chapter 1 Microbial world and you

Microbes in our lives: too small to see with the naked eye bacteria, arches, fungi, protozoa, microscopic algae
who created the binomial (two names; genus and species) Carolus Linneasus 1735
Bacillus rod shaped
coccus spherical ex: ball
spirella spiral shaped ex: a cork
vibrio comma shaped
prokaryote "pre nucleus"
morphology shape
Archaea prokaryotic, cell walls lack peptidoglycan, live in extreme environments: methanogens, extreme halophiles (high salt), extreme thermophiles (heat)
Bacteria cell wall: carbohydrate and protein complex, reproduce binary fission (spilt)
Fungi eukaryotes (contain membrane bound organelles) can be large and multicellular (mushrooms) can be unicellular- yeasts. Oval shaped, larger than bacteria, molds, can reproduce asexually and sexually.
yeasts Saccharomyces cervisaiae
Protozoa unicellular eukaryotes: move by several means
