SUSTC/30 August 2013



It seemed that god was fond of playing jokes on us and good things should be pairs. After continuous defeats, we got continuous success now. The experiments done yesterday was a big success as well. The red fluorescence given by the 5m M nitrate bacteria was apparent even on the daylight. The outcome turned to be excellent, and other plates had good conditions as well.

Then we prepared 40% glycerol, and preserved all types of the bacteria we got. Since the preliminary experiment on the nitrate was a huge success, we decided to do the concentration gradient experiment. We cultured the bacteria in different nitrate concentration-0m M, 5m M, 10 m M, 15m M, 20m M.
