A comparison of random sequence reads versus 16S rDNA sequences for estimating the biodiversity of a metagenomic library

The construction of metagenomic libraries has permitted the study of microorganisms resistant to isolation and the analysis of 16S rDNA sequences has been used for over two decades to examine bacterial biodiversity. Here, we show that the analysis of random sequence reads (RSRs) instead of 16S is a suitable shortcut to estimate the biodiversity of a bacterial community from metagenomic libraries. We generated 10,010 RSRs from a metagenomic library of microorganisms found in human faecal samples. Then searched them using the program BLASTN against a prokaryotic sequence database to assign a taxon to each RSR. The results were compared with those obtained by screening and analysing the clones containing 16S rDNA sequences in the whole library. We found that the biodiversity observed by RSR analysis is consistent with that obtained by 16S rDNA. We also show that RSRs are suitable to compare the biodiversity between different metagenomic libraries. RSRs can thus provide a good estimate of the biodiversity of a metagenomic library and, as an alternative to 16S, this approach is both faster and cheaper.

Is a Combined School/Public Library Right for Your Community?

This document is intended to assist Iowa communities in making informed decisions on combining school and public library services. It provides decision-makers with a means of assessing the feasibility of establishing a combined library and, if the decision is made to proceed, with a Planning Guide that addresses the many areas of library operations that need to be considered if the combined library is to be successful. Alternatives to combining libraries exist. Contracted services provide one such option. There are many areas where school and public libraries can and should collaborate in order to provide better service to the community. These alternatives are also outlined in this document.
