Distribution of viable aerobic heterotrophic bacteria, total number of microorganisms alpha-, beta-, delta- and omega- proteobacteria in the eastern coastal zone of Havana and in oceanic waters southwest of Cuba
It was determined the distribution of viable heterotrophic bacteria, Phylum proteobacteria and the total number of microorganisms in a coastal sector east of Havana and in oceanic waters southwest of Cuba. Samplings were carried out in September 2005 and May 2006. In general, the concentration of microorganisms was higher in the coastal zone; although in the SW of the Exclusive Economic Zone (EEZ), high values were found mainly in stations closest to the shelf, where there is an exchange between nutrient enriched waters from the Gulf of Batabano and the adjacent oligotrophic oceanic waters, and in areas characterized by complex water mass dynamics. In most stations, proteobacteria was the highest contributor to the total number of microorganisms. It was observed that the total average concentration of proteobacteria was 1.5 times higher in the coastal area in relation to that in oceanic waters southwest of Cuba, where the α-proteobacteria predominated, while the other subclasses were represented by lower percentages.
