Abstract

The ecological changes are the main problem of post tin mining activities, such as post tin mining ponds and it has occurred for a long time chronosequence. The understanding of how post tin mining activities bring ecological changes and how the microorganism communities respond to these environment changes becomes an important part to explore the potential of bioremediator to accelerate the recovery of water quality as water sources for secondary activities and habitable for organisms and further, to determine the next aquatic ecosystem management. The change of ecological factors such as pH, dissolved oxygen (DO), and heavy metals can be focused for a discussion as affecting factors for changes in microorganism communities. In fact, all of the three factors can drive the alteration of microecosystem and indirectly causes change in microorganism communities. However, the survival capability of microorganisms, resistance and resilience capacity, and the interaction of microorganisms with ecosystem change, in particular, in post tin mining ponds chronosequence has not been explained properly.
