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.

Key words: Flax, Microbial retting, Industrial production
