The present invention provides a detergent having a high detergency against corneum-derived stains, a method for evaluating the ability of an enzyme or a composition comprising the enzyme to degrade corneum-derived stains. A detergent comprising an M23A subfamily protease as an active ingredient. A method for evaluating the ability of an enzyme or a composition containing the enzyme to degrade corneum-derived stains, comprising obtaining the degrading activities of the test enzyme or the composition comprising the test enzyme on a reference peptide and one or more substrate peptides and evaluating the ability of the test enzyme or the composition comprising the test enzyme to degrade corneum-derived stains based on the degrading activities of the test enzyme or the composition comprising the test enzyme on the reference peptide and the substrate peptide, wherein the reference peptide is GGGGG or GGGG, the one or more substrate peptides are selected from the group consisting of GGGXG, GXGGG, GGXG, and GXGG, and X is any amino acid residue other than glycine.

Disclosed is a composition of a collagen peptide and an elastin peptide, method of producing the same and use thereof. The composition of the present disclosure consists of a collagen peptide and an elastin peptide; the collagen peptide is prepared by enzymatic hydrolysis of a collagen material with pepsin or trypsin, and the elastin peptide is prepared by enzymatic hydrolysis of an elastin material with papain and/or protease Protamex. In the present disclosure, an elastin peptide and a collagen peptide with molecular weight in a specific range are prepared by specific processes, and the composition composed of the two at a suitable ratio can simultaneously and significantly increase the amount of the elastin and collagen in a damaged skin in a small usage amount, and significantly increase the content of hyaluronic acid and hydroxyproline while decrease the content of MMP3, meanwhile, inhibit skin inflammatory factors.

Methods for the recovery of lipids, sugars, and proteins from microbial biomass by enzymatic digestion are disclosed. The methods involve treating microalgae with a fungal acid protease, or with a mixture of at least one protease and at least one amylase.

Provided is a process to produce a yeast-derived product as well as a yeast autolysate or yeast extract comprising at least 1% w/w reducing sugar based on the total dry matter weight of the yeast extract or yeast autolysate. Also provided is a process to produce a reaction flavour. The yeast extract or yeast autolysate is very suitable for the production of a reaction flavour.

Biodegradable polyester article comprising enzymes. The present invention relates to novel biodegradable plastic articles comprising a polyester and biological entities able to degrade such polyester, and wherein the biological entities are homogeneously dispersed in the plastic articles. The invention also relates to a process for producing such plastic articles, comprising a step of mixing biological entities with a selected carrier in a liquid composition or in a masterbatch with the polyester.

An apparatus for hydrolysing a product, comprising a continuous conduit having an inlet for receiving the product and an outlet for discharging the product, the conduit being formed so as to follow a path that winds around a longitudinal axis as the conduit extends parallel to the longitudinal axis between the inlet and the outlet, and a heating system for heating at least part of the conduit. The conduit is rotatable about the longitudinal axis so as to transport product received in the inlet towards the outlet.

Provided is a detergent having a high detergency against corneum-derived stains and a method for evaluating the ability of an enzyme to degrade corneum-derived stains. The detergent a M23A subfamily protease as an active ingredient. The method for evaluating the ability of the enzyme to degrade corneum-derived stains comprises obtaining the degrading activities of the test enzyme on a reference peptide and one or more substrate peptides and evaluating the ability of the test enzyme to degrade corneum-derived stains based on the degrading activities of the test enzyme on the reference peptide and the substrate peptide, wherein the reference peptide is GGGGG or GGGG, the one or more substrate peptides are selected from the group consisting of GGGXG, GXGGG, GGXG, and GXGG, and X is any amino acid residue other than glycine.

Methods, apparatuses, and systems are provided for processing a biological sample. Exemplary methods comprise transferring a swab associated with an aliquot of the biological sample into a sample transport media. The methods can provide efficient transfer of a target material such as cells or nucleic acid into the sample transport media for extraction, amplification, and detection of the target material.
