  abstract = {{A}ctivity of heterotrophic bacteria is recognized as an important process governing the biochemical functioning of many aquatic ecosystems. {T}he aim of this study is to compare bacterial isolates of pelagic heterotrophic bacteria from two sites, each with a different trophic status (4 microg/l at {K}pass and 23 microg/l at {L}ayo for chlorophyll index) located in the {E}bri{\'e} lagoon, and the bacteria associated with periphyton growing on an artificial reef of bamboos stuck into the sediment of the two sites. {H}ierarchical classifications were performed from morphological and biochemical tests of 343 heterotrophic bacterial strains isolated from the two sites and for each habitat. {D}espite differences in trophic status, numerical taxonomic analysis of the pelagic bacterial strains (n = 165) showed a dominant cluster (72% of strains) of mixed origin (close to 50% of isolates from each site). {T}he majority of these strains were non-fermentative rods producing neither amino-acids decarboxylases, nor acid from any carbohydrates. {I}n the more eutrophic site ({L}ayo), few differences of properties were observed between pelagic and periphyton-associated bacteria. {O}n the contrary, a large part of bacteria isolated from bamboo at {K}pass was characterized by specific particularities such as the degradation of arginine, tryptophan and citrate. {N}umerical taxonomic analysis allowed the distinguishing of specific characteristics of bacteria according to the habitat. {O}ur results suggest that hydrological and biological conditions (especially photosynthetic exudates from periphyton) may induce an obvious specialization of the periphytic bacteria in the less eutrophic ecosystem ({K}pass) compared to the bacteria isolated from the more eutrophic environment ({L}ayo).
