| The purpose of this study is to evaluate the behaviour of the bacterial flora of a macrotidal estuary, originating from different sources: the Elorn freshwater river, a sewage treatment plant (STP), and the sediment. Viable counts were done using severa} culture media in order to determine where bacteria originated. Principal component analysis showed that the estuary was subjected to two well-defined conditions. On the one band, during periods of low turbulence (neap tide), resuspension of bottom sediments did not occur. Bacterial flora decreased from the upper reaches of the estuary to its lower part, coming mainly from two sources (river and STP). As a function of salinity variations, bacterial flora showed a progressive increase of the endogeneous... |
