Microbiology
Six Kingdoms of Life:
Eubacteria.
Archaebacteria
Protista
Plantae

Animalia
Three Domains:
Bacteria
Bacteria
Unicellular, prokaryotic organism (simple, no organelles)
Asexual reproduction
Ubiquitous (found everywhere) dependent on the environmental conditions
Classification of Bacteria
Appearance
Macroscopic
Each colony is derived from one single bacteria
It takes 20-30 minutes for bacteria to divide in ideal conditions
Colony Morphology - Bacteria always grow in the same shape
Colony Shape
Colony Edge/margins
colony Elevation
Another classification method based on appearance is the bacteria’s color, smell, or appearance, such as whether it looks mucoid or dry.
