Screening and Application of Alkalophilic Strains for Biological Scouring of Flax Rove
To achieve bio-scouring or biological degumming of the flax roving, an alkalophilic strain was screened from the rotten wrack around Zhoushan archipelago sea area. Determination of enzyme activity showed that the activities of petinase and xylanase were obtained, and enzyme activities are stable under 50°C and at pH values in the range of 6.5 to 9.0. It was utilized to scour the flax roving under alkaline conditions, and the result showed that the strain had a good characteristic of scouring, and less strength loss of flax fiber was 14.19%. Scanning electron microscopy (SEM) showed that the gum in the flax fiber was mostly degraded, and the most smooth fiber surface was displayed, compared with fiber untreated and scoured by caustic soda.
