Growth analysis of wild type Xcc8004, EPS deficient mutants (B5 and B12), ndvB and ndvB (pHMJ) grown in PS medium (A); PS medium containing 50 µm extracellularion chelator, diethylenetriaminepentaacetic acid (DETAPAC) (B); or supplemented with either with (C) secreted glucan (0.5 mg/ml); (D) xanthan (0.5 mg/ml); (E) FeSO4 (40µM); and (F) MnCl2 (40µM). Data shown are mean ± SD (n=3). From here onward, until not mentioned, the 'n' indicates three biological replicates.
