Enhancement of Cotton Waxes Removal with Thermobifida Fusca Cutinase by Temperature Control Process
Melting point of cotton waxes and effects of temperature on cotton waxes removal were investigated. Based on these results a temperature control process for cutinase was developed to improve cotton waxes removal: Firstly cotton fabric was treated by cutinase at 70°C for 10 min, and then the treatment temperature was switched to 55°C and kept this temperature till to the end of the treatment. As a result, maximal cotton waxes removal of 67.69% for cutinase and 75.37% for combined enzymes (cutinase with pectinase and cellulase) were achieved, which was 17.96% and 13.88% higher than that of treatment at 55°C for cutinase and combined enzymes respectively. Moreover, the mechanism involved in enhancing cotton waxes removal in temperature control process was also discussed.
