BACKGROUND/AIM The purpose of the present investigation was to examine subgingival microbial profiles associated with refractory periodontitis and to seek such profiles in periodontally healthy, periodontally well-maintained elder and untreated periodontitis subjects. METHODS 36 subjects were defined as refractory on the basis of further attachment loss after scaling and root planing, surgery...

Aim: To analyse the microbial profile of canine persistent wound infections. Materials and Methods: The total wound samples (n=172) taken from both traumatic (140) and post-surgical (32) persistent wounds in canines were processed for routine microbial isolation and identification during a period of 15 months. Results: Staphylococcus intermedius was found to be the predominant isolate from all ...

BACKGROUND Kiwifruit is high in pectic polysaccharides and dietary fiber. This study aimed to find out how the ingestion of kiwifruit will affect intestinal microbiota populations, namely Lactobacillus, Bacteroides, Clostridium, Bifidobacterium, and Enterococcus. METHODS Freeze dried kiwifruit (equivalent of two fresh kiwifruits) was given to each of the six subjects daily for four days. Faec...

Microbial activity in produced water from hydraulic fracturing operations can lead to undesired environmental impacts and increase gas production costs. However, the metabolic profile of these microbial communities is not well understood. Here, for the first time, we present results from a shotgun metagenome of microbial communities in both hydraulic fracturing source water and wastewater produ...

Relatively little is known about the microbial communities adapted to soil environments contaminated with aged complex hydrocarbon mixtures, especially in the subsurface soil layers. In this work we studied the microbial communities in two different soil profiles down to the depth of 7 m which originated from a 30-year-old site contaminated with petroleum hydrocarbons (PHCs) and from a clean si...

The sustainable recovery of resources from wastewater streams can provide many social and environmental benefits. A common strategy to recover valuable resources from wastewater is to harness the products of fermentation by complex microbial communities. In these fermentation bioreactors high microbial community diversity within the inoculum source is commonly assumed as sufficient for the sele...

Characterization of community-level substrate utilization via incubation of environmental samples in BIOLOG microplates has been increasingly applied in many areas of microbial ecology. The easily-produced multivariate profile allows for intensive spatial and temporal analysis of microbial communities, and it is a sensitive and reproducible tool for characterizing microbial communities. This wo...
