Document Summary
Lab 1: glo-germ, ubiquity of microbes, aseptic transfer, and streak for isolation. Involves microorganisms posing moderate hazards to personnel and the environment. List the 3 things to complete when you walk into the laboratory. Sharps container slides and broken glass. Biohazard container tsa plates, used swabs, used gloves, anything that has touched the bacteria and/or bodily fluids. Test tube rack tsb test tubes. Trash paper towels, any non-hazardous waste. Complex considered undefined because exact composition unknown. Autoclave: 121 c, 15 psi, 15 min. Turbidity the cloudy appearance of a liquid that is suspended with matter: confirms that bacteria have growth in broth culture. Colony forming units (cfus) define the cell or groups of cells that produces a colony when transferred to plated media. Ubiquity state of being present/ around everywhere. Commensalism synergistic relationship 2 organism in which one benefits from relationship, the other not significantly impacted. Mutualism synergistic relationship between 2 organisms where both benefit part of body.
