About a century ago, researchers first recognized a connection between the activity of environmental microorganisms and cases of anaerobic iron corrosion. Since then, such microbially influenced corrosion (MIC) has gained prominence and its technical and economic implications are now widely recognized. Under anoxic conditions (e.g., in oil and gas pipelines), sulfate-reducing bacteria (SRB) are...

The kinetics for the reduction of sulfate alone and for concurrent uranium [U(VI)] and sulfate reduction, by mixed and pure cultures of sulfate-reducing bacteria (SRB) at 21 +/- 3 degrees C were studied. The mixed culture contained the SRB Desulfovibrio vulgaris along with a Clostridium sp. determined via 16S ribosomal DNA analysis. The pure culture was Desulfovibrio desulfuricans (ATCC 7757). ...

Sulfate-reducing bacteria (SRB) represent a group of prokaryotic microorganisms that are widely spread in the anoxic environment (seabed, riverbed and lakebed sediments, mud, intestinal tract humans animals, metal surfaces). SRB species also have an impact on processes occurring including connections between their presence inflammatory bowel disease (IBD). Since these can develop antimicrobial ...

Introduction. Sansevieria liberica Gerome and Labroy (Agavaceae) is a perennial plant widely distributed in tropical Africa. Preparations of the plant are commonly used across Nigeria for the treatment of inflammatory conditions. Based on the fact that herbal medicine is a strong component of integrative medicine, this study was conducted to evaluate the anticancer activity of root extracts of ...

In the search for novel cytotoxic agents, sesquiterpenoids and phenylpropanoids have provided interesting lead compounds. From the chloroform extract of the underground parts of Laserpitium latifolium, the daucane sesquiterpenoids laserpitin and acetyldesoxodehydrolaserpitin, and the phenylpropanoids laserin and latifolon were isolated as the major compounds. Acetyldesoxodehydrolaserpitin is id...

A Solar Radio Burst (SRB) is one of the most severe natural hazards affecting performance global navigation satellite systems (GNSS). Considering influence different threat factors, GNSS developers upgrade to amend accuracy and noise-proof features systems. In particular, GPS gradually replaces “old” satellites (GPS IIA, IIR-A, IIR-B) with new-generation equipment IIR-M, IIF, III) featured by a...

McCrea and colleagues (2005) sought to evaluate the efficacy of a multidimensional assessment approach to the management of concussion in contact sport in their article entitled “Standard regression-based methods for measuring recovery after sport-related concussion.” They used the Standardized Regression-Based (SRB) method to determine when an athlete was recovered. Though not in the above art...

Sulfate-reducing bacteria (SRB) are a group of microbes that use sulfate (SO4 ) as a final electron acceptor instead of oxygen for respiration (Al-Zuhair, El-Naas et al. 2008). SRB are able to use a very wide spectrum of different low molecular organic compounds (e.g. lactate, acetate, proprionate, succinate, pyruvate, ethanol, sugars, etc.) for growth, with SO4 being reduced to hydrogen sulfid...

The interaction among financial and precious metals in various markets is a furthermost interesting matter for investors. fluctuation prices one market may influence the price index of other market. Gold have widespread economic effects on different activities. These are directly specious all decisions adopted by This study aims to check whether bank stock return (SRB) insurance (SRI) significa...

Biocorrosion, also known as microbiologically influenced corrosion (MIC), is caused by various corrosive biofilms. So far, laboratory experimental MIC pitting tests in the published literature have overwhelmingly focused on sulfate reducing bacteria (SRB) that use sulfate as the terminal electron acceptor because SRB and sulfate are often found at anaerobic pitting sites. Many laboratory pure-c...
