Fidelity ofThermococcus litoralisDNA polymerase (VentTM) in PCR determined by denaturing gradient gel electrophoresis

Association of Streptomyces community composition determined by PCR-denaturing gradient gel electrophoresis with indoor mold status.

Both Streptomyces species and mold species have previously been isolated from moisture-damaged building materials; however, an association between these two groups of microorganisms in indoor environments is not clear. In this study, we used a culture-independent method, PCR-denaturing gradient gel electrophoresis (PCR-DGGE), to investigate the composition of the Streptomyces community in house...

Bacterial population dynamics in a reverse-osmosis water purification system determined by fluorescent staining and PCR-denaturing gradient gel electrophoresis.

The bacterial population dynamics in an industrial scale reverse-osmosis (RO) water purification system were analyzed by fluorescent staining methods and denaturing gradient gel electrophoresis (DGGE). Bacterial numbers increased with storage in a tank, and bacterial diversity changed during the water purification process. A DNA sequence-based analysis of the major bands on the DGGE gel reveale...

Bifidobacterial diversity in human feces detected by genus-specific PCR and denaturing gradient gel electrophoresis.

We describe the development and validation of a method for the qualitative analysis of complex bifidobacterial communities based on PCR and denaturing gradient gel electrophoresis (DGGE). Bifidobacterium genus-specific primers were used to amplify an approximately 520-bp fragment from the 16S ribosomal DNA (rDNA), and the fragments were separated in a sequence-specific manner in DGGE. PCR produ...

Identification and population dynamics of yeasts in sourdough fermentation processes by PCR-denaturing gradient gel electrophoresis.

Four sourdoughs (A to D) were produced under practical conditions, using a starter obtained from a mixture of three commercially available sourdough starters and baker's yeast. The doughs were continuously propagated until the composition of the microbiota remained stable. A fungi-specific PCR-denaturing gradient gel electrophoresis (DGGE) system was established to monitor the development of th...
