Nickel added in concentrations as low as 10..mu..M significantly increased biogas production in a laboratory poultry waste digester utilizing excreta from laying hens as the organic energy source. It was shown that the initial rate of biogas production increased as early as 4 h after the addition of nickel to the laboratory cultures. Analysis of the excreta for nickel content prior to addition of exogenous NiCl/sub 2/ showed appreciable amounts of nickel present. The data indicate that nickel naturally present in layer excreta is suboptimal or unavailable to the bacteria for biogas production purposes.
