This invention discloses a method for screening the stability of biomass-derived hard carbon raw materials. The method involves treating biomass materials from different sources and batches that can be used to prepare hard carbon with an acid solution, then testing the sugar content, ash content, and coin capacity of the finished hard carbon. The method utilizes the relationship between these parameters to simply and quickly screen out biomass-derived hard carbon raw materials with good stability, thereby obtaining biomass-derived hard carbon materials with excellent battery cycle stability and good electrochemical performance. When the biomass ash content, sugar content, and coin capacity of the biomass-derived hard carbon after acid treatment satisfy the relationship 10≤α / β×σ≤50, an effective balance between biomass ash and sugar content can be achieved. This balance allows for the formation of a specific porous structure, increasing sodium storage sites and improving sodium ion conductivity, while also preventing excessive ash and impurities from affecting the electrochemical performance of the hard carbon material. This ensures the high energy storage capacity and excellent cycle stability of the hard carbon material.

The invention belongs to the field of microbial technology, and specifically relates to a strain of acid fish lactobacillus PKC6 and an application thereof. The acid fish lactobacillus PKC6 is deposited in the General Microbiological Center of the China Microbiological Culture Collection Administration Committee, and the deposit number is CGMCC NO. 27201. The new strain of acid fish lactobacillus PKC6 screened by the invention is resistant to gentamicin, polymyxin B, vancomycin, kanamycin and norfloxacin, sensitive to ampicillin, penicillin, cephalexin and doxycycline, and has a good inhibitory effect on Escherichia coli and Staphylococcus aureus; the strain screened by the invention, after being compounded with a composite enzyme and co-fermented with palm meal, can greatly increase the content of nutrients in the fermentation product, and has a more obvious promoting effect on the intestinal development of raised animals, thereby achieving the purpose of improving the palatability of feed and promoting intestinal development.

The present invention belongs to the field of microorganisms, and specifically relates to a strain of Pediococcus pentosaceus PKC10 and its application. The Pediococcus pentosaceus PKC10 is deposited in the General Microbiological Center of the China Microbiological Culture Collection Administration Committee, and the deposit number is CGMCC NO.27203. The new strain Pediococcus pentosaceus PKC10 screened by the present invention is resistant to gentamicin, polymyxin B, vancomycin, kanamycin and norfloxacin, sensitive to ampicillin, penicillin, cephalexin and doxycycline, and has a good inhibitory effect on Escherichia coli and Staphylococcus aureus; the screening method provided by the present invention is simple and efficient; the screened strain has good application prospects in preparing fermentation agents, further preparing feeds, etc., turning agricultural and sideline products into treasures, broadening the source of feeds, reducing breeding costs, alleviating the contradiction of insufficient feed supply, and being conducive to the development of animal husbandry.
