^a-cMeans in the same row with no common superscripts are significantly different at a probability level of P < 0.05.

Abbreviation: IPF: inorganic-P-free.

¹Displayed P values < 0.05 without superscripts next to associated means indicates a statistically significant ANOVA result but non-significance from means separation using Tukey's honest significant difference test, at P < 0.05.
