Abstract

The fate of pathogens in anaerobic digesters has been studied in a laboratory model system in which glucose-nutrient broth cultures of genetically-defined strains ofEscherichia coli received additions of fatty acids at concentrations similar to those attained during anaerobic treatment of farm wastes. Marked concentration-dependent inhibition of growth was observed for both antibiotic resistant and sensitive strains, and the effects increased with increasing chain lengths up to C8. Survival of enteric organisms during anaerobic digestion may be limited by fatty acid toxicity.
