what is microbiology?

Study of microbes

2

what are microbes?

living things too small to be seen with naked eye

3

what are some examples of microbes?

Bacteria
Protozoa
Microscopic algae
viruses
fungi

4

What are some uses of microbes?

aquatic microbes form basis of food chain
soil microbes break down waste
photosynthetic microbes generate O2

what are some other uses of microbes?

in human digestive tract aid in the digestion and help produce vitamin B and K
used to produce acetone, alcohol, antibiotics

6

what are some more uses of microbes?

used to produce vinegar, sauerkraut, pickles, cheese, bread, and yogurt
bio remediation (oil spills)
enzymes (detergents)

7

what is bacteriology?

the study of bacteria

8

what is mycology?

The study of fungi

9

what is virology?

the study of virus

10

what is immunology?

the study of the immune system

11

What is taxonomy?

classifying organisms

21

Why do we classify organism?

10-100 million species on Earth
identify similaries and differences
provide a tool for evolutionary history

what is the hierarchy of organisms?

domain
kingdom
phylum
class
order
family
genus
species

establish by Carl Woese
based on rRNA data

25

what are the three main domains?

Eukarya
Bacteria
Archaea
