Applying Staining Techniques to View and Identify Bacteria Essay

accostThe main objective of this lab was to identify different bacteria by simple, negative, and gram staining. To view each bacteria cell, the bacteria was transferred aseptically to a slide, and they were past viewed by using oil immersion, by a light microscope. From this lab, it was determined that E. coli and B. megaterium argon gram negative and B. subtilis and S. Marcesans are gram positive.IntroductionThe intend of this lab was to view the different characteristics of bacteria by applying various staining techniques. It is alpha to know the make up if a certain bacteria so an antibiotic may be engineered to destroy the bacteria. From the gram stain, it was achievable to determine which bacteria was gram positive or gram negative. This is important because gram-negative bacteria are generally more toxic (due to the lipopolysaccaride) are resistant to antibiotics than the gram-positive bacteria.MethodsThe materials used for this lab were1.A light microscope2. quater nion glass slides3.And inoculating loop4.A Bunsen Burner5.Bacteria (E.coli, S...
