Biochemical Testing for Microbial Identification

Culturing Microbes Lab Report


For this task, complete the Aseptic Technique and Culturing Microbes LabPaq experiment found at the web link below. Next, you will complete the microbial identification experiments listed below and write a lab report discussing the results of these experiments.

Microbial identification experiments:

• Biochemical Testing for Microbial Identification—Methyl Red, Voges-Proskauer, and Catalase LabPaq experiment using Escherichia coli and Staphylococcus epidermidis

• Biochemical Testing for Microbial Identification—Carbohydrate Fermentation LabPaq experiment using Saccharomyces cerevisiae and Staphylococcus epidermidis

• Bacterial Identification through Functional Media—Motility Testing LabPaq experiment using Escherichia coli and Staphylococcus epidermidis

Note: You will need the Staphylococcus epidermidis culture for Task 3, so do not discard it.

Your lab report should be written in complete sentences and in paragraph form. Your report should include the following sections:

• introduction

• materials and methods

• results

• discussion

The information required for each section is outlined in the requirements section below.


Your submission must be your original work. No more than a combined total of 30% of the submission and no more than a 10% match to any one individual source can be directly quoted or closely paraphrased from sources, even if cited correctly. Use the Turnitin Originality Report available in Taskstream as a guide for this measure of originality.

You must use the rubric to direct the creation of your submission because it provides detailed criteria that will be used to evaluate your work. Each requirement below may be evaluated by more than one rubric aspect. The rubric aspect titles may contain hyperlinks to relevant portions of the course.
