The aim of this work has been to analyze the effects of a bioemulsificant exopolysaccharide (EPS2003) on the abundance and vitality of natural marine microbial population. Harbor seawater microcosms, supplemented with bioemulsificant EPS2003 (at different concentrations), were monitored over 20 days. The microbial community dynamic was analyzed by measurement of bacterial density (total and cultivable count) and vitality (live/dead count and total RNA amount). The results obtained show that addition of bioemulsificant (also at different concentrations), as sole carbon source, supported growth of the indigenous bacterial populations and revealed that this substance is optimal for use in the participations of recovery of environment polluted from oil. In comparison, an analysis with commercial dispersant was also carried out.
