4 stages in a bacterial growth are: - Lag phase, Exponential (Log), Stationary, Death Acid-fast staining - (differential staining) Add carbol fuchsin (primary stain) then heat over flame for few minutes. 2.Wash and then add a decolorizer (5% HCl and 95% ethyl alcohol) to remove primary color from nonacid-fast organisms. Acid-fast bacteria will retain the primary color. Alexander Fleming - discovered penicillin (the first antibiotic discovered!) Anton Van Leeuwenhoek - was the first to obser...
