Isolation and identification of an unknown bacterium Pillay‚ Esmerelda (209504371) School of Biochemistry‚ Genetics and Microbiology Department of Microbiology University of Kwa-zulu Natal 25 October 2010 ABSTRACT Different types of bacteria in various forms are found all around us‚ and it is a microbiologist’s job to be able to identify these bacteria. Using various staining techniques and physiological tests‚ an isolated bacterium can be identified. In this experiment‚ a single bacterial

Isolation of Bacteria in our Physical Environment Introduction: The purpose of the lab is to apply what has been learned so far in Microbiology‚ and use it to collect and examine microbial species from the physical environment. The physical environment around the lab will be utilized to find out the variety of different microbial species growing in and around the lab. This investigation will help in preparation for the individual projects that will be done at the end of the semester. Materials

Identification of A Mixed Culture Unknown An experiment such as this one serves the purpose of allowing us‚ the students‚ to apply what we already know about any organism and any laboratory procedure to the difficult task at hand. It is possible to identify a mixed culture by running familiar experiments on the unknown bacteria and taking information already known about specific bacteria and applying it to the results. This helps to slowly eliminate any bacteria that do not correspond with the

Bacterial Smears Are Fixed before Staining to? Answer It is important to heat fix the bacterial smear before staining so as to‚ kill the bacteria‚ firmly adhere the smear on to the microscopic slide to prevent washing off during staining‚ and to allow the sample to readily take up the stain. Reference: www2.hendrix.edu What is the purpose of heat- fixing the smear? It helps the cells adhere to the slide so that they can be stained. The purpose of heat fixing is to kill the organisms without

Introduction The purpose of this project was to detect which organism we had in our unknown mixed culture tube by running a series of experiments to detect which specific Gram negative organism we had. To detect your gram positive from the mixed culture was given as extra credit points also. A Gram stain was performed and isolation streak plate in order to isolate and observe the unknown organism. Before the series of test‚ a dichotomous key had to be written up in order to know what steps

Synopsis on TITLE: Isolation and Characterization of Potential Phosphate Solubilizing Bacteria from Wheat (Triticum spp) of Bangladesh Introduction Wheat (Triticum spp.) is a cereal grain‚ originally from the Levant region of the Near East and Ethiopian Highlands‚ but now cultivated worldwide. In 2010 world production of wheat was 651 million tons‚ making it the third most-produced cereal after maize (844 million tons) and rice (672 million tons)(FAO‚2010). In Bangladesh‚ wheat cultivation

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

ISOLATION OF INDIVIDUAL BACTERIAL COLONIES ON SOLID MEDIA Robert Koch developed a method for isolating pure cultures on solid media in 1883. To this end he added agar (a solidifying agent) to liquid nutrient broth; the nutrient broth supports the growth of a wide variety of microorganisms while the agar provides a solid substrate on which bacteria can be mechanically diluted and therefore isolated as independent colonies representing different bacterial species. The isolation of independent bacterial
