What is microbiology
the study of living things too small to be seen with the naked eye
aka microorganisms/microbes
-
Groups of microorganisms
bacteria, protist ,fungi,helminths &viruses
-
what is a virus
a non living ,noncellular, parasitic protein-coated genetic element that infect all living things, including other microorganisms
-
what is a prokaryote?
organisms without a true nucleus
-
eukaryotes
organisms with a true nucleus
-
bioremediation
introducing microbes to the environment
-
which cell is smaller prokaryote or eukaryote?
prokaryotes are 10x smaller
-
earliest record of microbes
robert hooke 1660
-
created the single lens microscope?
antonie van leeuwenhoek
-
whos known as the father of biology and protozoology
antoni van leeuwenhoek
-
theory of biogenesis
studied and confirmed by pasteur in the mid late 1800
-
s shaped flask
designed by pasteur to confirm theory of biogensis
-
Germ thoery
discovered by louis pasteur who made the correlation of germs and dieases
-
who discovered fermentation and pasteurization
pasteur showed that microbes are responsible for fermentation
-
fermentation
the conversation of sugar to alchol to make beer and wine
-
pasteurization
spoilage bacteria can be killed by heat high heat for a short time
-
joseph lister
used a chemical disinectant to prevent surgical would infections he introduced aseptic techniques
-
robert koch
created koch postulates which was used to prove that a specific microbe causes a specific diease
-
microbial nomenclature
naming organismins
-
taxonomy
classifying living things
-
levels of classification
3 domains 6 kingdoms
-
identificaton
discovering and recording the traits of organisms so they can be named and classified
-
3 domains
archea eubacteria, eukarya
-
6 kingdoms
achaebacteria, bacteria, protists, fungi, plants, animals
-
classification(king phillip came over for good spagetti
kpcofgs
kingdom,phylum, class, order, family, genus , species
-
archaebacteria& bacteria are?
prokaryotes
-
protist, fungi, plants, animals are
eukaryotes
-
binomial system of nomenclature
- –The generic (genus) name followed by the
- species name
- –Generic part is capitalized, species is
- lowercase
- –Both are italicized or underlined if
- italics aren’t available
- –Staphylococcus aureus,
- Homo sapien, T. rex.
-
Phylogeny
- •the
- degree of relatedness between groups of living things based on ancestry/evolution.
-
Evolution
- •hereditary
- information in living things changes gradually through time; these changes
- result in structural and functional changes through many generations
