Sediments were stored at 4°C for approximately 3 weeks prior to analysis.
Frequency of a given RFLP type out of 100 total clones.
Closest identified match in the GenBank database followed by percent similarity.
The sequence of clone S-J147 did not appear to be chimeric; however, it did not significantly match anything in the GenBank database, cultured or uncultured. Portions of the gene shared significant similarity with that of Thermoleiphilum minutum, but across the entire gene similarity was only 76%.
