phenol and its homologues are aromatics containing hydroxyl, methyl, amide and sulphonic groups attached to the benzene ring. these molecules are both anthropogenic and xenobiotics. phenols are environmental pollutants discharged through wastewaters from various industries. phenols are toxic to several biochemical reactions. however biological transformation of phenols to non-toxic entities exi...

background: amoxicillin is widely used as an antibiotic in the modern medicine. due to its chemical structure, polarity, activity level, antibiotic specifications, and environmental sustainability, amoxicillin leaks into the groundwater, surface waters, and drinking water wells. many physical and chemical methods have been suggested for removing amoxicillin from aquatic environments. however, t...

The low number and activity of hydrocarbon-degrading bacteria and the low solubility and availability of hydrocarbons hamper bioremediation of oil-contaminated soils in arid deserts, thus bioremediation treatments that circumvent these limitations are required. We tested the effect of Ethylenediaminetetraacetic acid (EDTA) addition, at different concentrations (i.e. 0.1, 1 and 10 mM), on bacter...

Biodegradation of pollutants in the environment is directly affected by microbial communities and pollutant mixture at site. Lab experiments using bacterial consortia substrate mixtures are required to increase our understanding these processes environment. One deficiencies working with environmental cultures inability culture identify active strains while knowing they representative original I...

The FimA protein of Streptococcus parasanguis is a virulence factor in the rat model of endocarditis, and immunization with FimA protects rats against homologous bacterial challenge. Because FimA-like proteins are widespread among the oral streptococci, the leading cause of native valve endocarditis, we evaluated the ability of this vaccinogen to protect rats when challenged by other streptococ...
