Rice straw is one of the most abundant
lignocellulosic feedstock in the world. In Asia, it is
produced about 667.6 million tons annually. Wen-
Heng et al (2012) [39] used rice straw as raw
material to produce ethanol with single
fermentable strain, P. sitpitis has been studied.
Without any nutritional supplementation, the
ethanol yield were around 0.45~0.5 g/g in the rice
straw hydrolysates. Particularly, the high ethanol
yield form rice straw hydro lysate mixture by P.
stipits showed the potential of developing the co-
fermentation process. The lower constitutes of
lignin and acetyl group in the rice straw is reflects
the less inhibition during hydrolysate
fermentation. Overliming employed was also
effective in removing phenolic compounds. These
results revealed a promising perspective to
develop more attractive ethanol production
process from rice straw as raw material using
P.stipitis.
