Abstract Agricultural by-products such as corn stover (CS) are abundantly available in many countries; however, its high content of neutral detergent fiber (NDF) and lignin (L) and low protein content, causes low digestibility and nutrient availability for ruminants. The production of edible fungi could improve the digestibility of the CS because fungi can break down the cross-links between cell wall components. The aim of the study was to evaluate the effect of the invaded CS-based substrate used in the production of 21 white rot fungi of the species: Auricularia sp (Auri), Ganoderma sp (Gano), Hericium sp (Heri), Lentinula edodes (LC, L5, L9, L15, L21), Pleurotus eryngii (Pe-PQ, Pe-MB), Pleurotus djamour (Pd-Pro, Pd-UTMR) and Pleurotus ostreatus (Po-IAP, Po-Psma, Po-P14, Po-POS, Po-IE202, Po-JP, Po-P35, Po-P38, Po-Sfco) on crude protein (CP), NDF and L content and in vitro dry matter digestibility (IVDMD). The variables were analyzed in a completely randomized design with the MIXED procedure of SAS and the comparison of the means was made with the Tukey analysis. For CP, a significant increase (P < 0.05) was observed from 10% (Pe-MB) to 41% (LC) in comparison with the substrate without inoculation (C). There was a decrease (P < 0.05) of NDF from 2% (LC) to 10% (Pd-PRO) against C. Fungal treated CS had no effect on L (P < 0.05) as compared to C. Treatments increased (P < 0.05) IVDMD from 3% (L15) up to 36% (Po-POS) for all fungal strains, except for Pe-PQ and Po-Sfco in comparison with C. There was a positive correlation (r2=0.21, P < 0.05) between CP and IVDMD. An equation was obtained to predict IVDMD [IVDMD=0.40578 + 358.38(%ADF)–358.02(%NDF)+358.17(%HEM)–0.3211(%DM), R2=0.32 (P < 0.05)]. In conclusion the mycelial invasion of white rot fungi on a CS-based substrate, increased CP content, decreased NDF and improved IVDMD, making it a viable option to increase the digestibility of CS.

In Sacco

Fungal treatment has been recently considered as a promising method for improving the nutritive value of straw (Zadrazil et al., 1997). Several studies have been conducted to identify species of white-rot fungi for assessing their ability to improve the nutritive value of straw (Yamakamwa et al., 1992). Since there are many species of fungi in nature, there is an interest in characterising of some species. The objectives of this experiment were to study the effect of five Pleurotus fungi on the chemical composition, in vitro digestibility and in sacco degradability of wheat straw and evaluate their effect in upgrading the nutritive value of lignicellulosic materials.

A study was conducted to evaluate the effect of biological treatments of sugarcane bagasse (SCB) and rice husk (RH) with three strains of white-rot fungi (WRF) (Pleurotusostreatus (Po), Pleurotusflorida (Pf) and Trichodermaviride (Tv) and effective microorganism (EM) on the chemical composition and in-vitro digestibility. The experiment consisted of 2x5 factorial arrangements, two levels of feed (SCB and RH) and five levels of biological treatments (Control, Po, Pf, Tv, and EM).Treatment of RH with EM, Tv, Po and Pf, significantly increased crude protein content from 7.90% in untreated to 7.92, 10.46, 10.61 and 11.35%, respectively. The corresponding increase in CP% of sugarcane from 2.61% was 3.41, 5.96, 5.89 and 5.95%.Treatments significantly (P<0.001) decreased neutral detergent fiber, acid detergent fiber, acid detergent lignin cellulose and hemicelluloses contents with the lowest value recorded for Tv. The IVOMD, IVDMD and metabolizable energy (ME) were significantly (P<0.001) increased. In conclusion, the study indicates that treatment of RH with Trichodermaviride and SCB with EM is more effective than others in improving the nutritive value of the roughages. We suggest evaluation of the treated roughages on animal performance.

Wood Decay Fungi

Influences of eight saturated aliphatic acids (C5–C10, C12, and C16) on basidiospores of four isolates of wood-decay fungi (Poria tenuis and Trametes hispida, white rot fungi, and two isolates of the brown rot fungus Gloeophyllum trabeum) were observed in vitro. Spore responses after 24 h on malt extract agar containing 10, 102 or 103 ppm of each acid included normal germination, delay of germ tube emergence, vacuolation and degeneration of spore cytoplasm, and prevention of germ tube development without spore destruction. Acids of chain length C5–C10 prevented spore germination and killed spores of all fungi at concentrations of 20–50 ppm in media, whereas other acids tested were less active. Spore germination assay of decay fungi may prove useful as a screening tool to compare potency of wood preservatives.

The in vitro wood decay abilities of Ganoderma lucidum (W. Curt.: Fr.) Karst. and G. tsugae Murr. were studied using the following woods in agar block decay chambers: Vitis vinifera L., Quercus hypoleucoides A. Camus, Prosopis velutina Woot., Abies concolor (Gord. & Glend.) Lindl. ex. Hildebr., and Pseudotsuga menziesii (Mirb.) Franco. Grape wood lost the most weight while mesquite the least. Ganoderma lucidum isolates generally caused greater weight loss of all woods than did G. tsugae isolates. The range of the percent weight losses varied with the wood. Both Ganoderma species caused simultaneous decay in all woods. However, chemical analyses of the decayed blocks indicated that selective delignification by both species also occurred in grape and white fir blocks. Chemical analysis of the decayed oak blocks indicated the percentages of lignin and holocellulose were not statistically different from the controls. However, there was a trend towards delignification. The analyses of the Douglas-fir blocks indicated only simultaneous decay. Scanning electron microscopy demonstrated selective delignification and simultaneous decay of all woods tested. However, the extent of the delignification differed among the wood species. Delignification appeared mainly in areas of tracheids or fiber tracheids, while the rays were simultaneously decayed.
