Swimming motility of P. chlororaphis PCL1606 and its derivatives after 24 h of incubation at 25°C. (A) Swimming haloes of P. chlororaphis PCL1606 and its derivative strains. HPR production is indicated. +++ = HPR production level of the wild-type strain P. chlororaphis PCL1606; ++ = ½ of HPR production compared to the wild-type; + = ¼ of HPR production compared to the wild-type; – = no production. Scale bar indicates 1 cm. (B) Average swimming halo area (cm2) and standard deviations of five independent experiments are presented. Different letters indicate statistically significant differences (P > 0.05).
