Sažetak
We investigated the effect of a sewage primary treatment on the bacterial community structure in the waste waters and the impact of their release on the marine environment by combining microbiological, chemical and molecular tools. The study was performed in the town of Rovinj (northeastern Adriatic coast), a typical urban Mediterranean area where untreated or primary treated waters are released in the sea. The results have shown that the primary treatment did not affect substantially the bacterial community structure and did not reduce the concentration of potentially pathogenic bacteria, coprostanol and fecal indicator bacteria. The distribution of the sewage plume in the sea was governed by the vertical stratification and the currents. The rate of bacterial biomass production depended on environmental conditions while bacterial abundance and replication rates were increased in the most polluted waters. In these waters the bacterial community was characterized by the presence of allochthonous bacteria belonging to Epsilonproteobacteria, Firmicutes, Gammaproteobacteria and Bacteroidetes. The latter two taxa were also present in the unpolluted waters but with a different structure that included marine autochthonous members typical for oligotrophic environments (gammaproteobacterial SAR86 clade, OM60 [NOR5] clade and bacteroidetes NS4 and NS5 marine groups, respectively). In addition, the alphaproteobacterial SAR11 clade and the AEGEAN-169 marine group were always abundant only in the unpolluted waters while other groups appeared seasonally. Although the overall impact of sewage waters on the receiving marine environment was limited, a high sanitary risk persisted due to the presence of a relevant proportion of potentially pathogenic bacteria.
