  • a  Shown are ratios of the OD590 in a carbon-containing well to the OD590 of a no-carbon-added control well after 48 h incubation at 37°C. A ratio >2 was considered a positive result. Each strain was tested twice, and the data shown are for both trials. Ratios of <2 are not shown. All ratios for E. gallinarum were <2.
