- aggregation abstract "Monitoring the hygienic quality of drinking waters by determining the concentration of fecal indicators with traditional plate count techniques suffers from important drawbacks. In this work, the potential of PCR-DGGE (polymerase chain reaction - denaturing gradient gel electrophoresis) analysis of 16S rDNA genes to fingerprint the bacterial populations of mineral water and groundwater was investigated. A rapid and simple pretreatment to concentrate and release bacterial DNA prior to PCR was explored. This pretreatment was successful for commercially bottled mineral water. For groundwater, an additional resuscitation step was required to obtain a PCR signal. It was clear that the groundwater under scrutiny contained a more diverse bacterial community than the mineral water. A comparison was made between four kinds of mineral waters and one sample of groundwater using the developed procedures. For each kind of water, bacterial populations cultured on R2A plates were also subjected to PCR-DGGE. Comparison of the fingerprints of the plated samples and the original samples suggested the presence of viable but nonculturable bacteria in the waters. The obtained cluster dendrogram indicated that each kind of water was characterized by a specific molecular fingerprint. The sensitivity of the whole of the procedure was between 10(4) and 10(5) cfu ml(-1) as determined using a pure culture of Escherichia coli. The described PCR-DGGE method can constitute the basis of a new and interesting strategy to monitor in a relatively rapid way (less than 24 h) the bacterial quality of waters such as mineral water, groundwater and certain types of reclaimed water.".
