Summary A comparison was made between the effectiveness ofPachysolen tannophilus andCandida brassicae as fermenting organisms in the simultaneous saccharification and fermentation (SSF) process. The substrates were alkalipretreated rice straw, corn. cobs and simulated hydrolysates containing D-glucose:D-xylose in ratios comparable to rice straw or corn cobs. Under these pretreatment and SSF conditions,Pa. tannophilus gave higher ethanol yields thanC. brassicae in all cases, producing at least 0.23 g/g from corn cobs, 0.17 g/g from rice straw, 0.43 g/g from simulated corn cob hydrolysate and 0.47 g/g from simulated rice straw hydrolysate. The relatively high ethanol yields ofPa. tannophilus came from the utilization of both glucose and xylose, whileC. brassicae only utilized glucose.
