Leather processing involves many sequential steps form raw hide to the processed leather. All these steps define the quality of leather in order to perform in the prescribed conditions. Dehairing of raw hide is one of the most important steps which define removal of hair, fat and other unnecessary things form raw hide. The most convenient way to achieve perfect dehairing is use of enzyme and specifically protease which dissolve the hair protein without affecting structure of skin. In this process generally alkaline and neutral proteases have been used extensively since last two decades. Though the conventional protease are efficient for dehairing of raw hide but the stability of these protease in various temperatures and chemical environments hamper their activity. In many instances the process will run for long duration which again reduces the activity of enzymes. Thermostable proteases form microbial sources are the better option to render the problem of stability of conventional protease in the different temperatures and chemical environments. Many of bacterial strains naturally adapted their habitat in higher temperature and the enzymes of such bacterial strains are very stable. Many of thermostable proteases have been isolated, purified and implemented in various industrial processes which have been limited due to stability complication of conventional protease. Here in this article we have summarized the potential role of thermostable proteases in leather industry and more specifically in dehairing of raw hide.
