MG-60 was the good producer of ethanol from cellulose. ► Kraft pulp was directly converted into ethanol without addition of cellulase. ► Newspaper was directly converted into ethanol. ► Hexoses were completely assimilated by MG-60 with high ethanol yields. ► Xylose was also completely assimilated with high ethanol yields.</P> <P><B>Abstract</B></P><P>White-rot fungus <I>Phlebia</I> sp. MG-60 was identified as a good producer of ethanol from several cellulosic materials containing lignin. When this fungus was cultured with 20g/L unbleached hardwood kraft pulp (UHKP), 8.4g/L ethanol was produced after 168h of incubation giving yields of ethanol of 0.42g/g UHKP, 71.8% of the theoretical maximum. When this fungus was cultured with waste newspaper, 4.2g/L ethanol was produced after 216h of incubation giving yields of ethanol of 0.20g/g newspaper, 51.1% of the theoretical maximum. Glucose, mannose, galactose, fructose and xylose were completely assimilated by <I>Phlebia</I> sp. MG-60 with ethanol yields of 0.44, 0.41, 0.40, 0.41 and 0.33g/g of sugar respectively. These results indicated that <I>Phlebia</I> sp. MG-60 was a good candidate for bioethanol production from cellulosic materials.</P>
