| Summary: | 碩士 === 元培醫事科技大學 === 食品科學研究所 === 103 === E. coli (Escherichia coli) bacteria as indicators of water quality monitoring, water quality of representation if there E.coli contamination. In this study, the use of membrane filtration (Membrane filter method) and changes in the metabolism of E. coli specific conductivity of chemical signals detected E. coli spring water. The results show that the detection range of 103～108 CFU / mL, R2 is 0.9868, repeated detection of 106 CFU / mL, with good reproducibility, with an average of 3.13 ± 0.30 hours with an electrochemical method using a membrane filtration method can be low sample was concentrated achieve rapid detection. Display, electrochemical method has the potential to develop into a fast and stable quality of E. coli testing.
