Etude de la biomasse bactérienne dans le bassin de Marennes-Oléron

A seasonal study of total microflore shows that heterotrophic germs are submitted to a distinctive evolution in autumn and winter suspension and degradation of detritic material; in spring an summer bacterial growth due to degradation of phytoplanction. In summer enterocoques give evidence of positive summer pollution. Survival on the mud of Escherichia coli and overall of enterocoques indicates that the substration is particularly suitable to germ proliferation;
