| new degenerate cytophaga-flexibacter-bacteroides-specific 16s ribosomal dna-targeted oligonucleotide probes reveal high bacterial diversity in river taff epilithon. | river microbial communities play an important role in global nutrient cycles, and aggregated bacteria such as those in epilithic biofilms may be major contributors. in this study the bacterial diversity of river taff epilithon in south wales was investigated. a 16s ribosomal dna (rdna) clone library was constructed and analyzed by partial sequencing of 76 of 347 clones and hybridization with taxon-specific probes. the epilithon was found to be very diverse, with an estimated 59.6% of the bacteri ... | 2002 | 11772628 |
