\u78b1\u9897\u7c92\u7403\u78e8\u9884\u5904\u7406<\/strong>: Efficient saccharification of wheat straw pretreated by solid particle-assisted ball milling with waste washing liquor recycling<\/strong><\/p>\n

Recently, PhD student Miss Xiao-le Liu supervised by Prof. Zhen Fang<\/strong> published a research article in Bioresource Technology about ball milling pretreatment with NaOH solid particles for enzymatic hydrolysis of wheat straw.<\/p>\n

Wheat straw was pretreated using ball milling (BM) promoted by solid particles (NaOH, NaCl, citric acid). NaOH showed the best synergistic interaction effect, due to the breakage of \u03b2-1,4-glycosidic bonds among cellulose molecules by the alkali solid particles induced by BM. NaOH-BM pretreatment decreased the straw crystallinity from 46% to 21.4% and its average particle size from 398.3 to 50.6 \u03bcm in 1 h. After 4 h milling, the reducing-end concentration of cellulose increased by 3.8 times from 12.5 to 60.2 \u03bcM, with glucose yield increased by 2.1 times from 26.6% to 82.4% for 72 h enzymatic hydrolysis at cellulase loading of 15 FPU\/g dry substrate. The pretreatment washing liquor was recycled for the re-treatment of partially pretreated biomass at 121 \u00b0C for 30 min, resulting in 99.4% glucose yield by enzymatic hydrolysis. BM assisted with alkali particles was an effective approach for improving biomass enzymatic saccharification.<\/p>\n
