Abstract :

The main objective of the present paper is to find the effect of elemental Selenium on progressive biogas production. Laboratory scale digesters of 2.5 l capacity were used and fed with Holy Basil (Ocimum sanctum) as the substrate, cow dung as the inoculum and digested in a batch reactor for a retention period of 45 days at mesophilic temperature. During the course of experiment, pH, temperature and biogas production were monitored daily. Solids, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Lignin and Cellulose were analyzed at a regular interval of 5 days using standard methods. The yield of biogas generated was increased 1.38 folds from 0.453dm3/kg to 0.613 dm3/ kg in digester with Selenium concentration of 2mM when compared with control digester. The overall performance of the digester was increased with the addition of Selenium.
