Última 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.

Metabolic potentialities of bacterial communities in marine water after Crude Oil pollution (Arabian Light) and in marine water after pollution and treatment (enrichment: Inipol EAP 22) have been studied and compared. With data analysis: regressions, hierarchical ascending classification and multifactor correspondence analysis, the treatment gives rise to conservation and one increase of enzymatic pool (second day) of the bacterial sample as a combined metabolic homogeneity contrary to pollution impact. The direct assimilation of hydrocarbons looks more regular and slow without treatment.
