    the 2 tests: the glass tube setup and the water agar-gel setup. In the glass tube setup‚ two cotton balls were soaked in the solutions of hydrochloric acid (HCl) and ammonium hydroxide (NH4OH) and were simultaneously placed on both ends of the tubing.NH4OH had a lighter molecular weight of 35 g/mole which diffused at a faster rate of 24.8 cm and formed a white smoke near the HCl end that had the molecular weight of 36 g/mole. The water agar-gel setup was made up of a petri dish containing

    the glass tube test and the agar-water gel test. In the glass tube set-up‚ two cotton plugs soaked in two different substances (HCl and NH4OH) were inserted into the two ends of the glass tube. The substance with the lighter molecular weight value (NH4OH‚ M = 35.0459 g/mole) diffused at a faster rate (dAve = 25.8cm)‚ resulting in the formation of a white ring around the glass closer to the side of the heavier substance (HCl‚ M = 36.4611 g/mole; dAve = 10.8 cm). The agar-water gel set up was composed

    for specific organisms. For i.e. Mackonkey agar only grows on gran(-). If a sample is negative it grows and if it is positive it doesn’t grow. Last but not least Differential media relies on color change of the media itself. This color change highlights the bacteria if it has a specific trait. For i.e. If sugar ferments there will be a color change. III. Reagents: 1.Tryptone 2.Yeast extract 3.NaCl 4.KCl 5.MgCl2 6. MgSO4 7.Glucose/ Dextrose 8.H20 9.Agar( for solid) IV.

    General Purpose media is designed to grow most organisms and do not contain growth inhibitors. Standard Methods Agar and Blood Agar Bases are examples of general purpose media. Differential Media Differential media contain a component that allow an observable change when a specific chemical reaction takes place. Simmons Citrate Agar is an example of a differential medium. In Simmons Citrate Agar‚ there is a pH indicator that turns from green to blue when citrate is utilized as the sole carbon source

    Lab 11 Methodology By using aseptic‚ a little cultured bacteria was inoculated on the TSA agar. A quadric streak was making. Inoculation loop was heated and keep it cold for a while before the next quadratic streak. Six agar plates were observed for 24 hour at temperature of 30ºC. Choose one from the dense colony and make a sub-culture on the new agar plate. The step was repeated to get a single colony‚ which is pure colony. a) Sequestration of bacteria from fish organs Methodology
