Applications

Keratinase hydrolyzes keratin-rich materials into soluble peptides and amino-acid rich hydrolysates. It is widely used to convert feather, hair, and wool waste into feed-grade proteins, biofertilizers, and value-added cosmetic ingredients.

🪶

Feather Meal Processing

Hydrolyzes keratin in poultry feathers to convert waste into digestible, high-protein feather meal for animal feed.

💇

Hair & Wool Waste Valorization

Degrades keratin-rich waste from barbershops, wool processing, and slaughterhouses into usable protein hydrolysate.

🌱

Biofertilizer Production

Transforms keratin waste into nitrogen-rich liquid biofertilizer, providing a slow-release amino acid source for crops.

🧴

Cosmetic Keratin Peptides

Produces keratin peptides from feather/wool waste for hair repair, nail strengthening, and skin care formulations.

🐔

Prion Decontamination Research

Studied for degradation of prion proteins, supporting potential research directions for BSE/CJD decontamination of surgical instruments.

♻️

Circular Economy Use-Cases

Enables waste-to-value conversion of keratin (3rd most abundant biopolymer), supporting zero-waste processing goals.

Frequently Asked Questions

What is Keratinase (EC 3.4.99.11) used for?

It is used to hydrolyze keratin-rich materials such as 🪶 poultry feathers, 💇 hair and wool waste, and related keratin by-products into soluble peptides/protein hydrolysates for feed, biofertilizer, and cosmetic ingredient applications.

What pH and temperature should I run for Keratinase?

For best performance, operate within pH 7.0–10.0 and 50°C–70°C. Final dosing and exact conditions should be confirmed through your substrate-specific trials.

How should I interpret the activity value (10,000–100,000 U/g)?

The range reflects measured enzyme units per gram using the keratin azure assay. Higher activity typically enables faster keratin breakdown at the same dosage; formulation should be optimized for your process.

What substrate types can Keratinase handle?

Keratinase is designed for tough keratin substrates including poultry feathers, hair, and wool-derived materials. It is commonly applied to waste streams from feed, textile, and slaughterhouse operations.

How should I store Keratinase to maintain shelf life?

Store sealed in a cool, dry place. The shelf life is 12 months under proper storage conditions; avoid moisture exposure and follow the COA/TDS guidance provided with your shipment.
