Heat-map of the Pearson correlations of beta-<i>proteobacteria</i> (<i>Bet</i>), alpha-<i>proteobacteria</i> (<i>Alph</i>), Cytophaga-Flavobacteria (<i>CF</i>), Eubacteria excluding <i>Alph</i>, <i>Bet</i> and <i>CF</i> (<i>EUBI-III<sub>(undef)</sub></i>) and not-defined DAPI positive cells (ND) to physico-chemical variables.

<p>Asterisk indicate the p-value (*: p<0.05; **: p<0.01; ***: p<0.001) of correlations between paired samples.</p>
