How to Write a Lab Report in Microbiology

The following tests according to the lab manual were performed: gram stain, fermentation tubes, methyl red, vogues proskauer, sulfur, indole, motility and growing it up on MacConkey agar. The gram stain was performed incorrectly the first time. This is because the decolorizer was not on the bacterium slide for long enough, giving a false outcome.

This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor.

Many tests were completed on the unknown such as gram staining and inspection under microscopes to find whether the bacterium is gram positive or gram negative. Chemical resistance tests were also performed to see if certain chemicals affected the unknown growth or if it didn’t affect the bacteria at all. Each biochemical test

When your lab report is complete, submit this document to your instructor in your assignment box.

For the temperature test each bacteria was placed on a nutrient agar and incubated for either 10, 20, 30, 40, or 50 degrees Celsius for 48 hours. During the pH test, each organism was placed on four agars varying in pH level from pH 2, 4, 6 and 8 and incubated near 37 degrees Celsius for 48 hours. For the osmotic pressure test, each organism was placed on four agars one each containing 2%, 5%, 8%, and 11% NaCl concentration levels. These were incubated near 37 degrees Celsius for 48 hours. The results of the tests are recorded in Tables 1, 2, and 3. All tests were performed according to the instructions provided in Leboffe & Pierce(1). The biochemical tests used on both unknowns and the ubiquity are:

The alternative, no bubbles produced, meant a catalase negative organism. For oxidase, as stated in the lab manual, a sterile toothpick was used to obtain growth from the quadrant streak and placed onto a paper strip. This test will show a color change for organisms that produce cytochrome

The decolorized Gram negative cells are stained pink. With the results from the Gram stain I was able to follow the “Unknown Identification Flowchart” to the next step, which was to prepare for the Starch Hydrolysis Test by inoculating a starch plate.

There are many different forms and styles used in writing. Writing is a form of communication that is used to document and express ideas people have. Through the years as people grow and learn knew ways of writing, writing awareness of a person will evolve into a much higher level of thinking. From the first term paper a person writes in high school to the papers they hand in at the college level, the writing will have matured over the years. The authors of writing develop new and more sophisticated ways in expressing themselves through the words they use in writing. Throughout history writers have found ways in which they can achieve the goals of gaining the readers attention and keep them interested. A good form of

During my student teaching experience and my first year of teaching, I noticed that many students struggled to coherently write about their results or conclusions at the end of a lab. Therefore, during my second year of teaching, to help my students strengthen their writing skills, I decided to incorporate a few lessons on the procedures of writing a lab report. Once we had covered the essential parts of the “Scientific Method,” we segwayed into discussing the importance of lab reports in the real-world. We talked about how scientists use them to communicate results, as well as discussed how writing them would develop and sharpen my student’s scientific inquiry skills and scientific thinking. Initially, writing a lab report is a very
