Strain Engineering for Keratinase

Online Inquiry

CD Biosynsis has established a superior synthetic biology platform to help our customers create scalable and efficient ways to produce keratinase. We are committed to developing effective synthetic biology strategies to overcome all the difficulties associated with traditional keratinase production and applications.

Advantages of Synthetic Biology-Driven Keratinase Production

Keratin is a stubborn fibrous protein found in large quantities in keratinous wastes such as feathers and hair. Keratinases are a class of proteases that can degrade keratin into amino acids. Different types of keratinases have different biochemical properties. They have various potential applications in multiple fields such as biomedicine, detergent, leather and textile industries, animal feeding, and biofertilizer production. So far, the traditional large-scale keratinase production process has faced great challenges in terms of enzyme yield, and it is urgent to find a method to improve the yield of keratinase. In addition, the biological yield of keratinase from natural keratinolytic hosts is low, and all of these problems greatly hinder the large-scale use of this enzyme. Emerging engineering strategies and advanced technological tools in synthetic biology allow the redesign and optimization of new biological pathways to construct engineered microbial strains for the efficient production of keratinase, which can boost the yield of keratinase.
