Development of xylanase as detergent additive to improve laundry application

Abstract

Abstract The development of kitchen waste from UNISEL’s cafeteria as a substrate in the production of xylanase is an alternative way of converting waste to wealth. The production of xylanase as a detergent or detergent additive capable of removing plant stains compared to limited detergent applications that are unable to remove plant stains. Aspergillus niger was used in this study to degrade hemicellulose in kitchen waste and to secrete xylanase by solid state fermentation (SSF). Optimization of SSF parameters including substrate moisture content, inoculum size and incubation temperature were determined to optimize xylanase production. The finding of maximum activity of xylanase was identified at 80% of the moisture content, 8.0 mL of inoculum size and 30°C of the incubation temperature. The efficacy of xylanase (from optimized SSF parameters) as a plant stain remover is significantly effective compared to the commercial detergent used in this research. However, the mixture of detergent and xylanase can cause the chemical content of the detergent to interfere with the action of the enzyme and its efficacy in the removal of plant stains is less effective. It is also easier to use xylanase with water due to it is capable of producing excellent performance. This study demonstrated the high efficiency of the washing process using xylanase from kitchen waste and can be suggested for the laundry industry.
