Abstract

Anaerobic digestion of water hyacinth may reduce the nuisance value and water pollution problem created by this waterweed and considerable amount of biogas can be obtained. The rate of biogas can be enhanced under a short period by giving certain fungal treatment prior to anaerobic digestion. Pretreatment of water hyacinth with Phanerochaete chrysosporium and Phanerochaete chrysosporium + pyrogallol red was found to increase the amount of gas production within short Hydraulic Retention Time (HRT), through solublization of lignocellulosic biomass in water due to which choking problem of the biogas plant could be sorted out. This paper deals with the efficient utilization of water hyacinth for fuel and fertilizer. Treatment of water hyacinth with Phanerochaete chrysosporium and Phanerochaete chrysosporium + pyrogallol red showed 243.82 and 314.07l/kgdm of gas production respectively i.e. about 143 % and 213.2 % more than the gas obtained from pure water hyacinth. Accordingly increase in manurial value with respect to NPK was also observed.

Key words: Anaerobic digestion, biogas, fungi.
