IDENTIFICATION OF UNKNOWN BACTERIA USING BIOCHEMICAL ANALYSIS
Introduction:
Bacteria play an important role in human life; they play a major part in decomposition of organic material, they are present in our digestive tract, some even fix atmospheric nitrogen for the plants. But at the same time there are many species of bacteria which can cause harm to living organisms. Identification of these bacteria plays a vital role in medicine and biological sciences. The identification can be done by two ways, either by performing biochemical tests or by sequencing the bacterial genome. For this experiment I conducted various biochemical tests to identify the given unknown bacteria. The experimental unknowns were 7 different bacteria namely: Bacillus sp., Micrococcus luteus, Staphylococcus epidermis, Streptococcus lactis, Pseudomonas sp., Escherichia coli, Enterobacter aerogenes. Biochemical tests usually interact with the bacterial metabolites (chemical reactions done by the bacteria) to identify a specific bacterium or sometimes a specific genus of

For the Oxidase test, first I took a substantial amount of bacterial goober using the loop from the given petri dish (this does not need to be from an isolated colony). I then placed this goober on the piece of filter paper and added a few drops of oxidase reagent to it. I observed for few seconds to see if there was any color change and wrote down my observation. After that, I obtained a F agar petri dish and streaked it with the unknown bacteria using a sterile loop. The petri dish was incubated for 24Hrs at 35oC. The petri dish was observed to see if there was any bacterial growth and once the whole dish was full of bacterial colonies, it was observed under an UV lamp to see if there was fluorescence or not. I decided not to do the IMViC tests because the first two tests concluded on what the unknown bacteria
Unknown Microbial # 398
532 Words | 3 PagesMethods 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.

1054 Words | 5 PagesIf the catalase enzyme is present in the organism being tested then when in the presence of hydrogen peroxide (H2O2), the enzyme will convert the solution to water and oxygen, this can be observed bubbling of the organism when hydrogen peroxide is added to the test tube. EMB agar is both a selective and differential media; it is selective for gram-negative cells, in that when a gram-positive culture is plated there will be no colonies after incubation because the eosin and methylene dyes prevent the growth of gram-positive organisms, the
Unknown Bacteria Lab Report
1200 Words | 5 PagesThe purpose of this lab report is to employ a myriad of skills, tools and, methods learned throughout this semester to perform the appropriate tests for the identification of the assigned unknown bacteria. Add more background information here!!! The most important tools and techniques used during this identification include aseptic technique, microscopic examination and, the use of selective and differential media. Aseptic technique is an important tool for microbiologists. It is imperative that aseptic technique is maintained throughout the length of any test to avoid any cross-contamination that may lead to inaccurate results.

A presence of bubbling was observed. 2.11 Starch Hydrolysis
Staphylococcus Epidermidis Essay
771 Words | 4 PagesMy bacterium turned out to be gram positive. When conducting these tests, I only had to do the coagulase test and the catalase test because when doing the catalase test, the reaction was that it had bubbled. If it did not bubble, or have a positive reaction, then I would not have had to do the coagulase test. Also, since my bacterium caused a positive catalase test, I only had to do the coagulase test and no other tests. This is because with staphylococcus organisms, these are the only tests

It was accepted because when pH were changed to a variety of levels the transmittance began to get higher reaction rates. The increased absorbance means greater amount of product and a higher reaction rate will be produced.
Unknown Microbiology Essay
517 Words | 3 PagesBeing able to identify unknown microbes from systematic testing is what makes the field of microbiology so important, especially in infectious disease control. Using the testing procedure laid out by the microbiology field we are able to identify unknown bacteria present in our everyday lives, and along the way learn a lot about their characteristics that separate them from other types of bacteria. Being able to do this is vital in order for us to understand why microbes are present in certain places, how they are able to grow and what restricts their growth, that way they can be combatted if necessary. These techniques for determining unknowns are also important for isolating and testing infectious disease microbes in order to prevent spreading. Another important aspect of being able to identify unknown microbes is the

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

Kirby Bauer Diffusion Test Lab Report
624 Words | 3 PagesAseptic technique was initiated at the beginning of this experiment by cleaning the work surface with disinfected wipes. Personal protectives equipment was also worn. The material utilized in this experiment was: S. epidermidis culture broth, sterile cotton swab, streak plate, forceps in 70% alcohol, a lit tea light, and the three antibiotic disks (novobiocin, gentamicin, penicillin). The first step, I divided a plate into three quadrants and labelled them with the different antibiotic names. Using the lit tea light, like a bursen burner, I flamed the mouth of the S. epidermidis culture.

Its morphology is cocci arranged in cluster. However, during decolorizing process, I put too much alcohol to the crystal violet-iodine complex making the color overly removed. That led to the result of my gram positive has slightly redish
