Keratinase

inquiry

Cat No.

KGZ-001

Description

Keratinase is a proteolytic enzyme preparation that degrades keratin, a fibrous structural protein rich in disulfide bonds found in feathers, wool, hair, horns, and nails. It hydrolyzes keratinous materials into peptides and amino acids under mild conditions.

Abbr

Keratinase

Alias

Keratinolytic protease; Keratin hydrolase

Source

Produced by microbial submerged fermentation (typical industrial preparation)

Applications

Feed processing: degradation of feather meal and keratinous by-products to improve protein digestibility.
Leather and textile processing: modification of keratin-containing materials.
Detergent formulations: removal of keratin-based soils.
Waste treatment: biodegradation of keratin-containing waste such as feathers and hair.

Appearance

Light yellow to brown powder

Package

25 kg/bag or drum (customizable)

Product Overview

This keratinase preparation is an industrial enzyme product designed for efficient hydrolysis of keratin substrates, supporting improved utilization of keratinous protein resources.

Form

Powder

Enzyme Commission Number

EC 3.4.21.- (serine-type endopeptidase, keratinolytic)

Specificity

Hydrolyzes peptide bonds within keratin and other keratinous protein substrates; active against the compact disulfide-crosslinked keratin structure.

Optimum pH

Typically near neutral to slightly alkaline (confirm with batch COA)

Optimum temperature

Typically 40-60 °C (confirm with batch COA)

Storage

Store in a cool, dry place below 25 °C in the original sealed packaging, protected from direct sunlight. Shelf life: 12 months under recommended conditions.

Warnings

Enzyme preparations are proteinaceous substances. Inhalation of enzyme dust or aerosols may cause allergic reactions in sensitive individuals. Wear a dust mask, gloves, and eye protection during handling; rinse immediately with plenty of water if contact occurs.

Function

Catalyzes the hydrolysis of keratin into soluble peptides and amino acids, facilitating the conversion of keratinous waste into utilizable protein resources.

Synonyms

Keratinase; Keratinolytic protease; Keratin hydrolase

Substrates

Keratin (feathers, wool, hair, horn); general protein substrates

Grade

Industrial / feed grade (confirm grade with supplier)

Usage

Recommended dosage varies by substrate and process; typically applied at 0.05-0.5% by weight of keratinous material with process optimization by trial.
