question
purple sulfur bacteria
answer
oxidize hydrogen sulfide to elemental sulfur and sulfuric acid; CO2 is the only source of C
question
green sulfur bacteria
answer
use sulfide for oxidation
question
purple nonsulfur bacteria
answer
use hydrogen. Ex: Rhodospirillum (metabolize nitrogen; facultative aanerobes)
question
green nonsulfur bacteria
answer
use substances other than sulfides for oxidation
question
