| Abstract: | The present study is aimed at finding out the protease enzyme specific for hydrolysis of polyamide fabric surface and its
production in cost effective medium for application in textile industry.
Hydrolysis of polyamide fabric by protease enzymes produced by Bacillus
isolates 2W, 16P and 36P is confirmed by improved hydrophilic properties,
enhanced staining with basic dyes, scanning electron microscope and FTIR. SEM
images of protease treated fabric show heterogeneous appearance as cracks, pits
and rough surfaces. FTIR measurements prove the increase in free amino groups
on the surface of protease treated polyamide. At the same time, treated fabric
shows good physical and mechanical properties. It is also observed that the
loss of strength of treated fabric is 6%. Air permeability increases and static
charges reduce. Bacillus isolate 16P is chosen for economic production
of polyamide surface modifying protease enzyme using
14 agro-industrial by-products as growth media. The highest protease production
(175 U/mL) is achieved in media containing 6% linen meal at pH 7, after
72 h incubation period. Addition of KCl to linen meal medium enhances the protease
production to about 18%.
