     cellulose hydrolysis is the rate-limiting step in anaerobic digestion. in the present study, waste paper was used as a model of cellulosic biomass and was pretreated with rumen fluid prior to methane production. to achieve a high methane yield, the reaction time of the pretreatment was examined. waste paper was soaked with rumen fluid for 6 and 24 h at 37 °c. various volatile fatty acids, especially acetate, were produced by the pretreatment. semicontinuous methane production was carried out over a 20-day period. the best daily methane yield was obtained by the 6-h pretreatment. the amount was 2.6 times higher than that of untreated paper, which resulted in 73.4% of the theoretical methane yield. during methane production, the cellulose, hemicellulose and lignin degradabilities were improved by the pretreatment. pretreatment by rumen fluid is therefore a powerful method to accelerate the methane yield from a cellulosic biomass.
