Sumario:Efficient bio-ethanol production from napiegrass (Pennisetum purpureum Schumach) was investigated. A low-moisture anhydrous ammonia (LMAA)-pretreated napiegrass was subjected to simultaneous saccharification and co-fermentation (SSCF), which was performed at 36°C using Escherichia coli KO11, Saccharomyces cerevisiae, cellulase, and xylanase. It was found that use of xylanase as well as the LMAA-pretreatment was effective for the SSCF. After the SSCF for 96 h, the ethanol yield reached 74% of the theoretical yield based on the glucan (397 mg g(-1)) and xylan (214 mg g(-1)) occurring in dry powdered LMAA-pretreated napiergrass.
