Evaluation of the production’s
increase of keratinases enzymes
Keywords: Shaved, enzymes, tioglycolato, keratins, reducers.
ABSTRACT
The shaved-based conventional sodium sulphide and lime
gives the maximum values of pollution in the river area, contributing
50-60% to the total pollution in terms of biochemical oxygen
demand (BOD), chemical oxygen demand (COD ), total
dissolved solids (TDS).
From this study it can be concluded that the addition of reducing
agents to the culture medium, especially sodium thioglycolate,
increases the production of keratinolytic enzymes. In the
special case of T. ajelloi sodium thioglycolate was used not only
as a reducing agent but as a carbon source whereas in the case
of cysteine would also incorporating nitrogen source .
Thus, we can increase the production of keratinases for the
potential use at different stages of Leather Technology and the
ability to add value to solid waste, in this case the hair waste in
bioconversion processes related to fertilizers. |
