Metabolic-network-driven analysis of bacterial ecological strategies

Table 2 Typical duplication time of bacterial organisms according to their mode of respiration

	Number of species*	Mean duplication time	Median duplication time	Mean network size
Aerobic bacteria	40	13	3	412
Anaerobic bacteria	18	5.3	1.6	318
Facultative bacteria	41	1.7	0.8	380

Oxygen-dependence annotations were taken from [34]. *Species in this analysis are those for which duplication times are available, the metabolic network was reconstructed (Materials and methods), and their oxygen-dependence group is one of the groups in the table (bacteria species whose oxygen-dependence annotation is 'unknown' or 'microaerophylic' are not shown here).
