The abundance and diversity of cyanobacteria living in sediments collected from six vents, (temperature range 37 - 130°C), close to the Panarea Island (Italy) were studied. The diversity of cyanobacteria was analyzed by using a PCR-DGGE approach with group-specific primers. The greatest number and diversity of cyanobacteria were registered at the coldest vent. Sequencing of DGGE fragments revealed that most sequences matched with uncultured cyanobacteria deposited in databases and some were distantly affiliated with different species of Synechococcus. New, genetically distant ribotypes of cyanobacteria are the dominant oxygenic phototrophs in shallow hydrothermal system of Panarea Island.

Abstract

The abundance and diversity of cyanobacteria living in sediments collected from six vents, (temperature range 37 - 130°C), close to the Panarea Island (Italy) were studied. The diversity of cyanobacteria was analyzed by using a PCR-DGGE approach with group-specific primers. The greatest number and diversity of cyanobacteria were registered at the coldest vent. Sequencing of DGGE fragments revealed that most sequences matched with uncultured cyanobacteria deposited in databases and some were distantly affiliated with different species of Synechococcus. New, genetically distant ribotypes of cyanobacteria are the dominant oxygenic phototrophs in shallow hydrothermal system of Panarea Island.
