Ramie offers excellent wearability compared to other fibrous material; however, since the inner structure of the fibers remains largely unexplored, this excellent wearability lacks a reasonable explanation. In this study, enzymatic peeling, using xylanase and laccase coupled with PM, FLSM, and SEM, was confirmed to be an effective and efficient method to characterize the inner structure of ramie fibers...
Morphological changes and biochemical process of ramie retting by RAMCD407 was investigated using microscopy techniques, including OM, PLM, FLSM and SEM coupled with enzyme activity analysis. Results showed that retting was completed within 56 h followed by 0.2% NaOH treatment. Residual gum content and breaking strength of the final fiber was 2.84% and 5.2 cN/dtex, respectively. This fulfills the...
A novel bioflocculant (MBF83) prepared using methanol wastewater as nutrient resource was systematically investigated in the study. The optimal conditions for bioflocculant production were determined to be an inoculum size of 8.6%, initial pH of 7.5, and a methanol concentration of 100.8mgL−1. An MBF83 of 4.61gL−1 was achieved as the maximum yield. MBF83 primarily comprised polysaccharide (74.1%)...
A novel strain (designated as SW-2) which could convert chromotropic acid into bioflocculants was isolated from chromotropic acid wastewater. Conditions for bioflocculants production were optimized by response surface methodology (RSM) and determined to be inoculum size 7.74%, initial pH 6.9, and CODCr of the chromotropic acid wastewater 425mg/L. The yielded bioflocculant was primarily consisting...
