바이오에탄올 생산을 위한 해조류의 가수분해 방법에 대한 고찰

Sugar, starch and lignocellulosic biomass has been mainly used as raw materials for the production of the bioethanol. However, the sharp fluctuation of grain prices, a threat of world famine, and hardly biodegradable substance like lignin contained in lignocellulosic materials make the pre-processing of the biomass complicated in several aspects. As a result, the focus of attention has now shifted to the ‘third biomass’ such as algae, which has a high value of energy recovery. In this study, a kind of macroalgae and its characteristic were surveyed and then, the physical, biological, chemical, combined, and hydrothermal pretreatments for its hydrolysis were deeply considered. Consequently, the macroalgae could be more effectively hydrolyzed at the combined process such as the hydrothermal-chemical or biological treatment, chemical-biological treatment and so on than the single process like the biological pretreatment.
