Última Etude experimentale de la disparition de coliformes fecaux d'un effluent urb ain en milieu marin ArchiMer Bonnefont, J; Lelong, P; Martin, Y. The authors studied survival of faecal coliform (decrease rate + T90) in experimental devices (closed or continuous flow systems) using various dilutions of urban sewage in sea-water. Survival appears to be high (T90 between 12 to 81 h). Dilution level of sewage and organic matter contents seems to be important to explain the decrease of faecal coliforms observed in these experiments.

Ano: 1984 URL: http://archimer.ifremer.fr/doc/1984/acte-1009.pdf Interactions entre les bacteries et les algues dans une culture continue de phytoplancton naturel soumise aux conditions exterieures ArchiMer Gauthier, M; Martin, Y; Lelong, P; Breittmayer, V. During an experimental continuous culture of natural marine phytoplankton in environmental conditions, microbial and biochemical tests performed to study production of antibacterial and antialgal substances by unicellular algae. Some parameters were further monitored to characterize bacteria and phytoplankton growth. The presence of inhibitors of algal origin was studied both in the water and in the algal biomass at different phases of the culture, through bioassays performed with bacteria (marine pseudomonads and vibrios, and telluric strains) and several algal strains. Interpretation of the results is difficult. Two successive phases appeared during the growth of phytoplankton, with two different algal populations. The unsteady population of phase I was...

Ano: 1984 URL: http://archimer.ifremer.fr/doc/1984/acte-984.pdf Models of relations between bacteria and plankton, and regeneration processes in marine planktonic ecosystem. ArchiMer Martin, Y; Lelong, P; Cauchi, B. In order to study bacteria-plankton relationships, experimental and mathematical models were used to stimulate biological processes implicated in plankton ecosystems and to analyze community relationships. The model components are phytoplankton, zooplankton, autotrophic and heterotrophic bacteria, ciliates, nutrients, organic matter and phytoplankton antibiotics. This study shows the importance of some factors affecting bacteria communities dynamics and the bacterial activity in mineralization process. Bacterial populations seem to be controlled essentially by the concentration and chemical composition of organic substrates. Antibiosis and predation show a lesser importance on changes in bacteria communities.
