An environmental management technology for the processing of American aloe fibers using xylano-pectinolytic enzymes


The objective of this research was to find out the potential of bioscouring using xylano-pectinolytic enzymes, for degumming of aloe fibers. Bioscouring was optimized with 1 : 20 fiber to buffer ratio, using 10 IU xylanase and 3.2 IU pectinase in 50 mM buffer (pH 8.5), EDTA (3 mM), and Tween 80 (1%), at 50°C temperature with agitation rate of 50 rpm and treatment period of 60 min. Enzymatic treatment of aloe fibers increased brightness and whiteness by 55.67% and 24.88%, respectively and decreased yellowness by 44.11% as compared to alkaline fiber scouring, thereby replacing chemical scouring completely. Additionally, the pretreatment of aloe fibers with enzymes resulted in a 50% less consumption of bleaching chemicals with similar optical properties as obtained by 100% bleaching. This is the first report showing the eco-friendly bioscouring approach of aloe fibers, using enzymes produced concurrently from a bacterial isolate.
