The microbial diversity of biofilms formed on the surfaces of amalgam, glass-ionomer cement, and resin composite was analyzed by denaturing gradient gel electrophoresis (DGGE). The V2-V3 region of salivary microbial 16S rDNA gene sequences of planktonic and biofilm bacteria, after 1 day and 1 week of incubation, was amplified by polymerase chain reaction (PCR) and analyzed by DGGE. The amounts ...
In noninteracting isolated quantum systems out of equilibrium, local subsystems typically relax to nonthermal stationary states. the standard framework, information on rest system is discarded, and such states are described by a generalized Gibbs ensemble (GGE), maximizing entropy while respecting constraints imposed conservation laws. Here we show that latter also completely characterize recen...

Effectively and accurately assessing total microbial community diversity is one of the primary challenges in modern microbial ecology. This is particularly true with regard to the detection and characterization of unculturable populations and those present only in low abundance. We report a novel strategy, GC fractionation combined with denaturing gradient gel electrophoresis (GC-DGGE), which c...
As it is currently often not know how anaerobic bioreactors, e.g. for biogas production, react if the substrate is contaminated by toxic compounds like antibiotics. This study evaluated how anaerobic sequencing batch reactors were affected by amendments of different antibiotics and stepwise increasing concentrations. The compositions of microbial community were determined in the seed sludge usi...
Using bromodeoxyuridine (BrdU) magnetic beads immunocapture and a PCR-denaturing gradient gel electrophoresis (DGGE) technique (BUMP-DGGE), we determined seasonal variations in the community structures of actively growing bacteria in the neritic waters of Hiroshima Bay, western Japan. The community structures of actively growing bacteria were separated into two clusters, corresponding to the ti...
We investigated the structure of bacterial communities present in livestock manure-based composting processes and evaluated the bacterial succession during the composting processes. Compost samples were derived separately from swine manure, dairy manure and sewage sludge. The structure of the bacterial community was analyzed by polymerase chain reaction-denaturing gradient gel electrophoresis (...
Aerobic granular sludge constitutes a novel technology for wastewater treatment. This study focused on the effect of 2-fluorophenol (2-FP) shock loadings on the microbial community diversity present in aerobic granules before and after inoculation with a bacterial strain able to degrade 2-FP, Rhodococcus sp. strain FP1. After bioaugmentation, apart from strain FP1, five culturable bacteria were...
Familial defective apolipoprotein (apo) B-100 (FDB), a condition that may give rise to hypercholesterolemia, is caused by mutations around codon 3500 of the apo B gene. We have compared the ability of three molecular-scanning techniques, heteroduplex analysis, single-strand conformation polymorphism (SSCP) analysis, and denaturing gradient gel electrophoresis (DGGE), to detect these mutations i...
The distribution of mucosa-associated bacteria, bifidobacteria and lactobacilli and closely related lactic acid bacteria, in biopsy samples from the ascending, transverse, and descending parts of the colon from four individuals was investigated by denaturing gradient gel electrophoresis (DGGE). Bifidobacterial genus-specific, Lactobacillus group-specific, and universal bacterial primers were us...
