Growth of Pseudomonas strains on various aromatic compounds^a

Substrate	Mean doubling time (min) ± SD of strain:
	PRS2000	4NT	TW3
Benzoate	77 ± 11	54 ± 2	113 ± 8
4-Hydroxybenzoate	123 ± 24	118 ± 14	92 ± 9
4-Nitrobenzoate	−	180 ± 36	124 ± 13
3-Nitrobenzoate	−	−	−
2-Nitrobenzoate	−	−	−
4-Aminobenzoate	−	−b	−c
3-Aminobenzoate	−	−	−
2-Aminobenzoate	−	−	−
4-Nitrotoluene	−	179 ± 23	296 ± 16

^aGrowth was assessed by auxanography as described in Materials and Methods. Positive growth was verified in liquid culture (MSB containing 5 mM benzoate or 4- hydroxybenzoate or saturating 4-nitrobenzoate or 4-nitrotoluene at 30°C with shaking at 250 rpm); −, no growth.
