What do soy sauce, a Begonia and a dented can have in common?

The Good, the Bad and the Essential Bacteria and People The Good, the Bad and the Essential

Essential Bacteria

Essential Bacteria Nitrogen fixing bacteria  Atmospheric N₂ into NH₄

Essential Bacteria Gut flora  helps animals digest food

Essential Bacteria Cyanobacteria  blue-green algae, create oxygen with photosynthesis

Useful Bacteria

Useful Bacteria Food  yogurt, cheese, soy sauce, pickles

Useful Bacteria Insulin production  faster and more effective

Harmful bacteria

Harmful Bacteria Pathogens!! Bubonic Plague/ Black Death  Killed half the population of Britain in the 14th century

Sent out in mail in 2001, killed 5 Harmful Bacteria Anthrax  Sent out in mail in 2001, killed 5

Harmful Bacteria Botulism  Anaerobic bacteria creates toxins
