Simultaneous in situ visualization of seven distinct bacterial genotypes,
all affiliated with the phylogenetically narrow group of beta-1
Proteobacteria, was achieved in activated sludge. This finding indicates
that the high diversity found in the same sample by direct rRNA sequence
retrieval was indeed present in this complex community. By the combination
of comparative rRNA sequence analysis, in situ hybridization with
fluorescently labeled, rRNA-targeted oligonucleotides and confocal laser
scanning microscopy several microbial populations can be analyzed for
abundance, relative spatial distribution and phylogeny directly at their
site of action without prior cultivation.
