Document Summary
Microorganisms are of abundance and located virtually everywhere on planet earth. These organisms, much smaller than the eye can perceive, are considerably diverse. Studying microorganisms involves the application of various aseptic techniques which allows us to work with non-contaminated specimen. Due to the countless number of microorganisms present at any given time, exposure of the agar plates to the air will allow species to accumulate on the plate. Sterile swabs will also easily collect numerous specimen from around the room and on our body. Incubation of these plates will promote growth and colonies can then be studied. Five total agar plates were used, three of which were brain heart infusion agar (bhi) plates, capable of growing bacteria, and two of which were potato dextrose agar (pda) plates, capable of growing fungi and yeast. Each plate was labeled on the bottom with a permanent marker and our initials, date, media type.
