Microbial Isolation

Isolation of the microorganisms in microbiology is the process of developing a pure culture by separating one species of microbe from a mixture of many other species. A pure culture is a culture that contains only one species of microbe.

Question

Which stain is used to distinguish differences between the cell walls of medically important bacteria?
a. simple stain
b. acridine orange stain
c. Gram stain
d. negative stain

Definition Definition Technique that uses crystal violet or methylene blue as primary staining colors to distinguish gram-positive from gram-negative organisms. Under a microscope, the gram-positive organisms appear purple-brown, retaining the primary color. Gram-negative organisms appear pink or red as they do not acquire the color of the primary stain.
