        Environmentally benign Scouring of Cotton Knits Using Locally Produced Acid Pectinase Enzyme

        Nabil A. Ibrahim,Basma M. Eid,Mohamed S. Abdel Aziz,Soha M. Hamdy,Safaa E. AbdAllah 한국섬유공학회 2019 Fibers and polymers Vol.20 No.4

        The main task of the present study is to pre-screen selected fungal strain (Fusarium oxysporum M1-EGY) isolatedfrom local agriculture soil and optimize cultivation conditions for an acid pectinase production. Experimental resultsdemonstrated the optimum conditions for achieving the highest enzyme activity (14.80 U/ml) were found to be: incubationperiod (8 days) at pH (5), temperature (30 oC), and shaking rate (150 rpm), apple pectin carbon source (2 %), and ammoniumphosphate as nitrogen source (0.2 gN/l). The positive impacts of utilizing the produced crude acid-pectinase in eco-friendlyscouring of various cotton knits as well as their subsequent bleaching and reactive dyeing have been confirmed. Additionally,the use of local resources for an acid pectinase production would encourage and promote local production of textile enzymesand their potential applications in Egyptian textile sector, taking in consideration efficiency, textile quality, environmental andeconomy concerns.
