1-allyl-3-methylimidazolium chloride pretreatment of seaweed industrial waste for bioethanol conversion
Alginate industrial waste, that is, floating residue (FR) obtained from Laminaria japonica, was investigated in this study on saccharification for bioethanol conversion from cellulose. Pretreatment, as a key link but currently a bottleneck, was addressed by 1-allyl-3-methylimidazolium chloride (AMIMCl), which is considered a preferable pretreatment solvent form among various room temperature ionic liquids. Effects of AMIMCl pretreatment conditions were detected in moderate ranges of low energy consumption through single factor tests, incubation temperature, incubation time, and the solid-to-AMIMCl ratio (w/w), respectively. Further, the scanning electron microscopy and X-ray powder diffraction were used to study the alteration of structure and crystal form of FR after pretreatment. Meanwhile, it was shown that FR by AMIMCl pretreatment was capable of achieving a high glucose conversion rate with a lower content of cellobiase, which was in favor of the fermentation process. In the simultaneous saccharification and fermentation process, AMIMCl pretreatment could improve the bioethanol conversion rate to 91.60% in a shorter reaction time when compared with dilute sulfuric acid pretreatment. Thus, AMIMCl pretreatment has remarkable potential prospect for use as a new biotechnology technique in the marine biomass field.
