Gram Staining Lab Introduction Gram staining is a very important technique used in biology labs all over the world. It is a technique used to differentiate types of bacteria using certain physical and chemical characteristics of their cell walls. Gram positive bacteria (which show up purple after the gram staining process) have a very thick layer of peptidoglycan where gram negative bacteria (which show up pink after the gram staining process) have a much thinner layer of peptidoglycan.

Practical One Report Unknown Bacteria Staining Gram Acid Fast Spore The first practical for microbiology was staining of an unknown bacteria. Professor Goode provided an unlabeled bacteria in which each individual were to conduct gram‚ acid fast‚ and spore staining tests from memory. When the gram staining test was conducted a positive results was obtained. When views on oil bacteria appeared purple and rod-like. I noted this result and looked at the lab key to see what the results narrowed my bacteria

Introduction Gram staining was developed by Christian Gram in the 1800’s‚ a Danish bacteriologist. (Smith and Hussey‚ 2005) It was the first differential staining technique and most common used in microbiology. Furthermore‚ bacteria are transparent and cannot be seen through the microscope. For that reason‚ Gram staining is an important tool for distinguishing between two main types of bacteria Gram-positive and Gram-negative. The Gram stain differentiates the Gram positive and gram-negative on
