Table 1. Growth parameters of S. oneidensis cultivated in different media under aerobic conditions.

Medium	Doubling timea	Relative yieldb
MM3	114 +/− 6	1.00
MM3C−	237 +/− 12	0.34
MM3I−	137 +/− 7	0.50
LB	54 +/− 1	11.36

^aExpressed in min (mean +/− standard deviation).

^bRelative yield is defined as the highest optical density at 600 nm in early stationary phase in the different cultures relative to that of the wild-type strain culture in MM3 medium. The standard deviation is less than 3%.

Data were obtained from at least three separated experiments.
