Week 6


Week 6
10/3/13

Last Tuesday we inoculated a tube of nutrient broth with our unknown bacteria sample that we received in class. We then incubated the broth solution at 37' C for the remainder of the week. 
We spent today's class streaking the same unknown bacteria over various mediums, to see which enzymes our bacteria expressed. Bacteria can be classified is by these enzymes, bringing us closer to identifying our sample.

We inoculated bacteria in litmus milk

and gelatin,


and streaked it over skim milk, starch, and spirit blue (lipid) agar plates.







We will incubate these samples at 37'C until our next class.
