photsynthesis.: --
9. 1. Physical State
2. Chemical Composition
3. Functional Type: 3 ways media can be classified
10. exact chemical composition is known. It is under the chemical composition
of the 3 ways media can be classified: defined media (synthetic)
11. contain some ingredients of unknown composition and/or concentration.
It is under the chemical composition of the 3 ways how media can be classi-
fied: complex media
12. Grows many types or a broad spectrum of microbes. As a rule, they are of
the complex variety and contain a mixture of nutrients that could support the
growth of a variety of microbial life. It is under the functional type of 3 ways
how media can be classified: general purpose media
13. contains complex organic substances such as blood, serum, hemoglobin,
or special growth factors required by fastidious microbes. An enriched medi-
um contains complex organic substances such as blood, serum, hemoglobin,
or special growth factors (specific vitamins, amino acids) that certain species

require in order to grow. It is under the functional type of 3 ways how media
can be classified: enriched media
14. Suppress unwanted microbes and encourage desired microbes. encour-
ages a select microorganism to grow by containing one or more agents that
inhibit the growth of other microorganisms. It is under the functional type of
3 ways how media can be classified: selective media
15. allow multiple types of microorganisms to grow. Allow multiple types of
microorganisms to grow, but display visible differences between colonies. It
is under the functional type of 3 ways how media can be classified: differential
media
16. 1. selective
2. complex
3. differential: 3 types of media
17. Contrast degree to which an object stands out from it's surroundings.
Contrast is measured by a quality called the refractive index. Refractive index
refers to the degree of bending that light undergoes as it passes from one
medium (such as water or glass) to another medium, such as some bacterial
cells.: contrast
18. Capacity of an optical system to distinguish or separate two adjacent ob-
jects or points from one another. The human eye can resolve two small objects
as separate points just as long as the two objects are 0.1 - 0.2 millimeters
apart.: resolution
19. A French chemist, this man discovered that heat could kill bacteria that
otherwise spoiled liquids including milk, wine, and beer.: Louis Pasteur
20. Pasteur discovered through experiment that life doesn't create out of
nothing. He disproved the theory of spontaneous generation through his
swan-neck experiment.: Louis Pasteur #2
21. Louis Pasteur: Father of Microbiology
22. laid down the conditions, known as Koch's postulates, which must be
satisfied before it can be accepted that particular bacteria cause particular
diseases: Robert Koch
23. "Father of Epidemiology", studied the London Cholera epidemics of 1848
& 1854, suspected it was from the water, as most cases were found close to
the Broad Street pump.
Found the causative agent of a cholera outbreak in England in 1854. He drew
and created a map to conclude where the source of an outbreak of a disease.
This is kind of like epidimielogy.: John Snow
