大豆渣制备细菌纤维素的研究
Preparation of Bacterial Cellulose with Soybean Residues
摘要
Abstract
Bacterial cellulose (BC) is nano cellulose produced by microorganisms. Its high production cost, especially the cost of carbon source needs to be decreased for its industrialization and commercial application. Through use of cheap and rich soybean residues as raw materials, which are waste after extraction of oil and protein, fermentable sugars were obtained by enzymatic hydrolysis of the cellulose residues after dilute acid pretreatment of the soybean residues. The acid pretreatment liquid and enzymatic hydrolysate was tried to be used as carbon source for production of bacterial cellulose, respectively. The results showed that the yield of BC with enzymatic hydrolysate as the carbon source was significantly higher than that from acid pretreatment liquid. BC production with Ca(OH)2-treated enzymatic hydrolysate reached up to 5.52 g/L, which was 7.4 times higher than that from a control of glucose-based media.关键词
