제목 Improved tolerance of the cellular toxicity from lignocellulosic hydrolysate in engineered Corynebacterium glutamicum
초록 Acid-pretreatment of lignocellulosic biomasses produced fermentable sugars and cellular inhibitors such as Furfural, HMF, etc. We developed the strain capable of tolerant to the inhibitors. Initially, we focused the effect of the inhibitors to Corynebacterium glutamicum. Cellular growth was retarded under various conditions of cellular inhibitors, including furfural that is a derivative of furan in the hydrolysate. C. glutamicum grown with furfural showed over 2-folds of reactive oxygen species stresses. Moreover, the conversion rate of furfural was calculated. We have engineered C. glutamicum by overexpressing the target genes. When we cultivated the engineered strains with furfural, they showed improved the growth rate. Several metabolic engineering approaches could further improve the tolerance in C. glutamicum.
