The abilities of litter‐decomposing fungi (LDF) to remove lignin from leaves of a perennial grass, Miscanthus sinensis, were examined under pure culture conditions. A total of 12 fungal isolates were tested, including eight isolates of seven basidiomycete and one ascomycete species that are ligninolytic on tree leaf litter and four isolates of another ascomycete species, Nigrospora sphaerica, obtained from M. sinensis leaves. Mass loss of leaves caused by the 12 isolates ranged from 4.7 to 43.1% of the original leaf mass. Trametes versicolor caused the greatest mass loss of lignin, followed by Marasmius sp. and Gerronema nemorale, whereas Mycena polygramma and the four isolates of N. sphaerica had limited abilities to cause mass loss of lignin. Trametes versicolor caused the greatest mass loss of total carbohydrates, followed by Marasmius sp., two isolates of N. sphaerica, and G. nemorale, whereas Pseudoclitocybe cyathiformis, Coccomyces sp., and Clitocybe gibba had limited abilities to cause mass loss of total carbohydrates. Mass loss of lignin was significantly and positively correlated with mass loss of leaves for the seven isolates that showed marked ligninolytic activities. In separate experiments, leaves previously partly decomposed by three ligninolytic fungi were used in pure culture tests to evaluate the effects of the pretreatment of grass leaves by ligninolytic fungi on subsequent utilization of substrates by fungi with limited ligninolytic activities. The pretreatment of M. sinensis leaves with three ligninolytic fungi generally suppressed the subsequent decomposition of lignin, total carbohydrates, or both by N. sphaerica. The results demonstrate that ligninolytic LDF are capable of removing lignin effectively from grass leaves.

“…Little attention has been paid to biodegradation of tannin-rich materials. White rot fungi are known to degrade lignin (Zadrazil 1980;Kamra and Zadrazil 1986;Rolz et al 1986;Kewalramani et al 1988;Kerem et al 1992). As lignins and tannins are structurally and biosynthetically related polymers whose monomer units are phenols, we studied the degradation of tannins in oak leaves using Sporotrichum pulverulentum, a white rot fungus.…”

Fermentation of oak leaves with Sporotrichum pulverulentum decreased the contents of total phenols and condensed tannins by 58 and 66% respectively in 10 d. The protein precipitation capacity decreased by 65%. Further increase of fermentation time up to 40 d did not increase substantially, the tannin degradation. Following fermentation, neutral detergent fibre, acid detergent fibre, hemicellulose, cellulose and lignin decreased by 12–16%, 8–10%, 31–51%, 0.3‐3% and 14–15% respectively. The loss in dry matter was from 17–21%. The in sacco dry matter digestibility of the fermented leaves was 17% compared to 27% for the unfermented leaves.

An overview of the basic technology to produce bioethanol from lignocellulosic biomass is presented in this context. The conventional process includes two main steps. First, lignocellulose must be pretreated in order to remove lignin and enhance the penetration of hydrolysis agents without chemically destruction of cellulose and hemicellulose. Second, the pretreated material is converted to bioethanol by hydrolysis and fermentation. Some typical published studies and popular processing methods in attempts to improve the biomass conversion to bioethanol and increase the cost-effectiveness are also introduced briefly. Herein, the refinery of the resulted raw bioethanol mixture to obtain higher concentrated solution is not regarded.
