This study was to increase glucose conversion yield of marine algae, Ulva pertusa Kjellman. Ultrasonification-assisted liquefaction process showed effecting destruction of polysaccharides under following conditions: 120W, 250W, 340W input power for 60min and at a frequency of 20kHz only by using water. The optimal condition of ultrasonification pretreatment was determined as 250W for 60min, having higher sugar yields as 12.2(% w/w), compared to 10.2~11(% w/w) for 700W and 1300W, which indicates that this process could increase the sugar conversion yields up to 10~15% of brown seaweed. Ulva pertusa Kjellman was estimated to contain ca. 6.7% (w/w) of cellulose and 16.8% (w/w) of hemicelluloses, and the hydrolysates from this process was also easily digested only 5FPU/ml of cellulase. About 97% of cellulose was converted into glucose under this condition, which implied that this ultrasonification-assisted liquefaction could be employed to effectively hydrolyze celluloses of marine algae. Consequently, the improvement is primarily attributed to the ultrasonification process for the enhanced enzyme activity of cellulose hydrolysis.
