Fig. 5

Effects of organic substances on respiratory rate in C. merolae cells at different flat-plate culture times. a Glucose, glycerol, pyruvate, and l-lactic acid were added to culture at 0 (blue), 1 (red), 3 (light green), and 6 h (purple) in the flat-plate culture, and respiratory rate was measured. Results at 0 h are adopted from the results of Fig. 4 in each substance. Each value is an average ± standard deviation of triplicates. b From the results of (a), maximum values of respiratory rates at different culture times are plotted. Vertical scale is indicated as logarithmic scale
