The invention discloses a staphylococcus saprophyticus NCSL-YWH2, and the preservation number of the staphylococcus saprophyticus NCSL-YWH2 is CGMCC (China General Microbiological Culture Collection Center) No.35847. The staphylococcus saprophyticus NCSL-YWH2 has the advantages that the staphylococcus saprophyticus The invention also discloses a culture method of the staphylococcus saprophyticus NCSL-YWH2 and an application of the staphylococcus saprophyticus NCSL-YWH2 in enriching a lithium element in a lithium-containing liquid. The staphylococcus saprophyticus NCSL-YWH2 disclosed by the invention is a staphylococcus microorganism which is reported for the first time and has the capability of enriching lithium ions from a lithium-containing liquid. The strain can be widely applied to lithium extraction of salt lake brine, unconventional lithium-containing water resources and various lithium-containing industrial wastewater, efficient enrichment and concentration of lithium ions can be realized by utilizing the strain, and a biological method has the characteristics of greenness and low carbon.

The invention provides staphylococcus saprophyticus as well as a culture system and application thereof in lipase production, and belongs to the technical field of microorganisms. The lipase producing strain PKS-3 is separated from oil-rich soil by using a plate method and belongs to staphylococcus saprophyticus, a grease degradation performance determination result shows that the lipase producing strain PKS-3 has a relatively good degradation effect on sunflower seed oil and other vegetable oil rich in linoleic acid, the degradation rate is 50% or above, and the lipase producing strain PKS-3 has the potential of degrading polyunsaturated fatty acid grease; the lipase in the strain is obtained through cloning, and a theoretical basis and an effective means can be provided for development and utilization of microbial resources and industrial application of the lipase.

The invention discloses a biological treatment and recycling method for synchronously removing carbon and enriching lithium from oil and gas field produced water, which comprises the following steps: 1) inoculating microorganisms into a liquid culture medium, and culturing to obtain a microorganism culture solution or culture; 2) directly adding and / or treating the microbial culture solution and / or culture obtained in the step 1) and then adding the microbial culture solution and / or culture into a reactor filled with oil and gas field produced water to be treated; (3) operating the reactor in the step (2), degrading organic matters in the oil and gas field produced water by microorganisms and enriching lithium ions; and 4) separating the microorganisms from the oil and gas field produced water, and extracting lithium ions enriched in the microorganisms. Wherein the microorganism is selected from one or a combination of more of the following microorganisms: staphylococcus saprophyticus, penicillium fistulosum, bacillus altitudinis, alternaria tenuissima and aspergillus sydowii. According to the method, recycling of lithium is achieved while oil and gas field produced water is recycled / discharged after reaching the standard, and the method has important significance on the national ecological environment and the new energy strategy.

The invention relates to the technical field of wine brewing, and particularly discloses a microbial liquid for improving the quality of Maotai-flavor liquor and application thereof.Through the synergistic effect of three microbial agents, a continuous metabolic complementary network is formed in a brewing system, and clostridium tyrobutyricum provides organic acid and part of precursor substances in the anaerobic stage; the issatchenkia orientalis dominates alcoholic fermentation and synthesis of main esters, and creates a chemical environment beneficial to metabolism of other strains; the staphylococcus saprophyticus enhances protein conversion and generation of special flavor substances. According to the method, the metabolic pathways of acids, esters, pyrazines and phenols in a brewing system are enhanced, so that key flavor substances of the Maotai-flavor liquor are systematically improved, the fragrance of the liquor body is stronger and more harmonious, the taste is more mellow and full, and the overall quality is remarkably improved.

This invention discloses a method for fermenting cigar tobacco leaves using a mixture of Staphylococcus saprophyticus and Ganoderma lucidum extract, and its application, belonging to the field of tobacco technology. The method includes the following steps: providing wrapper tobacco leaves; adding wet Staphylococcus saprophyticus cells and Ganoderma lucidum extract to the wrapper tobacco leaves and then fermenting them, turning the leaves during fermentation to obtain fermented tobacco leaves. This invention, by adding Staphylococcus saprophyticus and Ganoderma lucidum extract for synergistic fermentation during cigar wrapper fermentation, significantly increases chlorophyll and carotenoid degradation products in the middle stage of fermentation, and significantly accumulates phenylalanine conversion products and Maillard reaction products in the late stage of fermentation, thereby significantly promoting the production of aroma substances and enhancing the accumulation and harmony of aromatic substances. Furthermore, the fermentation method provided by this invention also effectively improves the color and appearance of the wrapper, providing a feasible path and theoretical support for optimizing the quality of cigar wrappers and developing high-end cigar products.

The invention belongs to the technical field of wastewater and sewage treatment, and relates to a preparation method and application of a multi-strain-ceramsite carrier compound for static denitrification purification of aquaculture sewage. The multi-strain-ceramsite carrier compound consists of rhodopseudomonas palustris, pediococcus pentosaceus, bacillus licheniformis, candida albicans, leuconostoc mesenteroides, cellulomonas flavigena and staphylococcus saprophyticus, and is prepared by loading the multi-strain-ceramsite carrier compound on a ceramsite carrier through a special process. When the compound is used for treating aquaculture sewage, strain layered feeding is realized through ceramsite carrier density difference, the aquaculture sewage can be efficiently treated, and odor generation can be remarkably inhibited. Application results show that the total nitrogen degradation rate, the ammonia nitrogen degradation rate and the COD degradation rate of the culture sewage treated by the method are 86.2%, 88.2% and 79.2% respectively. Through the synergistic effect of multiple strains, process innovation and precise spatial distribution control, efficient static purification of the breeding sewage is achieved, and an economical and feasible technical scheme is provided for rural pollution treatment.
