Q
3 PEOPLE IN THE EXPERIMENTS ON THE THEORY OF SG
A
- FRANCESCO REDI
-JOHN NEEDHAM
-LAZZARO SPALLANZANI
2
Q
- Italian Physician
- He refuted the idea that maggots spontaneously generate on meat left out in the open air
A
FRANCESCO REDI
3
Q
- English (Scottish) clergyman
- He argued that microbes arose spontaneously in broth from a “life force”
A
JOHN NEEDHAM
4
Q
- Italian priest, bilogist, and psychologist
- Has experiments with broth aimed to disprove those of Needham
- He hypothesized that microbes from the air and boiling will kill them
A
LAZZARO SPALLANZANI
5
Q
NEEDHAM’S BROTH PROCESS
A
- Boiled broth for 1 minute
- Sealed with loose cork
- Bacteria still grew
- Therefore, spontaneous generation must be true
6
Q
HOW DID PASTEUR DISPROVED THE THEORY OF SG
A
- Pasteur predicted that microorganisms in putrefying materials were descendants of cells that entered from the air or cells that had been initially present on the decaying materials
- He reasoned that if food were treated in such a way as to destroy all living organisms present–that is, if it were rendered sterile–and if it were kept sterile, it would not putrefy

Q
4 PEOPLE BEHIND MAJOR DISCOVERIES IN MICROBIOLOGY
A
-LOUIS PASTEUR
-ROBERT KOCH
-MARTINUS BEIJERINK
-SERGEI WINOGRADSKY
8
Q
His principles were quickly adapted for the preservation of milk and many other foods by heat treatment, which we now call
A
-PASTEURIZATION
9
Q
3 VACCINES THAT PASTUER DEVELOPED
A
- ANTHRAX
- FOWL CHOLERA
- RABIES
10
Q
- Metabolic process by which organic molecules (normally glucose) are converted into acids gases, or alcohol in the absence of oxygen
A
FERMENTATION
11
Q
- Process of killing or removing all forms of life, especially microorganisms, associated with a given object or present in a given area
A
STERILIZATION
12
Q
free of all living organisms (cells) and viruses
A
STERILE
13
Q
- Heating of milk for a short time to a temperature that will destroy undesirable microorganisms without changing the composition and food value of the material itself
A
PASTEURIZATION
14
Q
- Causative agent of a disease (bacterium, toxin, virus, or other microbes) so modified as to be incapable of producing the disease yet at the same time so little changed that it is able, when introduced into the body to elicit the production of specific antibodies against the disease
A
VACCINE
15
Q
- He provided direct experimental support to the germ theory of disease:
> Microbes were the cause of infectious disease
A
