Movie Time

Last Thursday, the 3rd, we started to watch the movie Outbreak. It shows how a bacteria can quickly spread throughout many different areas of the world. Today we inoculated a nitrate broth tube to see if our unknown is able to reduce nitrate to either nitrite or nitrogen gas. We then did the indole test to see if our bacteria can split tryptophan into indole and pyruvic acid. Then we did the citrate test to see if it uses citrate as a source of carbon and energy. The urea hydrolysis test was next. This was used to see if our unknown can hydrolyze urea. Then we streaked a plate with our unknown and placed penicillin, vancomycin, novabiocin, tetracycline, erythromycin, chloramphenol, and neomycin patches in a pattern to see which antibiotic our unknown is sensitive to. Then we finished the movie. :)
