Analysis of Major Unknown 3C Summary: A series of tests was done with Microbe 3C. A Gram stain was done and the sample was gram positive. A streak plate was completed revealing that the microbe was clear/white in color, margin was entire, shape was circular, elevation was convex/raised, and the opacity was translucent. The last test done was the sucrose test. It starts orange and turns yellow positive for microbe 3C Klebsiella oxytoca (Professor Brady, Personal Communication). Procedure 1 Gram stain: Purpose/ Introduction: The Gram stain reveals whether a microbe is gram positive or gram negative. It also reveals the shape and arrangement of the microbe (Professor Brady, Personal Communication). Of the forty-three possible microbes the following are gram positive: Bacillus cereus, Bacillus circulans, Bacillus coagulans, Bacillus megaterium, Bacillus subtilis, …show more content…

The following was eliminated because they are gram positive: Bacillus cereus, Bacillus circulans, Bacillus coagulans, Bacillus megaterium, Bacillus subtilis, Bacillus thuringiensis, Brevibacillus brevis, Geobacillus stereothermophilus, Lysinibacillus sphaericus, Clostridium perfringens, Corynebacterium pseudodiphtheriticum, Listeria monocytogenes, Lactobacillus casei, Enterococcus faecalis (Streptococcus), Streptococcus lactis (Lactococcus), Streptococcus mutans, Streptococcus pneumonia, Micrococcus (Kocuria) roseus, Sarcina lutea (Micrococcus luteus), Sporosarcina ureae, Staphylococcus aureus, Staphylococcus epidermidis, Staphylococcus saprophyticus, and Rhodococcus rhodochorous. The remaining microbes are gram negative: Alcaligenes faecalis, Rhizobium radiobacter, Salmonella typi, Serratia marcescens, Shigella flexneri, Yersina pseudotuberculosis, Erwina persicinus, Serratia liquifacens, Halobacter salinarium, Enterobacter aerogenes, Eschirichia coli, Flavobacter capsulatum,

Unknown Microbial # 398

532 Words | 3 Pages

Methods Unknown microbial #398 went through several of tests in order to identify its characteristics when isolated from a urine sample of Doris, a 64- year old patient with a kidney infection. To identify unknown #398, must prepare a working and a reserve stock by the inoculation from a broth culture and by quadrant streaking method on a PEM and EMP plates. The following test procedures were incubated at 37°C for 48 hours for observation and identification for unknown #398. The identification of unknown #398 followed test procedures from Brown1.

Alcaligenes Faecalis Experiment

636 Words | 3 Pages

According to the series of test that my group ran for our unknown specimen, we had a match with the bacteria known as Alcaligenes Faecalis. This bacterium belongs to one of the major group of gram-negative bacteria (Phylum Proteobacteria). Alcaligenes Faecalis (Genus, species) is a rod shaped (bacillus), 0.5-1.2 x 1.0-3.0 µm, round with scalloped margin (colony configuration growth), motile (with one to nine peritrichous flagella), gram-negative, non-fermentative bacteria, obligate aerobic, having oxygen as the principal terminal electron acceptor in the electron transport chain (ETC). We consider we have a match with the species Alcaligenes Faecalis because of the following reasons: Fermentation tests performed (Durham sugars) were negative, which indicate that our bacteria use a different metabolic means for growth (non-fermentative gram-negative bacteria).

Bio 13 Lab Report

1009 Words | 5 Pages

In this three-week long experiment conducted in the Bio 13 Lab, we were able to analyze a single nucleotide polymorphism (SNP) in our own genomic DNA and then determine our genotype at this specific SNP. In week one, we extracted genomic DNA from our cheek cells with swabs and prepared our DNA for PCR (Polymerase Chain Reaction) that would amplify the region with the intended SNP of interest. After one week and after the PCR was run outside of the lab section, the resulting PCR product was purified and treated with restriction enzyme Ahdl in order to prepare for the final analysis of our genotypes. In the third and final week of the project, we analyzed our PCR products by means of agarose gel electrophoresis. By the conclusion of the experiment, we had completed the analysis at the SNP of interest and determined our genotypes for this SNP.

The second ½ of the organism was used for gram staining. The gram stain method was performed on the unknown organism per lab manual page 42 and two gram stain reactions were identified. Organism B was gram positive cocci in grape like clusters. Because organism B was positive I could eliminate Escherichia coli, Enterobacter aerogenes and Proteus vulgaris because these bacteria would be rod shapes. Organism A was gram negative pink rod shaped and because of gram positive morphology I could eliminate Staphylococcus aureus, Streptococcus lactis and Bacillus subtilis.

The unknown bacteria was then tested on multiple selective and differential media. Growth was present on the MacConkey Agar and the colonies were the same color as the plate, which told me my bacteria was gram negative and did not ferment lactose. There was no growth on the Mannitol Salt Agar, and this told me the unknown was not salt tolerant and did not

Unknown Culture Lab Report

Identification of bacteria within Unknown Culture #21 In this experiment, an unknown culture of two different types of bacteria was assigned to each person, a number of tests were performed to isolate and identify these bacterial cells. Based on knowledge from the previous experiments completed in lab, a basic understanding of each type of bacteria was used to create a flow chart that would aid the process of identifying the unknown bacteria within the culture. A gram stain that is performed initially will narrow down the types of tests certain bacteria will and will not respond to. In addition to the gram stain, some of the tests that were used include, a catalase test, an Eosin methylene blue (EMB) agar test, a bile esculin test, and a 6.5% sodium chloride (NaCl) test.

In this experiment, we cultivated an unknown specimen containing two microorganisms. The purpose of this experiment was to use a variety of biochemical test previously learned in the lab to identify the unknown bacteria. The identification of unknown bacteria is a major part of microbiology. Microbiologist observe samples such as blood and sputum in the laboratory for the presence of microorganisms. Identifying unknown bacteria is extremely important in clinical settings because it helps physicians find treatment for infections.

Blast Off Lab Report

In the “Blast Off” lab, we had launched a foam rocket into the air by pumping air into a nozzle, shooting the rocket up, and then recording the time from launch to when it hit the ground. I have learned and now understand the mechanics of kinetic and potential energy. The experiment I had conducted relates to energy in that as we observed the rocket, its energy was constantly transforming as it was in motion. Kinetic energy is an object’s energy based on its motion. Potential energy is energy based on an object’s shape or position.

Microbiology Unknown Lab Report

Introduction: Microbiology is the study of the microbial world, which is composed of microorganisms that are too tiny to be seen with a naked eye. This project demonstrates the significance of correctly identifying unknown organisms with methods and techniques acquired in the laboratory as they can make or break one's ability to accurately isolate and identify various species. Studying microbes enables oneself to have an insight on not just their structure or how they function, but how they have an impact on organisms and their environment around them as they can be found nearly anywhere. The importance of the process of identifying unknown bacteria vary from determining the causative agent of a disease, to testing if a specific food or fluid is safe to consume, and simply knowing what is present

After a gram stain was done unknown #257 was identified as a gram positive organism because when observed under the microscope the organism appeared purple with cocci in clusters. The organism was also catalase positive which means that it produced enzyme catalase and bubbled when hydrogen peroxide was added to it. Three test were conducted based on the result of the gram staining procedure. Blood agar with a Novobiocin disk was chosen as well as DNase (DNA) and Mannitol Salts (MSA) agar. The Blood agar is a bright red, opaque plate and the streaking or the inoculation technique was a modified streaking for isolation with a heavy quadrant one.
