摘要： Using site-directed mutagenesis to mutate the Xanthomonas campestris pectate lyase gene, variants of Xanthomonas campestris pectate lyase with improved thermostability and/or enzymatic activity have been expressed in Escherichia coli, and then isolated and purified. The mutant Xanthomonas campestris pectate lyases are more effective than the wild-type enzyme, also expressed in E. coli, in removing pectic compounds from natural hemp fiber.

摘要： A production technology for natural bamboo fibers is applied in producing woven bamboo fibers, non-woven bamboo fibers, and reinforcing composite bamboo fibers. The woven bamboo fibers are produced by steps of cutting to a certain length, slicing, flattening, softening, dividing, debonding, rinsing, soaking in oil, drying, and opening. The non-woven bamboo fibers and the reinforcing composite bamboo fibers are produced by steps of cutting to a certain length, slicing, flattening, softening, dividing, debonding (optional), rinsing, and drying.

摘要： A method of producing a fine fiber, including treating a cellulose raw material with an enzyme; and fibrillating the treated cellulose raw material; treating with the enzyme under a condition where at least a ratio of endo-glucanase activity to cellobiohydrolase activity that is 0.06 or greater. The cellulose raw material may be a plant fiber. The method efficiently produces a fine fiber from a cellulose raw material at low cost and with a low environmental burden, a fine fiber, and a non-woven fabric.

摘要： A solvent spun bamboo fiber with a high wet modulus and a producing method thereof are disclosed. The producing method includes: activating by adding a bamboo pulp into de-ionized water, adjusting the pH value, adding cellulase and adjusting the pH value by adding alkali; squeezing by vacuum dehydration; pre-dissolving by adding an aqueous solution containing 50-88% by mass of N-methylmorpholine-N-oxide; then dissolving by putting the above pre-dissolved mixture into a dissolver, heating, vacuumizing, dehydrating, dissolving, homogenizing and defoaming; spinning by spraying through a spinneret and forming a bamboo fiber by dry-wet spinning; water washing; bleaching; oiling; and drying. The present method is simple to operate, free of industrial pollution, low energy consuming, and highly safe. The bamboo fiber produced by the present method not only keeps the natural physical and chemical properties of bamboo fiber, but also has a high wet modulus without harmful chemical residues.

摘要： Embodiments of the present disclosure generally relate to materials and methods for producing a wide range of raw materials from plant biomass. In certain embodiments, the present disclosure provides materials and methods for efficient decortication of plant biomass using a thermally regulated process to generate reactive oxygen species in the presence of a catalyst. Embodiments of the present disclosure address the need for improved methods with which to obtain a wide range of raw materials from plant biomass without the need for industrial decortication machines and without producing harmful industrial waste.
