**5.4** *E. coli* **on Mueller Hinton agar**

Starch is added to absorb any toxic metabolites produced and starch hydrolysis yields dextrose, which serves as a source of energy. The use of a suitable medium for testing the susceptibility of microorganisms to sulfonamides and trimethoprim [28] is shown in **Figure 6**.

**Figure 5.** *Colonies of* E. coli *on MacConkey agar plate are pink to dark pink, [27].*
