摘要: 工厂化条件下对亚麻快速生物脱胶技术进行了规模化生产试验。结果表明,亚麻高效脱胶菌株Ym68'(E.herbicoli)的适宜培养条件为:35℃搅拌、pH6.5~7.5、通气量0.02 m3·m-3water·min-1、培养时间5~6 h。与传统温水沤麻方法相比,其脱胶时间缩短70%以上,长麻率提高31%左右,纤维强度提高25.9%;BOD5和SS排放总量分别减少33%和89%以上。

Abstract: A scale production trial of fast microbial retting of flax under industrial conditions was conducted. The results indicated that the best cultivating condition for rapid retting strain Ym68ˊ(E. herbicoli) was 35℃, stirring, pH 6.5-7.5, aerate 0.02m3·m-3water·min-1 and maintained for 5-6 h. Compared with traditional method, the retting time decreased by 70%, long fiber production increased by 31%, the fiber quality upgraded by 25.9%, the total effuluent discharge of BOD5 and SS reduced by 33% and 89%, respectively.
