Maura Gongora 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

Title: Observing Bacteria and Blood- Lab #1 Purpose: Being able to learn how to correctly use a microscope and the oil immersion lens to be able to see the prepared slides. Also to learn how to prepare my own yogurt and blood slides. Procedure: First‚ set up the microscope. Clean the ocular lenses and objectives with lens paper. Then pace the prepared e slide on the stage and make adjustments. Turn the rotating nosepiece until the 10x objective is above the ring of light coming through the slide

Accordingto the chemical make up of bacterial cell wall‚ a staining procedure‚ Gram stain‚ helps usclassify bacteria into two subgroups‚ The cell wall can stain either positive or negative‚depending on its chemistry. If the bacteria stains positive it will retain a purple/blue color. If the

Size and morphological analysis The morphology and size of nano-ZrO2 was studied by Field emission scanning electron microscope (FESEM)‚ model JEOL JSM7600F. Scanning electron microscopic (SEM) analysis was done to determine the morphology and pore dimensions of prepared nanocomposites (BNC I-III). SEM was performed using EVO-18‚ Carl-Zeiss instrument. For both of these analyses‚ samples

using Several Microbiology Lab Techniques The purpose of this study was to determine what an unknown bacteria was using several different microbiology lab techniques including an API test‚ an oxidase test‚ a gram stain‚ a hanging drop slide‚ and morphology identification. The unknown bacterium‚ which was contaminated with Serratia marcescens‚ was isolated by streaking the bacteria solution to single colonies. The isolated unknown white bacteria‚ had the appearance of circular form‚ convex elevation

The Comparative Analysis of Simple Staining and Gram Staining Techniques by observing E. Coli and S. Pyogenes under the Compound Light Microscope INTRODUCTION: A German bacteriologist‚ Dr. Theodore von Escherich‚ was the first man in 1885 who discovered the bacterium named Escherichia coli‚ which are gram negative and appears in rod shaped. Most kind of bacteria E. Coli does not cause diseases and some strains indeed are beneficial in helping the process of food breaking down in the intestines
Premium Escherichia coli Bacteria Staining
Purpose: To identify an unknown bacterial specimen using basic laboratory technique and biochemical tests. The unknown bacteria will be one of the following: Enterococcus faecalis‚ Staphylococcus saprophyticus‚ Escherichia coli‚ Enterobacter aerogenes‚ Proteus vulgaris‚ Salmonella [I assume typhimurium]‚ or Shigella [either flexneri or sonnei‚ we used both in our lab during the semester]. Procedure {and observations}: Observe bacterial colony morphology. {Colonies are large‚ beige or cream-colored
