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...

Describe Spontaneous Generation and Biogenesis. - Spontaneous Generation was discovered by Aristotle that new life comes from non-living inanimate material; biogenesis is that living organisms are required to produce new life. How was Spontaneous Generation disproved? - Louis Pasteur developed a special flask in 1864 with a curved neck that allowed air in, but would trap any microorganisms. Pasteur's flask was free from microorganisms, even though it was open to the air. For a year, there ...
