Solubilized P and biomass produced by <i>Aspergillus niger</i> FS1 mutants compared to the wild type.

The experiments were carried out in liquid NBRIP medium supplemented with F− at 50 mg L−1 (NBRIP-F) or NBRIP with 3 g L−1 of Araxá RP as the only P source. Flasks were incubated for 60 h at 32°C and 160 rpm. aThe percent increase or decrease of solubilized P of the mutants was calculated based on the solubilized P by the WT in the media NBRIP-F and NBRIP with RP, respectively 346 and 61 mg L−1. P (%) = (mMUT–mWT)/mWT×100; mMUT: mean solubilized P for the mutant; mWT: mean solubilized P for the wild type. Means followed by the same letter are not significantly different according to the Scott Knott test (P<0.05).
