Fish and AgNor-mapping of the 45S and 5S rRNA genes in wild and cultivated Capsicum species (Solananceae)
(National Research Council Canada-NRC Research Press, 2016-02)
Chromosome number and position of rDNA were studied in 12 wild and cultivated species of the genus Capsicum with chromosome numbers x = 12 and x = 13 (22 samples). For the first time in these species, the 5S and 45S rRNA ...
Molecular monitoring of microbial diversity in an UASB reactor
(Elsevier, 2003-07)
The dynamics of the microbial community structure of a full-scale upflow anaerobic sludge blanket reactor has been analyzed using culture-independent 16S rRNA-based methods. During the start-up of the process, denaturing ...
Phylogenetic distribution and evolutionary pattern of an alfa-proteobacterial small RNA gene that controls polyhydroxybutyrate accumulation in Sinorhizobium meliloti
(Academic Press Inc Elsevier Science, 2016-03)
It has become clear that sRNAs play relevant regulatory functions in bacteria. However, a comprehensive understanding of their biological roles considering evolutionary aspects has not been achieved for most of them. Thus, ...
Power analysis for real-time PCR quantification of genes in activated sludge and analysis of the variability introduced by DNA extraction
(American Society for Microbiology, 2003-11)
The aims of this study were to determine the power of discrimination of the real-time PCR assay for monitoring fluctuations in microbial populations within activated sludge and to identify sample processing points where ...
16S rRNA gene amplicon dataset of prokaryotic communities from a subantarctic marine ecosystem: Ushuaia Bay and surrounding waters
(Elsevier Inc, 2020-10)
We provide a 16S rRNA gene dataset of prokaryotic assemblages of a subantarctic marine ecosystem. Samples were collected at 2 stations (one near Ushuaia Bay and the other close to Bridges islands in the Beagle Channel). ...
Regulation of polyhydroxybutyrate accumulation in Sinorhizobium meliloti by the trans-encoded small RNA MmgR
(American Society for Microbiology, 2017-01)
Riboregulation has a major role in the fine-tuning of multiple bacterial processes. Among the RNA players, trans-encoded untranslated small RNAs (sRNAs) regulate complex metabolic networks by tuning expression from multiple ...
Feasibility of using RFLP of PCR-amplified 16S rRNA gene(s) for rapid differentiation of isolates of aerobic spore-forming bacteria from honey
(Elsevier Science, 2019-10)
This study aimed to assess the feasibility of using RFLP of PCR-amplified 16S rRNA gene (s) by using universalprimers 27f/1492r and a combination of three restriction enzymes, AluI, CfoI, and TaqI, for a low-cost, rapidscreen ...
Bacterial taxa abundance pattern in an industrial wastewater treatment system determined by the full rRNA cycle approach
(Wiley Blackwell Publishing, Inc, 2007-07)
The description of the diversity and structure of microbial communities through quantification of the constituent populations is one of the major objectives in environmental microbiology. The implications of models for ...
16S rRNA gene diversity in ancient gray and pink salt from san simón salt mines in Tarija, Bolivia
(American Society for Microbiology, 2020-10-08)
DNA from 250 million-year-old pink and gray salts from mines in Tarija, Bolivia, subjected to 16S rRNA gene amplicon sequencing and analysis provided evidence for similar but distinct prokaryotic communities. The results ...
Microbial abundance and community composition in biofilms on in-pipe sensors in a drinking water distribution system
(Elsevier, 2020-09)
Collecting biofilm samples from drinking water distribution systems (DWDSs) is challenging due to limited access to the pipes during regular operations. We report here the analysis of microbial communities in biofilm and ...
