6 Were the three different streak methods appropriate to the cell densities recovered? I Most colonies on streak plates grow from isolated colory-forming units (CFUS). On rare occasions, however, a colony can be a mixture of two different organisms. If a culture is started from this colony (thinking it is pure), correct identification will be next to impossible because the extra organism could confound the identi- fying test results. How could you verify the purity of a colony? (The answers may vary depending on what experience you have had prior to performing this exercise.) If you found the colony to be a mixture of organ- isms, what could you do to purify it? 42 MICROBIOLOGY: Laboratory Theory & Application, Essentials
