TABLE 1.

Growth rates of P. aeruginosa with different sulfur sources^a (h⁻¹)

Sulfur source	Growth ratea (h−1) (mean ± SD) of:
	P. aeruginosa E601	P. aeruginosa PA01
Cyclamate	0.105 ± 0.008	0.135 ± 0.022
Sulfate	0.100 ± 0.004	0.313 ± 0.010
Human mucin	0.0047 ± 0.0001	NG
Pig mucin	NG	NG
Cyclamate + human mucin	0.108 ± 0.005	0.141 ± 0.002

^aMaximum growth rates were determined in the exponential phase of growth in a vigorously shaken microplate by measuring the A₆₀₀ every 10 min. Values were determined in three independent experiments, with eightfold replication in each experiment. NG, no growth.
