Abstract
Mangroves are complex ecosystems that contribute the coast environment by maintaining
terrestrial and marine food chains, among others. Black mangrove, Avicennia germinans, on
which this study is centered, predominates in hot climates and in soils with salinities that exceed
40 parts per thousand. An analysis of the diversity of halophilic/ halotolerant microorganisms
present in the soil of these mangroves at two different localities in the southwest area of Puerto
Rico, the Solar Salterns of Cabo Rojo and the Boquerón National Forest, was carried out using
culture-dependent and culture-independent techniques. Soil samples from six different trees from
each locality and at three different depths (0, 10 and 20cm) were processed. Analyses of isolates
indicate the presence of halophilic/halotolerant microorganisms from the Proteobacteria and
Firmicutes phyla. Environmental gene libraries showed that most of the clones obtained were
affiliated to the Proteobacteria and Bacteroidetes phyla.
