WT1.4 ± 0.1
4k2.4 ± 0.2
4k::PSPE1.2 ± 0.1
4k::GLPE1.1 ± 0.1
4k::RDHA1.1 ± 0.1

  • a The doubling time was derived from the length of the exponential growth phase. The data are averages with standard deviations from three cultures. The P values (by t test) for the 4k strain versus others were all <0.05.
