亚麻粗纱碱性脱胶菌株的筛选鉴定及脱胶效果
Screening and identification of alkalophilic degumming strains of flax roving and evaluation of its effects
摘要
Abstract
Alkalophilic degumming strains DA8 was screened from the rotten wrack around Zhoushan ar-chipelago sea area. It was characterized as Cellulomonas sp by testing the strain morphology, physiology, bio-chemistry and the 16S rDNA sequences. Determination of enzyme activity showed that the activities of petin-ase and xylanase were obtained, and enzyme activities were stable under 50 ℃ and at pH 6.5~9.0. It was uti-lized to degum the flax roving under alkaline condition, and the result showed that the strain had a good result of degumming, and less strength with 14.19% of loss. Scanning electron microscopy (SEM) showed that com-pared with the untreated fiber and degummed by NaOH, the gum on the surface of flax fiber was mostly re-moved, and the surface of the flax fiber was smooth.关键词
