Comparative sequence analysis of a 16S rRNA gene clone library from
the chemocline of the meromictic Lake Cadagno (Switzerland) revealed
the presence of a diverse number of phototrophic sulfur bacteria.
Sequences resembled those of rRNA of type strains Chromatium okenii DSM169 and Amoebobacter purpureus DSM4197, as
well as those of four bacteria forming a tight cluster with A. purpureus DSM4197 and Lamprocystis roseopersicina
DSM229. In situ hybridization with fluorescent (Cy3 labeled)
oligonucleotide probes indicated that all large-celled phototrophic
sulfur bacteria in the chemocline of Lake Cadagno were represented by
C. okenii DSM169, while small-celled phototrophic sulfur
bacteria consisted of four major populations with different
distribution profiles in the chemocline indicating different
ecophysiological adaptations.
