Gram Staining Gram Staining is a method of differentiating bacterial species into two large groups (Gram-positive and Gram-negative). Gram Staining is a way to separate one large group of bacteria into two. Crystal violet is used to dye the cells‚ which is the primary stain. Those that retain the color are grouped as Gram-positive‚ and those that do not retain the color are grouped as Gram-negative. Many of the Gram-negative bacteria are pathogenic‚ making this process useful for detecting infections

Ten Replicates on ten Petri dishes were prepared for each bacteria. Pure cultures of the three bacteria were spread on the replicates. After extracting the needed substances from the kamias leaves and fruit extract‚ the researchers were able to begin the experimentation.

antibiotic that works on gram negative bacteria. Gram-negative bacteria are bacteria that do not retain crystal violet dye in the Gram staining protocol whereas Gram-positive bacteria are those that are stained dark blue or violet by Gram staining. The bacteria we used were E-coli that are a gram negative bacteria and the only antibiotic out of Penicillin and Streptomycin that will work is Streptomycin. Penicillin is also effective antibiotic but it will only work on bacteria that Is gram positive because

12th December‚ 2014 MCB 3020L- Section 018 Unknown #16 Abstract This report contains the background information on gram positive and gram negative bacteria‚ which will aid in understanding the use of specific laboratory experiments to distinguish between the two types of bacteria. Included are the materials and methods used to identify the gram positive and gram negative bacteria and methods which also differentiate between microbes of each group. The implications of the methods of identification

Introduction: The purpose of this lab is to use staining techniques and biochemical testing to identify an unknown bacteria using Bergey’s manual. Bergey’s manual of Systematic Bacteriology is a dichotomous key primarily used to identify a bacterial species. Biochemical tests are used to differentiate different species of bacteria. These tests are effective in determining the characteristics of the microbe being tested. Such characteristics include citrate utilization‚ gelatin hydrolysis‚ nitrate

| Gram Negative Unknown | Biology 3444-006 | | Lena Wallace | 11/7/2011 | | Abstract: The purpose of this lab was to identify an unknown bacteria culture using differential tests. The identification of the unknown culture was accomplished by identifying the bacteria based on its specific metabolic characteristics and morphology. It is suggested that culture 11 is a sample of Enterobacter aerogenes. Introduction: This experiment was centered on metabolic and biochemical testing

Bacterial Smears Are Fixed before Staining to? Answer It is important to heat fix the bacterial smear before staining so as to‚ kill the bacteria‚ firmly adhere the smear on to the microscopic slide to prevent washing off during staining‚ and to allow the sample to readily take up the stain. Reference: www2.hendrix.edu What is the purpose of heat- fixing the smear? It helps the cells adhere to the slide so that they can be stained. The purpose of heat fixing is to kill the organisms without

After performing various tests over the course of a few weeks on our unknown‚ we came to the conclusion that our unknown organism is Klebsiella pneumoniae (K. pneumoniae). K. pneumoniae is a gram negative bacillus shaped microorganism. We observed that K. pneumoniae is a nonmotile organism. We performed multiple tests on our unknown culture‚ therefore we are very confident that it is correctly identified. We identified that K. pneumoniae
