To prepare media, add 20 g of phenol red dextrose broth to a liter of distilled or de-ionized water. The media will not be sterile until autoclaved prior to use.

Used to determine if bacteria produce extracellular enzymes to catalyze the hydrolysis of starch. Organisms that produce a starch hydrolyzing enzyme will display a clear zone around the area of growth while other areas of the agar containing starch will turn blue-black.

A medium helpful in differentiation of the enterobacteriaceae. Simmons citrate agar test for organisms that are able to utilize citrate as a carbon source.

To assist in the differentiation of enteric organisms the medium provides three tests - indole production, production of hydrogen sulfide by organisms that can reduce sulfur, and motility.

For recombinant strains of Escherichia coli that are Ampicillin resistant.
