- What makes a culture media as SELECTIVE? Explain and provide examples of selective type of culture media.). Consider a culture medium on which only gram-positive organisms such as Staphylococcus aureus colonies can grow due to an elevated NaCl level. A yellow halo surrounds the growth, indicating the bacterium fermented sugar in the medium, decreasing the pH as a result and changing the color of a pH indicator chemical. This type of medium would be referred to as a(n): A) Selective medium. B) Differential medium. C) Enrichment culture. D) Selective and differential medium. E) Differential and enrichment culture.In zone electrophoresis, why is it possible to isolate the components of a sample and recover them for identification? a) what influences the direction of migration of the components of a sample in zone electrophoresis?
