	Doubling Time (h)*	Radial Growth Rate (mm h−1)	Doubling Time (h)*	Radial Growth Rate (mm h−1)
A83	4.04 ± 0.98	0.12 ± 0.02	3.22 ± 0.41	0.29 ± 0.03
B7	3.86 ± 0.54	0.02 ± 0.005*	3.53 ± 0.56	0.30 ± 0.03
B7R	4.81 ± 1.11	0.11 ± 0.01	3.47 ± 0.40	0.32 ± 0.04

C6309R	4.51 ± 1.30	0.12 ± 0.02	3.99 ± 0.32	0.28 ± 0.03

Doubling times were measured in liquid media at pH 7.3 and 6.0. Radial growth rates were tested on solid medium at pH 7.3 and 5.6. Results are expressed as the mean ± SD.
