摘要: To minimize environmental contamination and waste of resources, distillers’ grain (DG) from the Chinese liquor industry was used to produce reducing sugars for Bacillus thuringiensis cultivation. Four different pretreatments, using sodium hydroxide (0.5–2% w/v, 50–121 °C, 1 h), calcium (0.2–4% dilute sulfuric acid hot water (50–121 were investigated in order determine optimal method degrading cellulose DG monomeric sugars. Enzymatic hydrolysis fermentation followed each pretreatment method. The results showed that highest yield obtained by 2% treatment at 121 °C h (giving 313 g/kg DG), which significantly higher (p < 0.001) than yields other methods. spore count achieved this with addition supplements. utilization study provides a plentiful carbon ...
