A primary difference between cyanobacteria and purple and green phototrophic bacteria is
electron donor for CO2 reduction
Which bacteria are responsible for more infections and more different kinds of infections
Streptococcus
The nonsulfur (photoheterothoph) use organic compound as
electron donors to reduce CO2
Streptomyces differs from Actinomyces because Streptomyces
is a strict aerobe
Salmonella, Shigella, Yersinia and Serratia are all
gram negative facultatively anaerobic rods

Bacillales
Caulobacter are different from most bacteria because
They have stalks
Which bacterium is motile and does not have flagella
Spirochetes
Mycoplasmas differ from other bacteria because
They as well less or lack a cell wall
