an aquifer located within a petroleum processing plant in moín, costa rica, suffers hydrocarbon pollution. this study aimed to determine the ability of indigenous microorganisms from this site to degrade polycyclic aromatic hydrocarbons (pahs) to evaluate the feasibility of an eventual bioremediation process. aerobic conditions were found in the aquifer, while microbial analyses of the groundwa...

Coeliac disease (CD) is associated with alterations of the intestinal microbiota. Although several Bifidobacterium strains showed anti-inflammatory activity and prevention of toxic gliadin peptides generation in vitro, few data are available on their efficacy when administered to CD subjects. This study evaluated the effect of administration for three months of a food supplement based on two Bi...

Article history: Received on: 06/06/2013 Revised on: 27/06/2013 Accepted on: 14/08/2013 Available online: 18/09/2013 This review summarizes about the actinomycetes and their capability to produce bioactive secondary metabolites, many of which have been successfully isolated and turned into useful drugs and other organic chemicals. Microbial pathogens are becoming increasingly resistant to avail...

When ingested in sufficient numbers, probiotics are expected to confer one or more proven health benefits on the consumer. Theoretically, the effectiveness of a probiotic food product is the sum of its microbial quality and its functional potential. Whereas the latter may vary much with the body (target) site, delivery mode, human target population, and health benefit envisaged microbial assess...

Propolis, a natural product elaborated by bees, determines a wide variety of therapeutic actions because of its bioactive compounds. Our researches were focused on evaluating the anti-pathogenic effect of eight ethanolic propolis extracts (EEP) from different Romanian regions on 11 Staphylococcus sp. clinical strains. The content of flavons, flavonols and polyphenols was investigated by spectro...

Synthetic polymers are widely used in daily life. Due to increasing environmental concerns related to global warming and the depletion of oil reserves, the development of microbial-based fermentation processes for the production of polymer building block chemicals from renewable resources is desirable to replace current petroleum-based methods. To this end, strains that efficiently produce the ...

Mono-cultured or mixed-cultured fermentations have been preferred to spontaneous fermentation in pickle production. Therefore, five different groups of garlic pickles were produced adopting the Turkish-style using monocultures mixed-cultures containing four probiotic strains. The inhibitory effect on those strains, antagonistic activities, organic acid production abilities strains examined. che...

Strains of bacteria with the ability utilizing glyphosate as sole source carbon were isolated from soil exposed to herbicide by culture enrichment method and identified through partial 16S rRNA gene sequence analysis. Sixteen different microbial strains glyphosate-contaminated sites in Kubau local govt. area, Kaduna state. Two strains: BBDD3 BBD4 found be best degraders able withstand up 16.4 m...

Microbial biofilms that form on metallic surfaces in natural seawater are known to generate efficient oxygen-reducing cathodes. The microbial catalysis of oxygen reduction is a major mechanism of corrosion in marine aerobic environments; it can also be exploited to develop biocathodes for microbial fuel cells. In the latter case, seawater biocathodes have the great advantage of operating in hig...

PURPOSE The aim of this study was to identify in vitro antimicrobial activity of the tissue conditioner containing silver nanoparticles on microbial strains, Staphylococcus aureus, Streptococcus mutans and Candida albicans. MATERIALS AND METHODS Experimental disc samples (20.0×3.0 mm) of tissue conditioner (GC Soft-Liner, GC cooperation, Tokyo, Japan) containing 0.1 - 3.0% silver nanoparticle...
