pigmentation‚ colony‚ margin characteristics‚ elevation properties‚ broth characteristics and agar stroke properties. 2. To examine bacteria growth characteristics on different culture media. Introduction: Bacterial species can sometimes be identified on the basis of how they appear on or in the different media. The pigmentation‚ size and shape of bacterial colonies as they grow on and in agar plates can provide identifying signs. Observing the growth characteristics of organisms in broth

Case Study Report for Unknown #49 A new school for girls was opened in a larger village in Northern Pakistan‚ and the teachers were proud to have convinced many families in the surrounding villages to allow their daughters a basic education. The school was a success‚ and the 6-10 year olds girls quickly learned how to read and write and were even instructed in the sciences. However‚ 2 weeks before summer break‚ many of the girls and the teacher developed breathing problems that included severe coughing

Abstract In an environment isolation procedure‚ experiments under categories‚ such as‚ morphology‚ physiology‚ antibacterial susceptibility‚ selective media‚ and biochemical provide results. Both the unknown isolate and members of the Micrococcus genus were shown to be obligate aerobes. By using staining methods‚ this proved that the organism is gram positive. Morphology‚ such as‚ orange pigmentation and coccus shape provide similarities to the Micrococcus genus. Physiological tests were shown to

be used in this lab to detect nature of the antibody interaction. The orientations of the band will provide more information about the interaction of antibody and antigen. Hypothesis: For this experiment‚ antibodies will be placed in wells on an agar plate‚ surrounded by wells containing serum (proteins‚ antigens etc.). If the antibody interacts with the antigen of surrounding wells‚ then the presence

IDENTIFYING GRAM POSITIVE COCCI As mentioned in Exercise 8‚ “Identifying Gram Negative Rods”‚ identifying bacteria is a common activity in the microbiology lab. Like the game Clue™‚ each time you gather a piece of information to solve the mystery‚ you gather some information that supports some identities and eliminates others from contention. In the lab‚ the process continues as you gather more information until only one microbe remains and all others have been eliminated as possibilities. Thus

Place each substance carefully on the surface of agar‚ carefully noting which is which so that the crystals are spread equally over the agar and not too close to the edge of the dish. Measure the diameter of the colored area immediately after adding the substance to the agar with regular 10-minute

of LB agar. We then put 250 µn of CaCl2 transformation solution into two micro test tubes for the purpose of changing the bacterium’s cell wall to allow the pGLO plasmid to enter more easily. Second‚ we placed one colony of E. Coli from our original plate into each of the micro test tubes. Subsequently‚ we extracted a loopful of pGLO plasmid with a sterile loop and then placed it in one of the micro test tubes. We incubated the tubes on the ice for ten minutes while we prepared four new agar plates

(positive). The catalase test result indicated that my unknown was negative because no bubbles formed when I placed a loop of the organism into hydrogen peroxide. The next step was to examine a blood agar plate to examine the colonial morphology of hemolysis ‚ my organism produced gamma hemolysis on the blood agar because there was no hemolysis on the plate after 48 hours incubation period. After examining my unknown for hemolysis I set a series of five experiments: Bacitracin SX CAMP Enterococcosel
