ABSTRACT
The effect of ethanol and methanol on growth of several ruminal bacterial strains was examined. Ethanol concentrations as low as 0.2% had a significant, but moderate, inhibitory effect on lag time or growth over time and 3.3% ethanol significantly inhibited maximum optical density obtained by both Selenomonas ruminantium and Butyrivibrio fibrisolvens. Little growth of either strain occurred at 10% ethanol concentrations. Methanol concentrations below 0.5% had little effect on either growth or maximum optical density of Selenomonas ruminantium whereas methanol concentrations below 3.3% had little effect on growth or maximum optical density of Butyrivibrio fibrisolvens. Higher methanol concentrations increasingly inhibited growth of both strains and no growth occurred at a 10% methanol concentration. Concentrations of ethanol or methanol used to add hydrophobic compounds to culture media should be kept below 1%.
