Abstract:
As a novel alternative lignocellulosic feedstock for biorefinery, Jerusalem artichoke stalks (JAS) has different cellulosic compositions from the stalks of agriculture crops, however, studies on the bioconversion of JAS are still limited. It is crucial to optimize the pretreatment technology of JAS and to further study fuel ethanol fermentation from JAS hydrolysate with recombinant Saccharomyces cerevisiae. In this work, JAS was pretreated using NaOH-H2O2, instant catapult steam explosion (ICSE), and sequential ICSE and NaOH-H2O2 treatment. It was found that NaOH-H2O2 pretreatment method was the best for the pretreatment of JAS. The results also showed that washing the pretreated JAS for only one time was sufficient, significantly benefited the hydrolysis and fermentation process, and reduced waste water. Finally, separated hydrolysis and fermentation of pretreated JAS with high solid loading by feeding of both JAS substrate and enzyme was investigated. When the solid loading reached 30% (m/V), 143.6 g/L glucose and 36.2 g/L xylose were obtained after 72-hour hydrolysis. When the hydrolysate was subject to fermentation by employing the recombinant S. cerevisiae strain LX03, ethanol titer of 66.2 g/L (8.27%, V/V) was achieved with total sugar consumption ratio of 86.9%. The results in this study provide insights for the improvement of bioconversion efficiency of JAS and high titer cellulosic ethanol production by recombinant S. cerevisiae using JAS.
