Approach to determine the diversity of Legionella species by nested PCR-DGGE in aquatic environments. [PDF]

open access: yesPLoS ONE, 2017
In this study, we describe a nested PCR-DGGE strategy to detect Legionella communities from river water samples. The nearly full-length 16S rRNA gene was amplified using bacterial primer in the first step.

Evaluation of variations in plastid DNA non-coding regions in selected species of the genus Solanum

open access: yesCzech Journal of Genetics and Plant Breeding, 2017
The diversity of three non-coding plastid DNA loci (trnL/trnF spacer, trnV/16SrRNA spacer, trnL/trnL intron) was assessed in 16 Solanum L. species (135 individuals).

Improved PCR-DGGE analysis by emulsion-PCR for the determination of food geographical origin: A case study on Greek PDO “avgotaracho Mesolonghiou”

open access: yesCurrent Research in Food Science, 2021
Greek avgotaracho Mesolonghiou (fish eggs from Flathead Mullet) is a highly valuable food product which holds Protected Destination of Origin status. The aim of this work was to use PCR-DGGE technique to examine whether there is a correlation between ...

Approaches for diversity analysis of cultivable and non-cultivable bacteriain real soil

open access: yesPlant, Soil and Environment, 2009
Until recently, investigators had no idea how accurately cultivated microorganisms represented the overall microbial diversity. The cultivation-dependent approach is limited by the fact that the overwhelming majority of microorganisms present in soil ...

Effect of Different Inoculum Combination on Biohydrogen Production from Melon Fruit Waste

open access: yesInternational Journal of Renewable Energy Development, 2018
The natural microbial consortium from many sources widely used for hydrogen production. Type of substrate and operating conditions applied on the biodigesters of the natural consortium used as inoculum impact the variation of species and number of ...

Fingerprinting sequence variation in ribosomal DNA of parasites by DGGE [PDF]

open access: yesMolecular and Cellular Probes, 1996
Although there is a tendency for rDNA genes within a species to maintain sequence homogeneity, there can be significant levels of variation among rDNA repeat sequences within populations or individuals of a species as a consequence of mutation mechanisms.

Emulsion PCR (ePCR) as a Tool to Improve the Power of DGGE Analysis for Microbial Population Studies

open access: yesMicroorganisms, 2020
To the authors’ knowledge, this is the first report of the use of emulsion-Polymerase chain reaction (e-PCR) coupled with denaturing gradient gel electrophoresis (DGGE) analysis. In the present work the effectiveness of ePCR in improving the power of the

Testing of primers for the study of cyanobacterial molecular diversity by DGGE [PDF]

open access: yesJournal of Microbiological Methods, 2006
Denaturing Gradient Gel electrophoresis (DGGE) is a PCR-based technique which is widely used in the study of microbial communities. Here, the use of the three specific 16S rRNA cyanobacterial specific primers CYA359F, CYA781R(a) and CYA781R(b) on the assessment of the molecular diversity of cyanobacterial communities is examined.
