چکیده انگلیسی
Juncus maritimus contains (41.5 ± 0.3)% cellulose and (31.34 ± 0.2)% hemicellulose on dry solid (DS) basis and has the potential to serve as a low cost feedstock for ethanol production. Dilute acid or freezing/thawing pretreatments and enzymatic sacchariï¬cation were evaluated for conversion of halophyte plant from J. maritimus cellulose and hemicelluloses to monomeric sugars. The maximum concentration of released glucose from J. maritimus (53.78 ± 3.24) g Lâ1) by Freezing/thawing pretreatment and enzymatic sacchariï¬cation (55 °C, pH 5.0 and 48 h) using CellicCTec2 from Novozymes and (49.14 ± 5.24) g Lâ1 obtained by dilute acid pretreatment. The maximum yield of ethanol from acid pretreated enzyme sacchariï¬ed J. maritimus hydrolyzate by Saccharomyces cerevisiae strain was (84.28 ± 5.11)% of the theoretical yield with a productivity of (0.88 ± 0.16)g Lâ1 hâ1. It was (90.87 ± 1.94)% of the theoretical yield with a productivity of (1.04 ± 0.10) g Lâ1hâ1 for freezing/thawing pretreated plant and enzymatic hydrolysis by CellicCTec2.
