enriched media—ANSWER-media that grows fastidious organisms and contain nutrients for
a particular microbe
True—ANSWER-True or false: BAP is an enriched, non-selective yet differential media. The
red blood cells in the media promote the growth of fastidious microorganisms, such as
various strains of Streptococcus.
BAP—ANSWER-____ is a differential media used to detect hemolytic activity.
False—ANSWER-True or false: growth media is best suited for distinguishing between two
similar species of bacteria
True—ANSWER-True or False: differential media is best suited for distinguishing between
two similar species of bacteria
D. Differential media—ANSWER-A researcher is asked to determine which of two vials
contains E.coli and which contains salmonella. Knowing both are gram-negative while only
one of them is capable of fermenting lactose, which type of media would be best suited?
A. Selective and Differential Media
, B. Selective media
C. Growth Media
D. Differential Media
Selective media—ANSWER-What type of media is best used to eliminate certain bacteria
from within a mixed culture?
A. Selective media—ANSWER-A researcher is asked to determine if a sample contains
Neisseria meningtides. Knowing Neisseria meningtides is slow growing and other foreign
microbes may also be present in the culture, which type of media would be best suited?
A. Selective Media
B. Selective and Differential media
C. Differential Media
D. Growth Media
A fastidious microbe is an organism with complex growth requirements such that if absent it
will not grow. Enriched medias thus contain these specific and essential nutrients required
for the growth of a particular subset of microorganisms.—ANSWER-What are the
requirements of a fastidious microbe?
True—ANSWER-True or Fals: LB agar is classified as a non-selective, non-differential media
Growth media in a liquid form is often referred to as a nutrient broth. As the name implies
its composition consists primarily of essential 'ingredients' such as a rich source of sugars,
amino acids, and vitamins. Together, a nutrient broth provides the microbe with a source of
