Growth-promoting activity of Tomitella biformata recombinant Rpf expressed in Rhodococcus erythropolis M1218 on T. biformata cultures. (A) Reduction in the lag phase with increases in the rRpf concentration and (B) growth rate (d⁻¹). A logarithmic phase culture of T. biformata cells was washed, diluted, and added to mMMF medium containing rRpf protein concentrations of 100 nM, 10 nM, 1 nM, 0.1 nM, and 0 nM control. The initial cell concentration of T. biformata grown in mMMF medium was 3.10×10² CFU mL⁻¹. (n=3 per Rpf treatment, error bars represent SE)
