Fig. 2From: An insight into the role of the organic acids produced by Enterobacter sp. strain 15S in solubilizing tricalcium phosphate: in situ study on cucumberMechanisms of P solubilization by Enterobacter 15S grown during 7 days in NBRIP liquid medium supplemented with Ca3(PO4)2 at 0.1% P (w/v). A Phosphate solubilization, B pH changes, C organic acid production, and D Pearson correlation matrix between solubilized P, pH values and organic acids. Color gradients and numbers denote Pearson’s correlation coefficients. Asterisks denote significance (*** P < 0.001)Back to article page
