Table 1.

The highest levels of soluble P released by A. niger and Acinetobacter sp. detected after five-days incubation. TCP and FAp were added to the PVK medium as a P source.

Phosphorus sources	A. niger		Acinetobacter sp.
	pH	Soluble P concentration (mg L−1)	pH	Soluble P concentration (mg L−1)
TCP	3.5 ± 0.1a ab	770.5 ± 21.7 a	4.2 ± 0.0 b	402.3 ± 11.0 a
FAp	3.1 ± 0.3 a	4.2 ± 0.2 b	6.6 ± 0.0 a	0.9 ± 0.1 b

^aData were listed as mean ± S.E.

^bValues followed by different letter (a–b) in the column are significantly different according to a Duncan’s Multiple Range Test at P < 0.05.
