Analysing the effect of industrial and urban polluted zones on microbial diversity in the SaiGon -DongNai river system (Vietnam) by Thi Tuyet Nga Nguyen( )

The SaiGon-DongNai (SG-DN)river system is the most important major water source for all twelve Southern Vietnam cities and provinces and is now dramatically polluted by industrial and living activities, giving “a threat” to the lives of millions people sharing this water source. The Ministry of Natural Resources and Environment of Vietnam reported that the rivers received around 1.54 billion liters of waste water from 70 industrial parks per day, including 35 percent of untreated medical waste, and tests since 2006 have found pollution in this river has increased to “serious levels”, an especially high concentration of organic toxic substances. Until now, there is no data on the microbial diversity in SG-DN river system especially in the sediments, where most of the microbial biomass is generally located. The sediment samples were collected in 13 locations across the rivers representing warning polluted locations done by Mr. Nguyen Thanh Hung of the National Water Qualifying in SG-DN river system. In order to characterize the microbial populations present at our chosen sites, the total DNA from the environmental samples were extracted and amplified at the V3 to V1 regions of the 16S rDNA. The study revealed that microbial population changed from upstream to downstream at the phylum, genus and OTUs levels after running through the industrial and dense population zone. Moreover, the canals of the SG-DN river catchment are heavily polluted with high concentrations of organic compounds (PAHs) and possessed different bacterial communities compared to the samples from the rivers
