Abstract

The diversity of deep-sea cultivable bacteria was studied in seven sediment samples of the Colombian Caribbean. Three hundred and fifty two marine bacteria were isolated according to its distinct morphological character on the solid media, then DNA sequences of the 16S rRNA were amplified to identify the isolated strains. The identified bacterial were arranged in three phylogenetic groups, Firmicutes, Proteobacteria, and Actinobacteria, with 34 different OTUs defined at >= 97% of similarity and 70 OTUs at >= 98.65%, being the 51% Firmicutes, 34% Proteobacteria and 15% Actinobacteria. Bacillus and Fictibacillus were the dominant genera in Firmicutes, Halomonas and Pseudomonas in Proteobacteria and Streptomyces and Micromonospora in Actinobacteria. In addition, the strains were tested for biosurfactants and lipolytic enzymes production, with 120 biosurfactant producing strains (mainly Firmicutes) and, 56 lipolytic enzymes producing strains (Proteobacteria). This report contributes to the understanding of the diversity of the marine deep-sea cultivable bacteria from the Colombian Caribbean, and their potential application as bioremediation agents. (AU)
