Observing Microorganism (B)

Part 2 – STAINING Microorganisms are observed and studied with the help of microscopes. However the bacteria have nearly the same refractive index as water, which makes them visually opaque. Hence, the microbial cells are routinely stained for clear microscopic examination. Staining is thus an auxiliary technique used in microscopy and microbiology to enhance contrast in the microscopic images […]
