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...

A denaturing gradient gel electrophoresis (DGGE) method is described that detects even single base pair changes in mitochondrial DNA (mtDNA). In this method, restriction fragments of mtDNA are electrophoresed in a urea/formamide gradient gel at 60 degrees C. Migration distance of each mtDNA fragment in the gel depends on melting behavior which reflects base composition. Fragments are located by...

Haria , a rice fermented alcoholic beverage, is prepared and consumed by the vast number of Indian tribal people as staple drink. Lactic acid bacteria are dominant microbial community in this beverage. Participating lactic bacterial diversity beverage were determined using PCR denaturing gradient gel electrophoresis (PCR-DGGE) Lactobacillus plantarum, brevis, Lysinibacillus sp., fusiformis grou...

Here, we report on the spatial and temporal variation in sulphate-reducing bacterial community structure and activity in three hypersaline coastal pans. Community structure was determined using denaturing gradient gel electrophoresis (DGGE). Cluster analysis of DGGE patterns indicated that similar microbial populations were generally found in individual pans but varied from one pan to the other...

Fresh herbs such as basil constitute an important food commodity worldwide. Basil provides considerable culinary and health benefits, but has also been implicated in foodborne illnesses. The naturally occurring bacterial community on basil leaves is currently unknown, so the epiphytic bacterial community was investigated using the culture-independent techniques denaturing gradient gel electroph...

Rice is a staple food for over half of the world’s population, and fungal spoilage in stored rice may occur when moisture content temperature are conducive. Aspergillus sp. Penicillium most harmful toxigenic species that produce mycotoxins. Molds pose potential threat to public health cause huge economic loss. Therefore, it great importance find out how molds multiply rice. This study focused o...
