| Salinity, other physico-chemical parameters and anthropogenic pollution are the main factors affecting bacterial communities in estuaries. We estimated the impact of these parameters on the distribution of bacterial communities in the Adour estuary (France), a moderately Polluted water body characterized by short residence times of particles and water and absence of a maximum turbidity zone. Eight stations were established along the salinity gradient from freshwater to marine conditions. For the 3 typical estuarine stations (water mixing zone), samples were collected at both low and high tide and at different depths according to the position of the halocline. This sampling strategy generated 35 samples with different degrees of mixing between fresh water... |

| Numeration, biomass, distribution within time, some physiological characters and a taxonomical outline, with a standardized micro method, of aerobic hétérotrophie bacteria isolated from sediments an waters, from fishponds of "Domaine de Certes" (Arcachon) from june 1977 to may 1978 are described. Number of hétérotrophie bacteria evolved in a significant way, according to seasons, and bacterial biomass is higher in the sediments than in the waters. Metabolic or physiological differences (proteolysis, denitrification) appeared among populations due to the origin of sediments. Moreover the qualitative study pointed out taxonomical units as Bacillus associated to seasons, or Agrobacterium associated to vegetable detritical sediments. |
