Abstract

The aim of this work was to compare the impact of inoculation density on the rate of cellulose hydrolysis by a rumen derived culture with that of a microbial enrichment from an organic waste anaerobic digester. The results showed a linear relationship between the mass of biomass at the start of the first order degradation phase (Xo) and the first order hydrolysis rate (r) for both rumen inoculated and leachate inoculated cellulose digestions and that the slopes of these relationships were not distinguishable. This suggested that differences in the microbial community, media and other environmental factors had a lesser impact on the hydrolysis rate compared to the effect of the number of cell..
