Name Date Lab Section I was present and parlormed this axerdse (ribals) DATA SHEET 2-1 Ubiquity of Microorganisms OBSERVATIONS AND INTERPRETATIONS 1 Usa the circles below as Petri dishas. Then, for each plate, very unafull Labal the the side. Simple line drawings are accoptable, but do them with care. Chicken scratches are not very usaful Labai the according to incubation time, temperature, and source of Inocuium. Also inciude other useful coiony Infermation, such as below as Petri dishas. Then, for each plate, choose two different colonies and draw each as seen from abowe color and relative abundance. 2 Save the plates for Evercise 2.2.

Consider plates 2 and 3 (table top). a. Did yow get different-appearing colonies on plates 2 and 3 If so, explain why 2 b. What is the likely source (reseoir) of organisms that gretw best at 35C, and hou do th ey sTUe t o temperature without nutrients? 4 Suppose plate 4 (cough) has ro growth after incubation. It is hrighly unlikely the cougher has sterile coughs Suggest reasons why no growth uas recovered on the plate. 5 The plates you are using for this lab will be autoclaved to completehy sterilize them. The measures taken to disinfect the tabletops (the source of the organisms on plates 2 and 3) are not as extreme. Why? MICROBIOLOGY: Laboratory Theory & Application, Brief
