Growth and energetics of bacteria

Classification of Bacteria by Nutritional Requirement:

Energy Source:	Carbon Source:	Name:	Example:
Light	Inorganic	Photoautotroph	Most Photosynthetics: Chromatium (anaerobic); Cyanobacteria (aerobic)
Light	Organic	Photoheterotroph	Purple and Green Photosynthetics; Rhodospirillum
Inorganic	Inorganic	Chemolithotrophic autotroph (Chemoautotroph)	Nitrobacter
Inorganic	Organic	Chemolithotrophic heterotroph (mixotroph)	Desulphovibrio
Organic	Inorganic	Chemoorganotrophic autotroph	Pseudomonas oxalaticus
Organic	Organic	Chemo (heterotroph)	Escherichia coli
