that can assist in identification of bacteria are their ecological habitats and more advanced methods such as genetic and molecular composition. Using various techniques one is able to distinguish and ultimately assign then genus and species of the unknown bacteria. Methods: Gram Staining: The Gram stain separates bacteria in two distinct classes and is also useful in distinguishing morphology. Through this technique one is able to identify bacteria as either gram positive or gram negative. The gram-negative

the density of water and an unknown liquid. Density is defined as the mass of a substance divided by its volume. It is an intrinsive property of matter and is used to specifically characterize substances. III. Procedure: 1.We massed an empty 10mL graduated cylinder to the nearest .01g. 2.Then‚ we filled the graduated cylinder with 4.0-5.0 mL of distilled water‚ 3.massed it to the nearest 0.1 ml and 4. recorded the data. Then to determine the density of the unknown liquid; we repeated the steps

Identifying Unknown Bacteria Using Biochemical and Molecular Methods Beginning of Instructor Pages Instructor Pages - - 3 Purpose The purpose of this lab is to introduce a variety of lab techniques to students working on the common problem of identifying an unknown bacterium. This lab helps students develop an understanding of the biochemical and molecular differences in bacteria and introduces the concept of identifying species based on characeristic gene sequences. Students work through

on human samples collected from different body sites. The tests are used to detect and identify any microorganisms capable of causing disease. Knowing of unknown microorganism is important on how this microorganism works and how it is structured‚ means knowing how it can affect humans. The purpose of this study was to identify an unknown bacterium by applying all methods that were previously conducted and learned in the medical microbiology laboratory class. **Materials

Discussion The possible identity of the unknown organisms in the mixed culture was limited to bacteria that we had worked with previously in lab. Initially a Gram stain was conducted in order to distinguish the unknown bacterium as a Gram-positive and/or a Gram-negative organism (Lancaster and Bennett‚ 2012; Kellenberger‚ 2001). Based upon the results‚ both Gram-negative and Gram-positive bacteria were observed in the unknown mixed culture (Table 1 and Table 2; Kellenberger‚ 2001). In order

James Connors Assignment #1 Hemingway’s ‘Soldiers Home’ is about a man named Harold Krebs. He was a soldier in WWI‚ who came home after the rest of the soldiers had returned post war to a hero’s welcome.
