Is the mannitol salt agar (MSA) a complex or defined medium? Explain based on Composition. What kind of media based on what kind of microorganisms it allows to grow
MacConkey agar inhibits the growth of Gram-positive bacteria while encouraging the growth of Gram-negative bacteria. It also can determine if some bacteria use lactose. Define what type(s) of media MacConkey agar is, using as many terms in the answer list as are applicable.
Below is an image of 3 different bacteria, letter labeld, growing on MacConkey Agar. Note that bacteria such as E. coli use mixed acid fermentation, with very high acid production which will cause a colored precipitation around colonies on MacConkey agar. MacConkey Agar C
Which of the following is the proper technique for inoculating an agar slant with a broth culture? A. Stab the butt of the media with the wire loop. B. Stab the surface of the agar media with the wire loop beginning at the base of the tube moving toward the mouth as you withdraw the loop. C. Gently move the wire loop back and forth across the surface of the agar beginning at the mouth of the tube moving down toward the base of the slant. D. Gently move the wire loop back and forth across the surface of the agar beginning at the base of the slant as you withdraw it from the tube.
Describe how each of the following would appear when grown on EMB agar: a. Escherichia coli b. Pseudomonas aeruginos
EMB agar inhibits the growth of Gram-positive bacteria while encouraging the growth of Gram-negative bacteria. It also can determine if some bacteria use lactose. It is particularly effective at determining if E. coli is present in a specimen. Define what type(s) of media EMB agar is, using as many terms in the answer list as are applicable.
