dc.description.abstract | The performance of green liquor pretreatment using Na2CO3 and Na2SO3 and its optimization for whole rice waste biomass (RWB) was investigated. Incubation of Na2CO3-Na2SO3 at a 1: 1 ratio (chemical charge 10%) for 12% RWB at 100 degrees C for 6 h resulted in maximum delignification (58.2%) with significant glucan yield (88%) and total sugar recovery (545 mg/g of RWB) after enzymatic hydrolysis. Recovery and reusability of the resulting chemical spent wash were evaluated to treat RWB along with its compatibility for enzymatic digestibility. Significant hydrolysis and lignin removal were observed for up to three cycles; however, further reuse of Na2CO3 and Na2SO3 lowered their performance. Significant 2,3-butanediol (BDO) was produced by Klebsiella pneumoniae KMK-05 with the RWB enzymatic hydrolysate from each pretreatment cycle. BDO yield achieved using RWB-derived sugars was similar to those using laboratory-grade sugars. This pretreatment strategy constitutes an ecofriendly, cost-effective, and practical method for utilizing lignocellulosic biomass. (C) 2016 Elsevier Ltd. All rights reserved. | - |
