Abstract: Limitations of traditional techniques based on selective enrichment and pure culture isolation make it difficult to precisely characterize the natural microbial ecosystems. Molecular techniques are now being developed and used to address these limitations. Group specific 16SrRNAs targeted oligonucleotide probes of different phylogenetic levels are increasingly used to identify and quantify the microbial members in complex environmental samples. Two domain specific probes were used in this study to elementarily characterize the defined mixtures of RNAs extracted from pure culture (synthetic samples) and a RNAsample obtained from landfill leachate (environmental sample). The results demonstrated that 16SrRNAquantitative hybridization provided an excellent estimation of domain level community composition of these samples, and thus, had a huge potential of usefulness in microbial ecology studies.
