Abstract
Phylogenetic divergence among sulfate-reducing bateria in an estuarine sediment sample was investigated by PCR amplification and comparison of partial 16S rDNA sequences. Twenty unique 16S rDNA sequences were found, 12 from delta subclass bacteria based on overall sequence similarity (82-91%). Two successive PCR amplifications were used to obtain and clone the 16S rDNA. The first reaction used templates derived from phosphate-buffered saline washed sediment with primers designed to amplify nearly full-length bacterial domain 16S rDNA. A produce from a first reaction was used as template in a second reaction with primers designed to selectivity amplify a region of 16S rDNA genes of sulfate-reducing bacteria. A phylogenetic tree incorporating the cloned sequences suggests the presence of yet to be cultivated lines of sulfate-reducing bacteria within the sediment sample.
