✦ Synopsis


Cellobiose and glucose were produced using an enzyme (cellulase from ¹richoderma viride) reaction from the crude "ber unit (CFU) separated from Wakame seaweed (;ndaria pinnati,da). The method for separation involved adding sodium carbonate (Na CO ) to desalted stalks of wet Wakame. The wet CFU was pulverized using a centrifugal grinder after lyophilization. The enzyme reaction used the CFU powder as a substrate. The maximum concentration of cellobiose and glucose reached 56$2.0 and 130$0.2 mg/g, respectively. The total cellulose included in this CFU was determined to be about 70%. The sugar recovery from cellulose in the CFU was 20%. Although glucose was detected when micro-crystalline cellulose was used as a substrate, cellobiose and glucose were detected when CFU powder was used as a substrate.
