Abstract

APPLICATION OF CRUDE CELLULASE ENZYMES FROM CORN COB (Zea mays L) IN ETHANOL PRODUCTION BY SIMULTANEOUS SACCHARIFICATION AND FERMENTATION METHOD (SSF). Abundant corn cobs as a by-product from the processing of corn industry, provides an opportunity to be used as a substrate in the production of crude cellulase enzymes. Crude cellulase enzymes from corn cobs later applied to the production of ethanol by simultaneous saccharification and fermentation (SSF) using corn cob as raw material. The purpose of this research is to study the effect of crude cellulase enzymes volume, the performance of crude cellulase enzymes in producing ethanol and compare its performance with crude commercial enzymes. The research was composed of two phases, namely pretreatment of corn cobs, and fermentation. Dried corn cobs were grinded to powder having size of 12 mesh, and treated with steam explosion for 60 minutes. For the fermentation process, nutrients, crude cellulase enzymes and cultures of Saccharomyces cerevisiae was added to the pretreated powder. The fermentation was carried out at 30oC for 120 hours, while the observations were made every 24 hours. The results showed that ethanol produced using crude cellulase enzymes and crude commercial enzymes are 1.28% and 2.89% respectively.
