Abstract
본 연구에서는 해양 거대조류 중 홍조류에 속하는 꼬시레기(Gracilaria verrucosa)로부터 malonic acid를 사용하여 열수 전처리 조건(전처리 온도, 촉매 농도, 고액비, 전처리 시간)에 따른 전처리와 효소가수분해를 통한 바이오슈거(환원당) 생산 가능성을 조사하였다. 300 mM malonic acid, 1:20 고액비 조건에서 130 °C에서 60분간 전처리를 수행하여 49.2%의 환원당 수율을 얻었다. 전처리 반응 후 이어진 효소 가수분해를 통하여 64.5%의 수율을 확보하였다.
In this study, the effects of malonic acid-catalyzed pretreatment on the subsequent enzymatic hydrolysis of red macro-algae Gracilaria verrucosa for production of biosugar (total reducing sugar) were investigated. In the hydrothermal pretreatment condition of 300 mM malonic acid, 1:20 solid-to-liquid ratio at 130 oC for 60 min, a 49.2% biosugar yield was achieved. Moreover, by subsequent enzymatic hydrolysis after pretreatment, maximum yield of 64.5% was achieved.
