title: Selective Recovery of 16S rRNA Sequences from Natural Microbial Communities in the Form of cDNA.
abstract: Cloning of cDNA obtained from 16S rRNA (16S rcDNA) selectively retrieves species-specific sequence information useful for analyzing the composition and structure of natural microbial communities. With this technique we obtained recombinant 16S rcDNA libraries from Escherichia coli and from a model hot-spring cyanobacterial-mat community. The recombinant plasmids contained exclusively 16S rRNA-derived inserts. This selective approach is independent of biasing culture techniques and eliminates the laborious screening required to locate 16S rRNA gene-bearing recombinants in genomic DNA libraries obtained from natural communities.
