A. Antibiotics, such as gentamicin, are used in media to prevent growth of susceptible microbes. Is gentamicin media a selective, differential or enrichment media? B. Sorbitol is a sugar alcohol that all Escherichia bacteria can normally ferment into an acidic waste compound. This acidic end product is detected by including a pH indicator in the agar and noticing a color change. The strain of Escherichia that is a common food pathogen, E. coli O157:H7, however can not ferment sorbitol. It will grow similar to other E. coli, but not change the agar color. Is sorbitol in nutrient agar a selective, differential or enrichment media?
