The effects of temperature (35 and 55 degrees C), influent volatile solids (VS) concentration (So equal to 43, 64, 82, 100, 128 kg VS/cu.m) and hydraulic retention time (HRT equal to 4, 5, 8, 10, 15, and 25 days) on methane (CH/sub 4/) production from cattle waste were evaluated using 3-d cu.m laboratory scale fermentors. The highest CH/sub 4/ production rate achieved was 6.11 cu.m CH/sub 4//cu.m fermentor/day at 55 degrees C, four days HRT, and So equal to 100 kg VS/cu.m. Batch fermentations showed an ultimate CH/sub 4/ yield (Bo) of 0.42 cu.m CH/sub 4//kg VS fed. The maximum loading rates for unstressed fermentation were 7 kg VS/cu.m/day at 35 degrees C and 20 kg VS/cu.m/day at 55 degrees C. The kinetic parameter (K, an increasing K indicates inhibition of fermentation) increased exponentially as So increased, and was described by : K equal to 0.8 plus 0.0016e 0.06So. Temperature had no significant effect on K for So between 40 and 100 kg VS/cu.m. The above equation predicted published K values for cattle waste within a mean standard error of 7%. (Refs. 11).
