“…In recent studies, white-rot fungi inducing lignin degradation has been used to increase the digestibility of lignocellulose by ruminants [10][11][12]. It is possible, however, that ruminal digestion of woody lignocellulose is accelerated by exposing woody celluloses.…”

The aim of the present study was to evaluate in vitro and in vivo ruminal fermentation of micronised wood powder in beef cattle. Micronised wood powder was prepared by pulverizing sapwood of Japanese cedar to a mean particle size of 52 µm. Ruminal fluid from four beef cows was anaerobically incubated with different amounts of micronised wood powder (50, 100, 200, or 400 mg per 30 ml rumen fluid) for 24 hours at 39°C. In the in vivo experiment, four cows were fed micronised wood powder for four weeks in a crossover design. During the initial feeding period of seven days, micronised wood powder was gradually increased to the equivalent to 0.3% of body weight, and then animals were fed micronised wood powder for three weeks at this level. In batch fermentation, total concentrations of volatile fatty acid were increased by micronised wood powder supplementation except at 50 mg. This response was mainly attributable to increased concentrations of the major volatile fatty acids of acetate, propionate, and butyrate. However, volatile fatty acid production from micronised wood powder by in vitro ruminal fermentation was low and limited, even when the supplemented levels were increased to 400 mg. The ruminal fermentability of micronised wood powder was shown by the lack of change in the volatile fatty acid profile during in vivo ruminal fermentation. Therefore, the present study found that ruminal microorganisms enable fermentation and digestion of lignocelluloses in micronised wood powder directly for volatile fatty acid production. However, further consideration of micronised wood powder, such as improvement in particle size or lignin, is needed to accelerate the fermentation kinetics of micronised wood powder in the rumen.

“…Most of the white-rot fungi degrade lignin and cellulose simultaneously. A selective white-rot fungus, Ceriporiopsis subvermispora is known to selectively degrade lignin in softwood and hardwood (Okano et al, 2005) and Phanerochaete chrysosporium, Pleurotus ostreatus, Ceriporiopsis subvermispora, Cyathus stercoreus can be used to increase the digestibility of paddy straw (Taniguchi et al, 2005).…”

“…Phanerochaete chrysosporium, Pholiota nameko, Dichomitus squalens, Lentinus edodes, Ceriporiopsis subvermispora, Ganoderma spp., and Trametes versicolor (e.g. Zadrazil et al 1996, Gao et al 1997, Chantaraj 2000, Basu et al 2002, Okano et al 2005. Usually in such studies, improvement of in vitro digestibility of lignocellulosic material (IVDMD; tests in which a release of glucose from the sample by cellulases is measured) is analysed as an index to judge the improvement of the waste material for animal feeding after fungal fermentation.…”

“…Numerous lignocellulosic and agricultural waste materials were proven to be a potential material for fungal bio-upgrading as fodder, including the above mentioned wheat straw (Jalč et al 1998, Fazaeli et al 2004a, corn stalk, rice straw, cotton stalk (Kerem et al 1992, cottonseed hull , viticulture wastes , red cedar wood (Okano et al 2005), waste cellulose fibres (Nikolov et al 2000), and others (see recent reviews: Jalč 2002, Villas-Bôas et al 2002. Studied fungi included not only the edible and well studied white-rot Pleurotus ostreatus (Cohen et al 2002;Fig.…”
