Fig 4. Growth yields of the parent strains and the complemented strains.

Fig 4

(A) Complementation by S. mutans EriC1b, S. anginosus EriC1, or S. sanguinis CrcB1/CrcB2 in the S. mutans EriC1a/EriC1b double mutant. (B) Complementation by S. anginosus EriC1 or S. mutans EriC1b in the S. anginosus EriC1 mutant. (C) Complementation by S. sanguinis CrcB1/CrcB2 or S. mutans EriC1b in the S. sanguinis CrcB1/CrcB2 double mutant. The y-axis represents the OD550 after incubation for 16 h. The data represent the mean standard deviations of three independent experiments. *, significant differences against the OD550 value of the wild-type strain within the same NaF concentration; #, significant differences against the OD550 value of the strain complemented by its own fluoride-resistance gene(s) within the same NaF concentration.
