Assessment of antibiotic resistance from long-term bacterial exposure to antibiotics commonly used in fuel ethanol production

The objective of this study was to evaluate the ability of two bacterial strains [Lactobacillus plantarum (18A) and Lactobacillus paracasei(18C)] isolated from the fuel ethanol industry to acquire bacterial resistance during long-term (≥ 14 days) exposure to sublethal concentrations of penicillin G and virginiamycin. The results indicate that antibiotic resistance in two common Lactobacillus strains does not develop from sublethal exposure to virginiamycin after 69 days of exposure, but resistance can be developed with sublethal exposure to penicillin G.
