Escherichia coli Microbiology Lab NAS 185-14L Introduction In this lab experiment we did several test to determine what our unknown bacteria was. To determine this we recorded the results of how the bacteria reacted to different media. Depending on the results of each test we could narrow down the different bacteria to determine what our unknown is. This experiment will also determine if our bacteria is a fermenter of sugars and if it is catalase positive. If the bacteria is

Project 1: Antimicrobial Activity of Soil Isolates John Franklin Farrar Department of Biology and Microbiology and Biology Address BOX 22750 BOWEN HALL‚ RALEIGH‚ NC‚ 27607 Abstract: Isolation and characterization of microorganisms is a practice that aids in Increasing ones knowledge of a laboratory setting and it helps improve on Using sterile technique. Isolates of soil microbes can be categorized and Characterized based on a number of criteria ranging from gram-staining

Materials: 4 sterile cotton swab‚ sterile water in test tube‚ 4 agar plates and 2 blood agar plates‚ wax pencil and labels. Procedure: Appropriately label the cover of each plate as indicated in lab. 1. Determine 2 sampling sources‚ one from your body and one from the surrounding environment. 2. For the first agar plate‚ for sampling from air‚ remove the lids from the plate and allow it to sit uncovered for 15 minutes. 1. For second agar plate‚ open the “stick” end of the sterile cotton swabs to

HYPOTHESIS: Microbial growth will be present in two of the three Agar plates (those containing the food product) due to the suspected presence of microbes‚ whilst the control Agar plate (containing no food products) will remain free of contamination and microbial growth.
