There is provided amino acid cleaving reagents with improved cleavage activity, allowing for more structural information to be obtained from polypeptides in sequencing reactions.

The present invention relates to a method for solubilisation or hydrolysis of Municipal Solid Waste (MSW) with an enzyme blend and an enzyme composition for solubilization of Municipal Solid Waste (MSW), the enzyme composition comprising a cellulolytic background composition and a protease, lipase and/or beta-glucanase.

The present invention discloses a complexing agent for promoting decomposition of loquat leaf litter, which belongs to the technical field of plant science. According to the present invention, the mixed solution of Pseudomonas solution, lignin peroxidase, and leucine aminopeptidase solution is applied to the loquat leaf litter, and after in-situ decomposition for four months, the mass loss rate and the decomposition constant of the loquat leaf litter are significantly increased, thereby effectively promoting the decomposition of the loquat leaf litter. The present invention first proposes that the decomposition of the loquat leaf litter is influenced by externally applying a combination agent of enzyme and bacterial solution, which is simple in operation, and promotes the decomposition of the loquat leaf litter while increasing the speed of returning organic matters to soil, thereby improving soil fertility.

The present invention relates to a hydrolyzed collagen formulation for use in decreasing blood glucose. The hydrolyzed collagen is obtained by enzymatic hydrolysis of a collagen-containing material with a combination of enzymes comprising two or more enzymes selected from the group consisting of a neutral protease, a carboxypeptidase, and an aminopeptidase. The hydrolyzed collagen formulation is particularly suitable as a food supplement, such as for use in ameliorating hyperglycemia and/or a risk factor hyperglycemia.
