Diversity of anoxygenic phototrophic sulfur bacteria in the microbial mats of the Ebro Delta: a combined morphological and molecular approach.

The diversity of purple and green sulfur bacteria in the multilayered sediments of the Ebro Delta was investigated. Specific oligonucleotide primers for these groups were used for the selective amplification of 16S rRNA gene sequences. Subsequently, amplification products were separated by denaturing gradient gel electrophoresis and sequenced, which yielded a total of 32 sequences. Six of the sequences were related to different cultivated members of the green sulfur bacteria assemblage, whereas seven fell into the cluster of marine or halophilic Chromatiaceae. Six sequences were clustered with the family Ectothiorhodospiraceae, three of the six being closely related to chemotrophic bacteria grouped together with Halorhodospira genus, and the other three forming a group related to the genus Ectothiorhodospira. The last thirteen sequences constituted a cluster where no molecular isolate from microbial mats has so far been reported. Our results indicate that the natural diversity in the ecosystem studied has been significantly underestimated in the past and point out the presence of novel species not related to all known purple sulfur bacteria. Furthermore, the detection of green sulfur bacteria, after only an initial step of enrichment, suggests that -- with the appropriate methodology -- several genera, such as Prosthecochloris, could be established as regular members of marine microbial mats.[1]
