HIGHLIGHTING OF SOME PHYSIOLOGICAL BACTERIAL GROUPS ISOLATED FROM DANUBE DELTA BIOSPHERE RESERVE, AREA ROŞU, ROŞULEŢ AND PUIU LAKES
Journal Title: Current Trends in Natural Sciences - Year 2017, Vol 6, Issue 11
Industrialization and the socio-economic conditions, as well as the human standards changing from the last few decades, led to increased pollution degree including the discharge area of he Danube River in the Black Sea.Therefore it becomes essential the ecosystems assessment, in order to know their status. In this case the evaluation can be made also by studying the area microbiota. In this study it was followed main bacterial groups from Roşu, Roşuleţ and Puiu lakes, part of the Danube Delta Biosphere Reservation, located in the proximity of the Sulina harbor. Our researches indicated the presence of some microbial groups, like the anaerobic heterotrophic bacteria, anaerobic facultative bacteria, heterotrophic aerobic bacteria, denitrifying bacteria and sulfate-reducing bacteria. These microorganisms, presents both in the water mass and in the benthic layer, of the investigated area, are not only statistical references, but a potential indicator strains and tests sources for laboratory biotechnological experimental level of the potential of these microorganisms.
