中和剂对稀酸蒸爆玉米秸秆酶解效果的影响
Effects of neutralizing agents on enzymatic hydrolysis of corn stover pretreated by dilute acid-mediated steam explosion
摘要
Abstract
Com stovers pretreated by dilute sulphuric acid-mediated steam explosion were neutralized to pH 5 with Ca(OH) 2, NaOH and NH40H, or alternatively washed with water to the same pH. The cellulose conversion rates by enzymatic hydrolysis under the conditions of solide liquid ratio of 1: 10 and cellulases loading of 14 U/g cellulose were investigated. The results showed that after enzymatic hydrolysis for 72 h, the cellulose conversion rates of the cooresponding samples were up to 91.7％, 80. 7％, 83. 1％and 81.7％, respectively. Meanwhile, the effects of various factors on the efficency of cellulase hysrolysis were also discussed. Considering the cost and following fermentation process, the neutralizing agent NH4OH was the choice for the industrialization production.关键词
