What is the primary stain, mordant, decolorizing agent, and counter stain of this technique? Do we heat fix in here? Describe the organism with purple color. Describe the organism with pinkish red color.A student inoculates Escherichia coli into two test tubes containing the same sterile liquid medium, except the first tube also contains a drop of a chemical disinfectant with an antimicrobial effect. After 24 hours of incubation, the first tube remains clear while the second tube becomes cloudy with bacteria. How would you go about determining if the chemical is bacteriostatic or bactericidal?
