The potential for recombinant cellulases from fungi to hydrolyze oil palm empty fruit bunches (OPEFB) into simple sugars
was investigated. A mixture of two recombinant enzymes consisting of a cellobiohydrolase from Trichoderma reesei and an
endoglucanase from Aspergillus niger, was evaluated for OPEFB hydrolysis. The development of A. niger endoglucanase
has been described previously. In this work, the development of a recombinant cellobiohydrolase and the activity of this
enzyme mixture towards OPEFB hydrolysis were described. To obtain recombinant cellobiohydrolase, the cDNA encoding
for cellobiohydrolase, cbhII, was isolated from the T. reesei strain M5, and the gene was expressed in the methylotrophic
yeast, Pichia pastoris. Partially purified CbhII demonstrated optimum activity at 50°C and pH 5.0. This enzyme was shown
to hydrolyze Avicel at a concentration of 0.486 U/mg under optimum conditions. Hydrolysis of pretreated OPEFB using
CbhII and endoglucanase EglA showed that the total reducing sugar produced was higher in the enzyme mixture reaction
than were produced in an individual enzyme reaction. Addition of β-glucosidase and an enzyme cofactor significantly increased
enzyme activity and OPEFB cellulose hydrolysis. This study demonstrated the capability of an enzyme mixture to produce
sugars from oil palm lignocellulosic waste. |
