Maximum amounts of P-released, time of growth, pH and colony forming units (CFU mL⁻¹) in NBRIP-BPB media with Ca₃(PO₄)₂ by native bacteria (64S1, 42P4, 60I1 and 53F).

Strain	P released (μg mL−1)†,#	Time of growth (h)‡	pH§,#	CFU mL−1††
Enterobacter 64S1	437.98 ± 44.07a	24	3.93 ± 0.03c	3 × 108
Pseudomonas 42P4	407.54 ± 17.34a	24	3.89 ± 0.03c	8 × 108
Cellulosimicrobium 60I1	173.08 ± 7.72c	168	4.52 ± 0.04a	4 × 107

^†Maximum levels of soluble phosphorus released.

^‡Time of growth (h) in which maximum levels of soluble P were released.

^§Lowest culture pH reached during incubation time.

^††Colony-forming units (CFU mL⁻¹) at time of maximum levels of soluble P released by each bacterium.

^#Values are mean ± SE of six independent replicates (n = 6). Different letters indicate differences among isolates according to LSD Fisher test (P < 0.05).
