I have homework lab is very Semple Steak plate method for isolation of bacteria. Modified for home preparation during COVIDREAD THIS WHOLE DOCUMENT FIRST. BEFORE YOU BEGIN ANY WORK!GOAL: the intention. Allow student to gain some experience and familiarity with inoculating a petri plate in order to isolate the species from a body sample. Students will use tryptic soy agar plates (college-provided) and cotton swabs (student-provided) to practice inoculating (=placing the sample on the plate)
swab.ABOUT THE PETRI PLATE: Petri dishes are special plastic containers. In Microbiology will be make into Petri plates when sterilize agar media are pour in and allow to solidify. They consist of a top and bottom, the bottom being where the agar medium. It is poured, and the top is the lid. The lid is not tight fitting to allow for easy opening and closing during the inoculation process. The lid simply sits by gravity over the plate bottom (containing the agar) to prevent things from falling on the agar surface.
If that thing is a microbe, the lid protects against growth of that unwant introduce microbe; microbes we do not intentionally put on media for inoculation are call contaminants. You could think of contaminants like weeds in your garden–they just seem to pop up, and were not put there, and are, therefore, unwant! Plates are always store/place upside down—this prevents any condensation (that forms from trape water vapor) from falling on the agar surface. Wet agar surfaces don’t allow bacteria to grow at all, or to grow well (not in the pattern intended).
