摘要: 对假单胞菌DA10(CGMCC No.3851)在亚麻粗纱煮练中的应用进行了研究。通过试验研究了发酵液用量、初始pH值、煮练温度和处理时间对细菌煮练的影响。试验表明:当发酵液用量150mL,初始pH值9,煮练温度40℃,时间7.5h左右时,细菌煮练可以获得较好的效果。但细菌煮练的作用较柔和,在细菌煮练前引入预处理可以明显改善细菌煮练效果,提高纤维分裂程度和纤维强度,其中以低浓度碱煮-细菌联合煮练的效果为最优。同时,也使用扫描电镜对胶质的去除情况进行分析,结果表明:经细菌煮练后的纤维虽获得了分裂但纤维上仍有胶质,而碱煮-细菌联合煮练后纤维上的胶质去除较彻底。

Abstract: An investigation of scouring of flax roves with pseudomonas sp DA10(CGMCC No.3851) and their polysaccharide-degrading enzymes was carried out. Dosage of fermentation beers, initial pH, scouring temperature and treatment time were studied. The result indicated that flax roves treated with 150mL fermentation beers at 40℃ and pH 9 for more 7h or less also could gain satisfied performances in mild bacteria scouring. However, pretreatments intervention can improve bacteria scouring greatly with higher degree of splitting and fiber bundles strength. The properties of fibers after low-concentration alkali-bacteria combined scouring were the best. SEM was also used to assess removal of gummy materials. It indicated that flax roves treated by bacteria scouring at initial pH 9 and 40℃ for 8h could achieve a specific degree of separation in spite of incomplete removal of gummy materials. When alkali pretreated fibers were subsequently treated by bacteria scouring, a complete removal of gummy materials was observed.
