    Abstract:

Applications: Lime and sodium sulfide is completely eliminated during dehairing and fiber opening process for raw materials by adding water and proteolytic enzyme. It exhibits activity at experimental pH and experimental temperature, optionally in the presence of silicate salt to produce soft and subtle leather.
Advantages: Replacing the conventional hair burning and osmotic swelling methods through use of protease and amylase for selective unhairing and fibre opening, Enzyme only dehairing and fibre opening without the use of lime and sulphide. Provides elimination of one unit operation used in conventional leather making (deliming) thereby enhancing the productivity, and Enables reduction in process time and usage of chemicals.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
