Introduction

As an alternative to conventional chemical process for removal of hair from skins. The process employs solid state fermentation for the production of enzyme by a new Aspergillus flavus strain using wheat bran as substrate. The enzyme loosen hair from skins and eliminates bating step in leather processing. Enzyme has good caseinolytic activity over a broad pH range with no effect on the collagen or elastin.

Environmental Aspects: This process is environment friendly

Machinery / Equipments: Humidifiers; Air conditioners; Autoclaves; Kneader mixers; Pulverizer; Perforated trays; Hot air blowing system; Boiler etc.

Raw Materials: Wheat bran

Status Of Commercialization : Process standardised and tested in tanneries.

Techno Economics: Estimated investment for a plant of 300 TPA is around Rs. 10 millions

Technology Package: Process knowhow, process demonstration, quality assurance methods, project report, training of personal, assistance in implementation, data on effluents.
