英文摘要 | Occurrences of odorous bacterial metabolites, 2-methylisoborneol (MIB) and geosmin (GSM), in drinking water supply reservoirs are considered as a nuisance by the water industry and a source of complaints from customers. In Eagle Creek Reservoir, routine monitoring programs of MIB and GSM highlight intense odorous outbreaks during the spring season when high inflow discharges occur. Cyanobacteria have always been assumed to be source of these metabolites even if no known producers are present in raw water. A copper-based algaecide is often used to terminate the metabolite production and the algal growth in the reservoir. The current study was designed to investigate and identify other biological sources involved in the biosynthesis of MIB and GSM metabolites as well as environmental factors that could be important triggers for the growth of bacterial producers. The community structure of the bacterioplankton was determined using a 16S rRNA gene sequencing technique, which showed that not only Cyanobacteria but Actinobacteria also were involved in the reservoir internal production. Planktothrix species was identified as the main source of GSM (p < 0.001) while Streptomyces (Actinobacteria) was very likely responsible of MIB (p < 0.01). Application of an algaecide disrupted GSM and the growth of Planktothrix but was less effective against MIB and Streptomyces. Statistical analyses revealed that MIB- and GSM-causing bacteria were found abundant when the water was enriched with nitrogen, temperature cooler, and the water column mixed. |
