However, for EPS production, the model did not reach statistical significance ( p -value = 0.087).
However, for EPS production, the model did not reach statistical significance ( p -value = 0.087).
EPS from cultures treated with 0.03 g·L −1 sodium metasilicate did not show a clear trend, with values varying across the pH range; for example, at pH 2.0, the zeta potential was −13.04 ± 0.65 mV, at pH 4.0, the value was −5.19 ± 0.66 mV, and at pH 8.0, the value was −8.63 ± 0.58 mV.
