Enzymatic Degumming of Banana Fibers by Enterobacter cloacae PMC04 for Fineness Improvisation: An Eco-friendly Approach

Abstract

ABSTRACT Banana fibers could gruntle the thirst for natural fibers in textile industries. Banana fibers are prominent for eco-friendliness, durability, and biodegradability. Our study demonstrates that Enterobacter cloacae PMC04, isolated from banana waste decomposed soil, could produce pectinolytic enzymes using dried banana pseudostem as solid substrate by fermentation and their application in banana fiber degumming for textile processing. Enterobacter cloacae PMC04 exhibited elevated pectinase activity (177.1901 U/ml) and pectin lyase activity (34.21818 U/ml) with citrus pectin and yeast extract under optimal pH (pH 10.0) and temperature (45°C) conditions. In reconciliation with the obtained results, it is found that pectinase enzyme is suitable for the degumming of banana fibers. The optimized degumming condition of banana fiber was identified to be 55°C, 4 hours and 30% enzymatic dosage. The maximum galacturonide released from the fiber degumming system was recognized to be 0.8121 mmol/ml. The surface morphology, functional group, thermal analysis, and tensile analysis of the enzymatic degummed banana fiber were significant compared to the chemically treated fiber. Based on the studies, it is inferred that enzymatic degumming of banana fiber could be regarded as an alternative approach for feasible application in textile industries
