Unable to read the Gram Stain at first it was later confirmed that Unknown #7 was a gram negative bacteria. When introduced to Starch Unknown #7 produced no zone of clearing showing that it did not contain the enzyme amylase. When introduced to the Lipid Unknown #7 did produce a zone of clearing indicating that it did contain the enzyme lipase. When introduced to Casein Unknown #7 produced no zone of clearing indicating that it did not contain the enzyme protease. When streaked onto the Gelatin‚

Experiment H: Identification of an Unknown Organic Compound The objective of this lab was straightforward. We were given an unknown compound and we were to perform an IR spectroscopy and as well as NMR spectroscopy. With the IR spectroscopy‚ I was able to name the functional groups I have on my compound and further confirmed my assumptions by looking at the NMR spectroscopy after. The unknown number I was given was number 203. The molecular weight of the compound was 121. From the molecular weight

MIC 230 Unknown Identification Report The objective of this experiment was to identify an organism from a mixture of two unknown bacterial species. In order to accomplish this‚ I first plated my unknown mixture on Tryptic Soy Agar (TSA)‚ Columbia Naladixic Acid (CNA)‚ and MacConkey’s Agar (MAC) plates. After 48 hours of incubation‚ it was unclear that two different bacterial colonies had grown on my TSA plate. Only one type of colony was evident. However‚ it was apparent that I had successfully
