Biosoftening of arecanut fiber for value added products

摘要: Abstract The arecanut husk fibers are predominantly composed of cellulose and varying proportions hemicellulose, lignin, pectin protopectin. Microbes that selectively remove lignin without loss appreciable amounts fiber strength properties extremely attractive for the biosoftening fiber. fungal growth occurs during first 72 h incubation by one week, enzyme production reaches maximum level, thereby improving color softness Maximum MnP 233.2 IU ml−1 was observed at pH 7.0 Phanerochaete chrysosporium a activity 221.8 IU ml−1 5.0 strain. improvement (brightness) 321.3 IU ml−1 achieved in medium lacking both carbon nitrogen P. whereas 341.2 IU ml−1 only sp. treated with showed 35.1% 25.7% increase when compared to untreated Elongation 5.0% 4.2% control which had an elongation 3.7%. biosoftened can be exploited commercially furnishing fabrics, textiles etc blending cotton, viscose polyester.
