The present application belongs to the technical field of plant active peptides, and particularly relates to an active peptide with anti-inflammatory and immune-regulating functions and application thereof. In order to provide a new bioactive peptide, polypeptides are prepared by protease hydrolysis of red kidney bean, and the enzyme-hydrolyzed polypeptides with a molecular weight less than 3 kDa are separated by ultrafiltration, and the polypeptide sequences are identified by LC-MS / MS. The active peptides FL and YF are screened by bioinformatics and molecular docking, and the amino acid sequences of the active peptides are FKSIGVKPPKGILL and YLFPESPARLPGF respectively. The active peptides can improve the survival rate, NO release amount, phagocytic capacity and cytokine production of RAW264.7 macrophages, can obviously inhibit the NO release amount of RAW264.7 cells induced by LPS, can inhibit the expression of inflammatory factors iNOS, TNF-alpha and IL-6, and can be applied to the preparation of anti-inflammatory or immune-regulating functional food or drugs.

The present application relates to a kind of red kidney bean bacteriostatic active polypeptide and its preparation method.The preparation method includes the following preparation steps: S100, raw material pretreatment: the red kidney bean dreg of extracting albumin is softened and grinded homogenization to be made into slurry by adding water;S200, hydrolysis: two kinds of neutral protease hydrolysis are added to the slurry, to obtain hydrolysate;S300, membrane separation: the hydrolysate is inactivated after enzyme, and solid-liquid separation is carried out, and the obtained filtrate is separated using the ultrafiltration membrane with the molecular weight cut-off 3000Da, and the obtained ultrafiltrate is desalted and concentrated using the nanofiltration membrane with the molecular weight cut-off 300Da, to obtain red kidney bean bacteriostatic active polypeptide concentrate.The polypeptide prepared by the method of the present application has inhibitory effect on streptococcus mutans, salmonella and staphylococcus aureus.Because these bacteria are common digestive tract pathogenic bacteria, the polypeptide can be used as a product for inhibiting harmful bacteria in digestive tract or as an external bacteriostatic product.

The invention belongs to the technical field of compound fertilizers, and particularly relates to a compound fertilizer for red kidney beans as well as a preparation method and application thereof. The compound fertilizer adopts a core fertilizer-coating structure, and the core of the compound fertilizer is that the core fertilizer comprises a composite microbial inoculum which is prepared by compounding rhizobium RH64 and lysinibacillus fusiformis according to the concentration ratio of 1: 2-2: 1, and synergistic urea, diammonium phosphate, potassium chloride, borax, sodium molybdate, fulvic acid and other nutritional and functional components. Field test results show that the compound fertilizer significantly improves nitrogenase activity of root nodules of red kidney beans, thereby effectively promoting growth of the red kidney beans, achieving great yield increase, and significantly increasing crude protein and total dietary fiber content in grains. The invention provides an efficient and reliable solution for solving the continuous cropping obstacle of the red kidney beans and improving the yield and quality of the red kidney beans.
