白腐担子菌Peniophora cinerea和Trametes suaveolens可以利用己糖生产乙醇。虽然T.在好氧和半好氧条件下，灰葡萄球菌均能产生乙醇，并能同化葡萄糖、甘露糖、果糖、半乳糖、蔗糖、麦芽糖和纤维二糖，乙醇产量分别为0.41、0.45、0.44、0.19、0.41、0.44和0.45 g/g己糖。T.甜菊糖含量分别为0.39、0.3、0.13、0.2、0.37、0.35和0.31 g乙醇/g己糖。此外，P.cinerea表现出同时糖化和发酵无定形纤维素。
The white-rot basidiomycetes, Peniophora cinerea and Trametes suaveolens, can produce ethanol from hexoses. Although T. suaveolens produced negligible amounts of ethanol under aerobic conditions, P. cinerea produced ethanol under both aerobic and semi-aerobic conditions and assimilated glucose, mannose, fructose, galactose, sucrose, maltose and cellobiose with yields of ethanol of 0.41, 0.45, 0.44, 0.19, 0.41, 0.44 and 0.45 g per g hexose, respectively. The corresponding results for T. suaveolens were 0.39, 0.3, 0.13, 0.2, 0.37, 0.35 and 0.31 g ethanol/g hexose. Furthermore, P. cinerea exhibited simultaneous saccharification and fermentation of amorphous cellulose.
