|
what is the difference between selective media and differential media?
|
selective media only allows specefic species to grow while differential media will distinguish between species usually by a dye or some other indicator
|
|
|
distinguish between the two types of liquid media.
|
complex media have parameters for many bacs while defined media are specefic to one species with its specefic nutritional needs
|
|
|
all bacteria of clinical significance are considered what?
|
chemoheterotrophs
|
|
|
facultative bacs can...
|
use fermentation when there is no O2 but will use respiration if O2 is present
|
|
|
what are the oxidative and reductive phases of glucose metabolism?
|
glycolysis is oxidative while fermentation and further metabolism of pyruvate to various end products is reductive.
|
|
|
what is the importance of the pentose monophosphate glycolytic pathway?
|
it provides NADPH and pentoses for biosynth and it is a pathway for the utilization of pentoses as C and energy sources
|
|
|
the ED glycolytic pathway is different than the traditional glycolytic pathway how? what species uses it?
|
less energy efficient and used in pseudomonads
|
|
|
the chemical purpose of fermentation is what? how is it helpful to us?
|
it recycles NADH back to NAD. thespecefic fermented product made helps identify the species
