Microbiology Lab ReportPractica #1BTC307LAmber AmelingmeierThursday‚ September 18‚ 2008OBJECTIVESIn this lab experiment two different types of bacteria‚ Escherichia coli and Staphylococcus aureus‚ were grown singly and mixed on four different types of agar in order to observe the varying morphologies within the colonies. Resulting data was analyzed to provide understanding of the use of differing culture media and conditions for bacterial growth. RESULTSFour different agar types were used in this

Isolation of Eugenol from Cloves Abstract The experiment conducted‚ isolation of eugenol from cloves‚ is the extraction of the essential oil. To perform this experiment cloves and water were mixed together and heated by a heating mantle in a round-bottom flask. A direct stem distillation took place‚ and the oil product was out aside for a week. After one week‚ the isolation of the eugenol actually takes place. Next the thin-layer chromatographic analysis takes place‚ but the experiment

plates will all yield different forms of growth‚ with different coloration and colony number. It is also predicted that the agar plate media containing the arabinose will grow a green fluorescent color and the (-)pGlo plate with ampicillin will exhibit no growth at all‚ due to the lack of the plasmid that is resistant to ampicillin. The prediction for the other two plates lacking arabinose is a growth of colorless colonies. Multiple medical experiments are credited towards transformation‚ especially
