Quantitative Comparisons of 16S rRNA Gene Sequence Libraries from Environmental Samples

Quantitative comparisons of 16S rRNA gene sequence libraries from environmental samples.

To determine the significance of differences between clonal libraries of environmental rRNA gene sequences, differences between homologous coverage curves, CX(D), and heterologous coverage curves, CXY(D), were calculated by a Cramér-von Mises-type statistic and compared by a Monte Carlo test procedure. This method successfully distinguished rRNA gene sequence libraries from soil and bioreactors...

Flow cytometry-assisted cloning of specific sequence motifs from complex 16S rRNA gene libraries.

A flow cytometry method was developed for rapid screening and recovery of cloned DNA containing common sequence motifs. This approach, termed fluorescence-activated cell sorting-assisted cloning, was used to recover sequences affiliated with a unique lineage within the Bacteroidetes not abundant in a clone library of environmental 16S rRNA genes.

Molecular Identification of the Persian Gulf Sea Hare (Aplysia sp.) Based on 16s rRNA Gene Sequence

Background: Sea hares of the Aplysia genus are among the mollusks of interest for various researchers to study their phylogeny, bioactive compounds and the nervous system. These mollusks are herbivorous and produce chemical compounds (ink) to defend themselves. The present study provided molecular identification of the Persian Gulf (Bushehr city) sea hare using 16s rRNA gene sequence. Materials...

Streamlined method to analyze 16S rRNA gene clone libraries.

Identification of Comamonas species using 16S rRNA gene sequence

A bacterial strain Bz02 was isolated from a water sample collected from river Gomti at the Indian city of Lucknow. We characterized the strain using 16S rRNA sequence. Phylogenetic analysis showed that the strain formed a monophyletic clade with members of the genus Comamonas. The closest phylogenetic relative was Comamonas testosteroni with 95% 16S rRNA gene sequence similarity. It is proposed...
