	AIA production μg/mg protein
Strain	16 ha	24 hb	36 hc	40 hd
A. brasilense Sp7	6.38* (36.4 μM)	29.1* (166.1 μM)	37.4* (213.4 μM)	38.79* (221.4 μM)
A. brasilense 2116	3.84* (21.9 μM)	23.35* (133.2 μM)	30.66* (175 μM)	35.62* (203.3 μM)
A. brasilense 2112	ND	2.37* (13.5 μM)	4.05* (23.1 μM)	5.2* (26.6 μM)

* IAA production was determined at

^a exponential phase (OD₆₀₀ = 1.04 ± 0.01)

^b initial stationary phase, (OD₆₀₀ = 1.29 ± 0.01)

^C stationary phase, (OD₆₀₀ = 1.34 ± 0.02); and

^d late stationary phase, (OD₆₀₀ = 1.34 ± 0.01). The results are from three independent experiments. ND, not determined.
