existing salt-tolerant bacteria only adapt to a single salt system and have single degradation function, and greatly widens the applicable scenarios of the biological method in the treatment of high-salinity wastewater.

This invention belongs to the field of bio-fermentation technology, and particularly relates to fermenting bacteria, a fermentation compound agent prepared based on these fermenting bacteria, and specific preparation methods and applications of the fermentation compound agent. The fermenting bacteria are selected from *Bacillus licheniformis* CY-1 and *Alcaligenes faecalis* CY-2; the *Bacillus licheniformis* CY-1 is deposited at CGMCC with accession number CGMCC No. 21241; the *Alcaligenes faecalis* CY-2 is deposited at CGMCC with accession number CGMCC No. 21242. This invention achieves effective composting of easily perishable waste through the specific combination of *Bacillus licheniformis* CY-1 and *Alcaligenes faecalis* CY-2. During the composting process, it effectively fixes nitrogen and reduces emissions, improving the quality, economic value, and utility of the treated easily perishable waste compost product.

This invention belongs to the field of microbial technology, specifically relating to a strain of direct ammonia-oxidizing fecal alkalogen AP3-14 and its applications. The fecal alkalogen provided by this invention (… Alcaligenes faecalis AP3-14 was deposited on November 17, 2025, at the China General Microbiological Culture Collection Center (CGMCC), with accession number CGMCC No. 36650, located at No. 3, Courtyard 1, Beichen West Road, Chaoyang District, Beijing. This strain not only possesses direct ammonia oxidation capabilities, achieving efficient denitrification under aerobic conditions through this pathway, but also simultaneously degrades ammonia nitrogen and phenol in wastewater or sewage. Furthermore, this strain can tolerate a wide range of ammonia nitrogen concentrations, phenol concentrations, and pH levels.

This invention relates to the field of biodegradation technology, and discloses a fecal alkaloid bacterium, YZ-1, and its application in the degradation of succinate. The fecal alkaloid bacterium (Alcaligenes faecalis) YZ-1 is deposited at the China Center for Type Culture Collection (CCC), accession number M 2026471, deposited on March 19, 2026, at Wuhan University, Wuhan, China, 430072, China. Experimental verification shows that this fecal alkaloid bacterium YZ-1 has good succinate degradation efficiency, achieving efficient degradation of succinate at initial concentrations up to 2.5 g / L. Furthermore, it exhibits a wide adaptable pH range and strong tolerance to the substrate succinate. Therefore, the fecal alkaloid bacterium YZ-1 shows promising application prospects in the industrial degradation of succinate.
