BIO 171 Module 4 Exam (Essential Microbiology) Questions and Answers 2023, Score 100%. Portage Learning. Differential media is best suited for distinguishing between two similar species of bacteria. True Correct! Growth media does not contain restrictive factors, while selective media is best used to encourage the growth of one microbe while simultaneously discouraging the growth of the other. Since two similar species of microbes are being studied they must be differentiated under simi...
