Abstract
This study aimed at evaluating the requirement of nitrogen sources by the yeast Scheffersomyces stipitis NRRL Y-7124 to produce ethanol from xylose based-media. Different nitrogen sources were evaluated, which were used to supplement a defined xylose-based medium and also the hemicellulosic hydrolysate produced from rice straw. Interesting results were achieved, which revealed that it is important to add nitrogen sources to the medium to achieve efficient ethanol production by this yeast strain. However, from rice straw hydrolysate medium, the nitrogen supplementation was not necessary, suggesting that this hydrolysate contains enough nitrogen source to provide an efficient xylose conversion to ethanol.
