Notes:

Liquid medium with various carbon sources including 1% pectin, 0.5% pectin + 0.5% CMC or 1% CMC were used in the experiment, grown at 25 °C with shaking at 100 rpm.

r = Correlation coefficient.

Correlation was analyzed using the Pearson correlation coefficient in SPSS 20.0 software.

^*Correlation significant at the p < 0.05 level.

^**Correlation significant at the p < 0.01 level.
