【摘要】：随着灵芝产业的不断壮大,每年因种植灵芝而产生大量废段木。该文在对废段木组成成分分析的基础上,研究了酸性电解水爆破处理废段木酶解工艺。废段木经酸性电解水预煮后高温瞬时爆破处理来破坏组织结构及纤维素结晶状态,以半纤维素去除率和纤维素损失率为考察指标,通过单因素试验及正交试验确定了反应的最优爆破条件为酸性电解水p H 1.8、爆破温度180℃、爆破时间60 s、预煮液固比为20:1(m L:g)。此最佳条件下半纤维素的去除率为94.20%,纤维素的溶出率为12.57%;经酸性电解水爆破处理后酶解率达86.40%,爆破残渣酶解效果表明利用强酸性电解水爆破处理灵芝废段木能够有效破坏纤维素结晶状态,利于纤维素酶酶解。
[Abstract]:With the growing of Ganoderma lucidum industry, a large number of waste wood are produced every year because of growing Ganoderma lucidum. Based on the analysis of the components of waste wood, the enzymatic hydrolysis process of waste wood by acid electrolytic water blasting was studied in this paper. The structure and crystalline state of cellulose were destroyed by the instantaneous blasting treatment of waste wood after pre-boiling with acidic electrolytic water. The removal rate of hemicellulose and the loss rate of cellulose were taken as the index of investigation. Through single factor test and orthogonal test, the optimum blasting conditions were determined as follows: acidic electrolytic water pH 1.8, blasting temperature 180 鈩，
