Combination of dilute acid and ionic liquid pretreatments of sugarcane bagasse for glucose by enzymatic hydrolysis

Loss of hemicellulose and inability to effectively decrystallize cellulose, result in low yield and high cost of sugars derived from biomass. Dilute sulfuric acid pretreatment could easily remove most of hemicellulose as sugars. 继续阅读“Combination of dilute acid and ionic liquid pretreatments of sugarcane bagasse for glucose by enzymatic hydrolysis”

离子液体处理后的纤维素和小桐子果壳的稀酸水解液用于2,3-丁二醇发酵

为了充分利用原料和获得具有高浓度糖的生物质水解液,微晶纤维素和小桐子果壳在经过离子液体([BMIM]Cl)处理后再进行稀酸水解。相比于没有经过预处理的微晶纤维素,离子液体处理后的纤维素在水解后,还原糖的得率和浓度提高了139%, 水溶性产物的得率提高了128%。 继续阅读“离子液体处理后的纤维素和小桐子果壳的稀酸水解液用于2,3-丁二醇发酵”

Production of 2,3-butanediol from cellulose and Jatropha hulls after ionic liquid pretreatment and dilute-acid hydrolysis

To make full utilization of raw material and achieve high concentration of sugars in the hydrolysate of biomass, microcrystalline cellulose and Jatropha hulls were pretreated by IL1-butyl-3-methylimidazoliuma chloride ([BMIM]Cl) before their subsequent dilute sulfuric acid hydrolysis. 继续阅读“Production of 2,3-butanediol from cellulose and Jatropha hulls after ionic liquid pretreatment and dilute-acid hydrolysis”
