Abstract
The resistance of Sporolactobacillus to different concentrations of potassium sorbate and sodium nitrite in autoclaved glucose yeast-extract peptone broth, pH 6.0, was determined. The minimum inhibitory concentration of potassium sorbate that completely inhibited outgrowth of endospores and vegetative growth of Sporolactobacillus inulinus ATCC 15538 was 4000 μg/ml and 5000 μg/ml, respectively. For twelve isolates of Sporolactobacillus the average minimum inhibitory concentrations of potassium sorbate that completely inhibited outgrowth of endospores and vegetative growth were 5000 μg/ml and 7000 μg/ml, respectively. Resistance of endospores of Sporolactobacillus to different sodium nitrite concentrations was high. Outgrowth of spores took place at sodium nitrite concentrations as high as 2000 μg/ml.
