The amount of bacteriain the control sample increased over the duration of the test Also, the percentage of 0.01 and 0.03 upward trend, 0.06 and 0.09 after a slight decline and the percentages of 0.12, 0.15, 0.3, 0.45% have been reduced since the beginning of the experiment and before the 18th day they reached zero.
