Recently, biofuel produced from marine biomassas abundant and renewable energy source have brought considerable attention. The marine biomass primarily consists of polysaccharides, protein and lipid. These polysaccharides are usually depolymerized into mono-sugars by thermo-chemical or enzymatic hydrolysis. In order to obtain high mono-sugar yield, high temperature and catalyst are applied in hydrolysis process. It causes the formation of fermentation inhibitors such as hydroxymethylfurfural, formic acid, acetic acid, furfural, etc. These compounds affect cell growth, sugar uptake, and metabolic pathway. A number of methods have been applied to separate fermentation inhibitors from lignocellulosic hydrolysate. However, the study of separation of fermentation inhibitors from hydrolysate derived from marinebiomass was not properly carried out. Here, we demonstrate the potential of separating these inhibitors from hydrolysate for enhancing the bioethanol fermentation.
