Vertical dynamics of bacteria in a tropical tidal river
Bacteria play a very important in controlling mineralization of organic matter. Therefore, river ecosystem is greatly influenced by bacterial dynamics. A study was conducted to vertical dynamics of bacterial in the Kuantan River which is influenced by daily tidal activity. For this study water sampl...
