Abstract | The objective of the study was to test the feasibility of produci ng methane gas by microbial anaerobic fermentation of three readily available raw materials - nightsoil, water hyacinth and rice straw - mixed at ratio of 1:1:2 (dry weight proportions). The latter two materials were prepared by finely grinding prior to mixing with the nightsoil and the environmental conditions necessary for bacterial growth and multiplication were provided. After five months in a controlled temperature of 30 ±2°c, a batch digester of 15 litres had reached its potential of biogas production at 300 litres per kilogram of dry mass. The average methane content was found t o be 62.6 per cent. |
