Values are means±STD (n=125).
Small letters mean within a row with different superscripts in are significantly different at the p<0.05 level.
* Values between sample are significantly different at the p<0.05 level.
LPD, lag phase duration (h); µmax, maximum specific growth rate (Log CFU/mL/h); r2, coefficient of determination.
