aIn Trial-1:P value for the difference among mean values was <0.005. The mean value of a strain designated by a dagger (†) is significantly different from the mean value of a strain designated by a double dagger (‡) but is not significantly different between strains designated by the same symbol.

In Trial-2: The observed significance level among mean values was < 0.1 <P < 0.9.
