Twelve white-rot fungi were grown in solid-state culture on lemon grass (Cymbopogon citratus) and citronella (Cymbopogon winterianus) bagasse. The two lignocellulosic substrates had 11% permanganate lignin and a holocellulose fraction of 58%. After 5 to 6 weeks at 20 degrees C, nine fungi produced a solid residue from lemon grass with a higher in vitro dry matter enzyme digestibility than the original bagasse; seven did the same for citronella. The best fungus for both substrates was Bondarzewia berkeleyi; it increased the in vitro dry matter enzyme digestibility to 22 and 24% for lemon grass and citronella, respectively. The increases were correlated with weight loss and lignin loss. All fungi decreased lignin contents: 36% of the original value for lemon grass and 28% for citronella. Practically all fungi showed a preference for hemicellulose over cellulose.
12 种白腐真菌在固体培养柠檬草（Cymbopogon citratus）和香茅（Cymbopogon winterianus）蔗渣上生长。这两种木质纤维素基质的高锰酸盐木质素含量为 11%，全纤维素含量为 58%。在 20°C 下培养 5 至 6 周后，有 9 种真菌从柠檬草中产生了固体残余物，其体外干物质酶消化率高于原始蔗渣；7 种真菌对香茅也有同样的效果。对这两种基质来说，最好的真菌是Bondarzewia berkeleyi；它分别将柠檬草和香茅的体外干物质酶消化率提高到 22%和 24%。这种增加与失重和木质素损失有关。所有真菌都降低了木质素含量：柠檬草和香茅的原始值分别降低了 36%和 28%。实际上，所有真菌都表现出对半纤维素的偏好超过纤维素。
