Results In this experiment we used paper chromatography to determine the amount of chlorophyll a‚ chlorophyll b‚ xanthophyll‚ and beta-carotene in a tube of blended leaf extract. We recorded our findings on the table labeled table 1. Table 1 shows the transmittance at each wavelength on a table from 400 to 720. The information on Figure 1 came from the leaf extract on the paper chromatography that we used; with the help of acetone we saw the spectrum and the differences of the different pigments

The results for nitrate were inconclusive‚ there are traces of nitrate in wells 15‚ 20‚ 23‚ and 21 but we couldn’t find the source. We believe that number 15 is the source but there is very little amount of pollutants in the water to make the solution turn black. Wells 15‚ 20‚ 23‚ and 21 when tested for nitrates‚ the iodine changed to a yellowish blackish color. The hypothesis was not supported‚ well number 26 did not test positive for any of the pollutants. The first well tested was well number

RESULTS AND DISCUSSION In the Iron (II) - Silver Ions System the reaction had a balance chemical equation of Fe2+ + Ag+ Fe3+ + Ag(S). The process if centrifugation is used in this part of the experiment to be able to separate the supernatant and the precipitate. And the supernatant will be used to test for the presence of Fe2+‚ Ag+ and Fe3+ in the solution. Results showed that there is a positive presence for FE 2+‚ Fe3+ and Ag+ because of the visible change of color of Prussian blue precipitate

From my first batch of results‚ Proteus vulgaris reared its head and I had it figured out‚ but needed the second half to prove my hypothesis correct. It was in fact my discovery that led to the class announcement that the Gelatinase test results for Proteus vulgaris

In food it is common to use Nisin at levels depending on the food type regulatory approval. Nisin cannot be produced chemically therefore it has to be synthesised using fermentation. During fermentation various stages of growth occur and as a result different conditions can occur during this fermentation process‚ eg pH‚ most organisms produce acid as they grow and therefore in the Lag phase ( a period of adptation for the cells to their new environment‚ new enzymes are synthesized) and in
