Bt showed a wide range of metabolic potential and was able to grow on every carbon source presented except for ornithine. Each carbon source in LSM is used both for the production of biomass as well as the primary electron donor to generate energy via aerobic respiration. The electron equivalents are then multiplied by the total number of molecules of the carbon source in the media. This yields the total electron equivalents for each carbon source per liter of media. If a carbon source is consumed, then i=1, if it is not able to be consumed, then i=0.
