We performed multiple tests on our unknown culture‚ therefore we are very confident that it is correctly identified. We identified that K. pneumoniae is a facultative anaerobe. When inoculated onto an agar slant‚ K. pneumoniae took the shape of echinulate. When inoculated onto a nutrient agar plate‚ we identified that the growth of K. pneumoniae was round and smooth with a convex elevation.

(Penicillin and Erthomycin)‚ then we would see the antibiotics stop the growth of bacteria around a certain area in the agar dish. This is because antibiotics are used to stop the growth and kill bacteria . DISCUSSI ON A fter completing the experiment and recording the results‚ the data was inconclusive. The results were not accurate to what should have occurred within the agar dishes. The results were recorded showed that E. coli had no effect from both antibiotics as the bacteria still grew. The

Another experiment was performed with the use of petri dish containing an agar-water gel with three wells. One drop of each substance (potassium dichromate‚ potassium permanganate‚ and methylene blue) was placed on each respective well. In three-minute interval for 30 minutes‚ potassium permanganate‚ which has the lowest molecular
