고정된 S. coreanus를 이용한 다시마로부터 바이오에탄올 생산 = Bioethanol Production from Laminaria japonica by Immobilized Saccharomyces coreanus

다국어 초록 (Multilingual Abstract)

Bioethanol was produced from Laminaria japonica hydrolystaes by sequential acidic (0.108 N HCl)/distilled water and enzymatic hydrolysis (Celluclast® 1.5 L) using Saccharomyces coreanus immobilized into/on aluminum silicate. Reducing sugar were hydrolyzed 140.5 and 122.7 mg/g-dry biomass under a acidic-enzymatic condition and a distilled waterenzymatic condition, respectively. In addition, the 8 repetition batch fermentations were carried out with the immobilized S. coreanus to verify the advantage of immobilization cell. As a result, we can obtain the ethanol of 12.1 ~ 24.3 mg/gdry biomass, and reuse the support, aluminium silicate, for 8 repetition batch fermentations without any breakdown.
