Introduction In my report I will discuss what I did as an experiment and what I hope for it to achieve. Firstly I carried out an experiment to assay the effectiveness that a range of disinfectants have on the growth of ecoli and whether or not it can prevent it from growing. From the experiment i should be able to see that some disinfectants have a greater effect than others do. From this I shall then draw a conclusion and evaluation on what was the most effective‚ and could there have been any

Unawareness of Dietary Supplements Over the years body image has changed and people have come to strenuous methods to keep up with the media on how they should look. The idea of adding or having something added to your body is not always something positive. This is the picture dietary supplements paint. “A dietary supplement can come in a capsule‚ a pill‚ or even liquid form; these pills or liquids include a dietary ingredient such as vitamins‚ minerals‚ herb botanical‚ amino acids or

microorganisms. Gain more knowledge about selective media and differential media. Practice use of the catalase test‚ coagulase and the oxidase test. Observe microbial flora of the nose. Significance: Understand the use of Mannitol salt agar‚ blood agar and MacConkey agar plates which must be used based on the components of the bacteria. The catalase test will be used to understand the difference in facultative anaerobic and groam positive from aero tolerant anaerobes. The coagulase test converts fibrogen

CHAPTER ONE 1.0 INTRODUCTION Natural rubber is produced by over 2000 plants species and its main constituent is poly (cis-I‚4-isoprene).a highly unsaturated hydrocarbon. Since 1914 there have been efforts to investigate microbial rubber degradation: However‚ only recently have the first proteins involved in this process have been identified and characterized and have the corresponding genes cloned. Analysis of the degradation product of natural rubber and synthetic rubbers isolated from various

controlled variable is important in order to be able to look at what the bacteria would look like if it hadn’t been contaminated and just left as agar. Having a sample of agar that wasnt exposed to any bacteria will provide a clear picutre of what grew on the agar upon feeding bacteria to it. 2. Why shoudn’t a student swab his or her mouth or cough onto an agar plate to initiate a culture? Even though most bacteria in the human body is harmless‚ if one was knowingly or unknowingly ill then harmful

bacteria uses citrate as a source of carbon‚ Simmon’s citrate agar was used as the medium on which the bacteria was grown. The Simmon’s citrate agar consists of sodium citrate as the source of carbon‚ ammonium dihydrogen phosphate as the source of nitrogen along with pH indicator such as bromothymol blue. Procedure: The Citratase activity was detected by inoculating the unknown bacteria on the slant surface of Simmon’s citrate agar. Followed by overnight incubation at 37°C. Day after the slant

_____________________________________________________________________________ Agarose is a polymeric cross-linked polysaccharide extracted from the seaweed agar. Agarose is used widely in gel electrophoresis because it gels at a lower temperature‚ does not contain the inhibitors of virus growth frequently present in agar‚ and has more uniform pore size than that of agar. It is also easily poured and does not denature the samples. In agarose gel electrophoresis‚ DNA or RNA fragments are separated or isolated according

(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

Materials: The materials we used in this lab were a petri dish with agar‚ forceps‚ water‚ alcohol‚ hydrogen peroxide‚ antibacterial soap‚ filter paper disc‚ tape‚ and a permanent marker. Procedure: We started this lab on May 12‚ 2014. Using a permanent marker on the bottom of the dish‚ we divided it into 4 sections.
