As the training progressed, as aerobic bacteria and other anaerobic bacteria such as sulfate-reducing bacteria, the role of methane-producing bacteria, consumption of organic acids, so that the pH showed a rising trend.

As for training, as a result of aerobic bacteria and other Anaerobic bacteria such as sulfate-reducing bacteria, producing methane Bacteria consume the role pH organic acid, thereby showing a rising trend.

Along with raise march, because the good oxygen fungus as well as other anaerobe like sulfate return to original state fungus, produces the methane fungus the function, consumption organic acid, thus causes the tendency which pH presents increases unceasingly.

Along with the training, due to aerobic bacteria and other sulfate-reducing bacteria, anaerobic bacteria, such as methanogens, consume the organic acids, so that the pH increasing trend.
