Abstract: The present disclosure relates to the technical field of agricultural microorganisms and crop cultivation and more specifically relates to a compound mycorrhizal fungus growth promoting agent and an agricultural-photovoltaic complementary planting method for Dioscorea composita. The compound mycorrhizal fungus growth promoting agent for Dioscorea composita includes Glomus mosseae, Streptomyces chartreusis and plant growth promoting rhizobacteria, and can greatly improve photosynthesis of Dioscorea composita under a photovoltaic panel and promote growth and development of Dioscorea composita. The compound mycorrhizal fungus growth promoting agent is used, an unoccupied land under a solar photovoltaic panel is utilized, and a high-ridge close planting method is used to combine a solar photovoltaic industry and Dioscorea composita planting. The whole planting process is easy to operate, the cost is low, and three-dimensional value-added utilization of land is achieved.

Abstract: Disclosed is a method for producing biogas from a waste liquid/residue after diosgenin extraction by aluminum chloride. Specifically, in a fermentation vessel, an anaerobic sludge and a waste residue from diosgenin extraction by aluminum chloride are added at a volatile solids ratio of (1-3):(1-2), or a seeding sludge and a diosgenin waste liquid are added with an organic loading having a VS:COD ratio of (1-2):(1-2); and then the above components are fermented at 35-37° C. for 5-25 d such that biogas is produced. According to the method of the present invention, the maximum cumulative biogas production rates are 255.4 mL/g VS for waste residue and 326.9 mL/g COD for waste liquid, and throughout the fermentation period, ammoniacal nitrogen values are below 1500 mg/L and pH variation is within the normal range, and the COD removal rate for the fermentation broth is 91.11%.

Abstract: An objective of the present invention is to provide a liver disease regulatory formulation, which is beneficial to prevent the occurrence and development of a chronic liver disease by remodeling a liver regeneration microenvironment. The liver disease regulatory formulation, comprises a hepatocyte-derived liver progenitor cell or a secretory supernatant of the hepatocyte-derived liver progenitor cell.

Abstract: An amplifying method of pancreatic cells is provided. The amplifying method includes performing digestion, resuspension, discontinuous density gradient centrifugation treatment and amplifying treatment sequentially. The mammalian pancreatic duct is used as the source of pancreatic precursor-like cells in the amplifying method, and islet cells and acinar cells in the cell clusters obtained by the discontinuous density gradient centrifugation treatment are removed. It is beneficial to improve the yield of the pancreatic precursor-like cells availably, and avoid the ethical restrictions and possible carcinogenic risks caused by using the embryonic stem cells. The amplifying medium used comprises a reprogramming substance composed of several small molecule compounds. It can avoid the risks of non-specific and off-target deletion that are easily caused by the use of the gene-editing methods to change the gene sequence.
