Sensitive Detection of 2-MIB and Geosmin in Drinking Water.
Identification and functional analysis of genes controlling biosynthesis of 2-methylisoborneol. 2-MIB and geosmin originally isolated from actinomycetes were determined by Gerber (18, 19) and Medsker et al. (20). Geosmin is a degraded sesquiterpenoid alcohol, and biochemical and molec-.MIB and Geosmin are naturally occurring terpene alcohols which can be produced by blue green algae (Cyanobacteria) and filamentous bacteria (Actinomycetes). Although these organic compounds are usually only present at ultra-trace levels, the human nose can detect Geosmin at concentrations.Geosmin and 2-MIB testing in drinking water was established. Therefore, the requirement for a rapid, high sensitivity and reliable analysis method of trace off-odor levels is of special significance to the efficient control regional drinking water.
Papers by Keyword: Geosmin.. Abstract: The different pretreatment methods for analysis of geosmin and 2-methylisobomeol by GC-MS in drinking water were systemically studied and applied, such as liquid-liquid extraction, solid phase extraction, and solid phase micro-extraction.. 2-MIB and geosmin both fell below the odor threshold, which.Geosmin and 2-MIB were extracted from water samples by solid phase micro-extraction (SPME) and analysis was carried out using gas chromatography-mass spectrometry (GC-MS). Results from the analysis demonstrated that these polymers were highly effective in removing geosmin and 2-MIB.
In this study, a simple headspace solid phase microextraction procedure (HSPME) was developed and applied successfully to the qualitative and quantitative analysis of source water and drinking.
