The lab techniques and procedures used throughout this experiment were from McDonald’s laboratory manual (4). To start, the two unknown bacteria had to be successfully isolated. Using a wire loop, a small sample of the numbered test tube was plated on a nutrient agar using the quadrant streak method (4).
Unknown Bacteria Lab Report We were instructed to run tests on an unknown sample of bacteria in order to determine what we had.
The two streak plates made from the mixture of unknown bacteria showed two different colony morphologies. Colonies of Bacteria A were translucent in color, circular in form, with entire margins and a smooth surface. Colonies of Bacteria B were cream colored, irregular in form, with undulate margins and an umbonate surface.Since the sample contained two unidentified bacteria, the first step was to isolate each bacterium using streak plate technique. Tryptic Soy Agar (TSA) plate, and differential media such as mannitol salt and Eosin methylene blue (EMB) were used for isolation streak technique.HOW TO WRITE AN UNKNOWN LAB REPORT IN MICROBIOLOGY GENERAL Unknown reports in microbiology are written in scientific format. Scientific writing is written differently from other types of writing. The results of the exercise or experiment are what are being showcased, not the writing. The purpose of scientific writing is not to entertain, but to inform. The writing should be simple and easy to.
Gram Negative Unknown Lab Report April Smith August 1, 2014 Unknown 20 Abstract The bases of this experiment was to discover the identify of the unknown from three possible specimens: Klebsiella pneumonia, Escherichia coli, and Enterobacter aerogenes.Read More
This sample paper on Identification Of Unknown Bacteria Lab Report offers a framework of relevant facts based on recent research in the field. Read the introductory part, body, and conclusion of the paper below. Not all of these tests were performed on every culture, as some were used only for gram positive or gram active bacteria.Read More
For the morphology of my unknown bacteria, I anticipated that it will be round formed staphylococcus. In reality my unknown was a gram negative grouped bacillus. Keeping in mind the end goal to truly separate my unknown microbes, I needed to record my results and contrast it with a spreadsheet agenda on my lab manual. When I investigated my SIM.Read More
Unknown Lab Essay. In this lab report a number of tests and results will be discussed. Unknown labs are performed for many reasons ranging from figuring out the causative agent in a diseased patient, to knowing the correct microorganism to use when making certain foods and antibiotics. Unknown labs are a key to testing the knowledge a student.Read More
Unknown Bacteria Lab Report Essay.Introduction The purpose to this lab was to isolate and identify two unknown bacteria from a mixed culture provided to us by our instructor. This study was done by applying all of the methods that have been instructed on thus far in microbiology laboratory class.Read More
Order Essay The two streak plates made from the mixture of unknown bacteria showed two different colony morphologies. Colonies of Bacteria A were translucent in color, circular in form, with entire margins and a smooth surface. Colonies of Bacteria B were cream colored, irregular in form, with undulate margins and an umbonate surface.Read More
The Unknown Sample Lab Report (sometimes called Unknown Lab --or Laboratory-- Report) is, as the name suggests, a report written after identifying an unknown sample in the microbiology lab. Students are typically handed one or more vials containing a mystery bacterium, and have to conduct tests to identify what this bacterium is. After the experiment is over, they write a formal report about.Read More
Since the sample contained two unidentified bacteriums. the first measure was to insulate each bacteria utilizing streak home base technique. Tryptic Soy Agar (TSA) home base. and differential media such as Osmitrol salt and Eosin methylene blue (EMB) were used for isolation run technique.Read More
The methods that have been learned so far in identifying bacteria were applied to this unknown. Procedures were followed as stated in the lab manual and biochemical test handouts. The first procedure that was done was a gram stain followed by a streak of the unknown on a TTS plate in order to determine the gram reaction and observe the colony morphology.Read More
Unknown Lab Report. Unknown Lab Report April 25th, 2006 Introduction The purpose of this lab was to identify two unknown bacteria cultures using various differential tests. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic.Read More
