WARNING!
About these pictures:

Do not try to compare your unknowns with these pictures to figure out your unknown. 
It is a very misleading thing to do.
It is not good to try to compare your current unknown to a small picture that doesn't look exactly the same semester after semester and come up with an answer based on that.
  • Your organisms are grown on tryptic soy agar (TSA). Many of these pictures are of organisms grown on nutrient agar (NA).
  • Organisms can change in appearance based on the age of the culture.
  • Your grade depends on you doing the lab work; don’t guess based on pictures or web sites.
Do not use test answers or charts from other semesters.
  • Batches of bacteria come from different strains and can take on varying characteristics, including colors and growth patterns.
  • We switch batches every semester and your organism will not exhibit the same characteristics as those of previous semesters.
These pictures are made available to you as a convenience.
  • We have created a PDF for you to document organismal characteristics in your exposure to these bacteria prior to your unknowns. You should make one for slants also.
  • Try to understand how to interpret cultural characteristics.
  • Compare these images to the way your organism actually grows or looks.
  • Take good observation notes while you are working with organisms before you start your unknowns.
