Abstract:

The effect of pH and organic matter (total organic carbon, TOC) of effluents originating from fishing industries located in Talcahuano, Chile, on the ability to colonize different trophic group methanogenic bacteria (MB) over clay and polyethylene supports was evaluated. Both support materials enhanced all types of methanogenic bacterial growth compared to systems without support. The highest adherence was obtained at pH 8. At 8000 mg/l TOC, this had a significant effect on the growth rate of hydrogenotropic and methylaminotrophic methanogens on polyethylene and clay, respectively. Copyright 1999 Academic Press
