        *A note on stimulation of biogas production from cattle dung
        by addition of charcoal*

        *Sushil Kumar, M.C. Jain, P.K. Chhonkar*



        *Abstract*

        Various forms of carbon were screened for their ability to
        stimulate biogas production in batch fermenters and the
        commercial charcoal which was found to be most efficient was
        tried in a semi-continuous anaerobic digester. The addition of
        5% commercial charcoal to cow dung on a dry weight basis
        resulted in augmentation of gas production by 17% and 34·7% in
        batch and semi-continuous fermenters, respectively. Analysis
        of the microbial profile of the fermenters showed that
        fermenters with charcoal had a higher number of both total
        anaerobic bacteria and cellulolytics. The decomposition of
        Volatile Solids increased from 30% to 34% and COD reduction
        from 55% to 69% on addition of charcoal to the semi-continuous
        digester. The Volatile Fatty Acid concentrations were similar
        and within the acceptable limits. Locally-produced wood
        charcoal was as good as the commercial charcoal in batch
        digestions, but other forms of carbon were not as efficient.
