Gram-positive bacteria

Each structure allows the bacterium to carry out different functions. However, some bacteria may occur more than once, or have a trait in common relating to another bacterium. Additionally, under a microscope, each bacterium tested either positive or negative with a gram stain test. As shown in Table 1, of Experiment A, the Staphylococcus Aureus consisted of a perfect circle shape, it had tested positive for the gram-stain test which meant that the stain of the bacterial cells was purple, and…

teichoic acids that used by bacteria in cell wall synthesis. Teixobactin will form a stoichiometric complex by binding to a highly conserved motif of…

the Bacteria Pseudomonas aeruginosa During microbiology lab, an unknown bacteria culture in liquid broth was assigned to be identified by conducting a series of various tests. Nearly twenty different tests were conducted on the bacteria, but the most important of these was Gram staining test, gelatin stab test, and oxidase test. The results of these three tests allowed for the determination of the bacteria genus and species. The first test conducted was Gram staining. In the process of Gram…

Introduction: Bacteria create an enormous domain of prokaryote microorganisms that are diverse and abundant in most habitats on Earth. In fact, bacterial cells drastically outnumber somatic cells just on the external part of the human body compared to somatic cells within the whole body of a single individual. Bacteria are found just about anywhere on earth and are usually alongside other microorganisms including: mold spores or yeast cells, creating some difficulty when trying to distinguish…

learn about an unknown species of bacteria along with learning some techniques when it comes to process of elimination in a scientific study. To do this, many different tests were completed to help rule out species that were provided on a sheet of paper listing the possible candidates for the unknown microbe. The Bergey’s Manual of Determinative Bacteriology flow chart was also used to narrow down choices as tests were completed, along with a flowsheet of gram positive and negative microbes…

The endospore is a quiescent and tough structure that is form by some gram-positive bacteria that allows them to survive in harsh and extreme environments. Because only some genera of bacteria produces the endospore, its identification is important in helping us identify some bacteria. 2. What type of eukaryotic cells did we observe and how were they different from the prokaryotes we have looked at? (Be sure to include ways they are different internally as well as any observable traits) The…

Objective Review: 1. Describe the purpose for using aseptic technique in collecting specimens Aseptic technique is used to prevent contamination of specimens by pathogenic organisms. The goal of maintaining asepsis is to not introduce any other organisms to the patient and prevent the spread of any organisms the patient may be carrying. Certain practices are used to help decrease this from occurring including cleaning, sanitizing, and disinfecting. Aseptic technique is an important process to…

of how I identified Bacillus cereus. a. First, I performed the gram stain test, I then went on to do the spore stain. b. The results I obtained from the gram stain were gram positive rods, I could tell they were positive by the purple color to them and the rod shape by the comparison provided in the lab manual (Wilkosz, Peterson). After I confirmed the results I performed the spore stain, which indicated that my sample was positive so it contained endospores. The sample should have shown that…

Materials and method Microorganisms are classified in to the three domains of life. The organism that is predominately found in our environment is bacteria closely followed by archaea and eukaryote. Although, microorganism might seem similar, they are different interims of their structures, biochemical composition, and the habitat they adopt. Conducting an extensive test on microorganism has many benefits. We can protect our self’s from different types of infectious disease. In the unknown…
