prospek enzim anoldan lignoselulase pada produksi bioet


PROSPECT OF ENZYME AND LIGNOCELLULOSE WASTE FOR BIOETHANOL PRODUCTION
ABSTRACT
Substitution bioethanol as one of energy source has been selected as an alternative source
for the fossil fuel substitution. The agricultural and industrial waste can be used for the production of
bioethanol. The main component in those waste materials is lignocellulose that contained cellulose,
hemicellulose and lignin. Lignocellulose will be the main source for bioethanol production in the long
term. Several enzymes have been recorded in degrading lignocellulose which are cellulolytic,
hemicellulolytic as well as lignolytic. The main enzyme which has the most important role in
bioethanol production are complex enzymes which degrade lignocellulose. Bioethanol production is
much affected by raw materials composition, type of microorganisms, and the fermentation condition
used.
Key words: lignocellulose, cellulase, hemicellulase, lignin degrading enzyme, bioethanol
