| functional gene expression of oil-degrading bacteria resistant to hexadecane toxicity. | contamination with oil poses a threat to the environment and to human health worldwide. biological methodologies have proved to be economical, versatile and efficient for the remediation of pollutants. in this paper, a highly efficient oil-degrading bacterial strain ustb-2 was isolated from an oil production well of dagang oil field in tianjin, china. the 16s rrna sequence of ustb-2 showed 100% similarity with that of bacillus subtilis bsn5. hexadecane is one of the most important components in ... | 2013 | 23972733 |
| occurrence of sulfonamide and tetracycline-resistant bacteria and resistance genes in aquaculture environment. | the occurrence of sulfonamide and tetracycline resistance and their pollution profile in the aquaculture environment of tianjin, northern china, were investigated. the presence of antibiotic-resistant bacteria was identified and the corresponding antibiotic resistance genes (args) were quantified at 6 aquaculture farms in tianjin. sulfonamide-resistance genes were prevalent and their concentrations were the highest detected (3.0 × 10(-5) to 3.3 × 10(-4) for sul1/16s rdna, 2.0 × 10(-4) to 1.8 × 1 ... | 2012 | 22377146 |
