- The optimum growth pH for a microorganism is usually: 4,5,7 or 8Below 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 CIs 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

SS agar plate - results of kitchen sink drain and kitchen dish cloth (plate below) Salmonella-Shigella (SS) agar: Salmonella-Shigella agar (SS agar) is a selective and differential medium utilized for the selection and characterization pathogenic enteric bacteria. SS agar contains lactose, bile salts, ferric citrate, and neutral red. Kitchen The bile salts select for Gram-negative bacteria, while inhibiting Gram-positive bacteria. sink drain The other components differentiate among Gram-negative bacteria. Coliform bacteria such as E. coli will ferment the lactose in the media, resulting in bacterial growth with a pink color. (They do not produce any hydrogen sulfide.) Members of the genus Salmonella will not ferment lactose, but do product hydrogen sulfide…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.
