The primary objective of this study was to investigate the relation between the presence of geosmin in water and the bacterial community structure within the granular activated carbon (GAC) system of water treatment plants(WTPs) in South Korea. Dissolved organic carbon (DOC) and geosmin were analyzed before and after GAC treatment. Geosmin was found in raw water from S and K WTPs. Interestingly but not surprisingly, 16S rRNA clone library indicated that the bacterial communities from S and K WTPs GAC systems were closely related to geosmin-degrading bacteria. Based on the result of phylogenetic tree and multidimensional scaling (MDS) plot, bacterial clones from GAC under the influence of geosmin were clustered with Variovorax paradoxus DB 9b and Comamonas sp. DB mg. In other words, the presence of geosmin in water might have inevitably contributed to the growth of geosmin-degraders within the respective GAC system. |
