The Effect of Barley Straw on the Growth of Cynobacteria

In our experiment we investigated the effect of barley straw on the growth of cynobacteria. We accomplished this by running an experiment with a control and test group. At the beginning of our experiment we placed a set amount of cynobacteria into each group. Barley straw was added to the test group while nothing was added to the control group. Throughout the experiment, oxygen, carbon dioxide and several water quality tests were performed every three days for six weeks. With the results from all of the tests, we were able to conclude that that barley straw did not have an effect on the growth of cynobacteria.
