| bio-enhanced activated carbon filter with immobilized microorganisms for removing organic pollutants in the songhua river. | five dominant microorganisms including four kinds of pseudomonas and one kind of bacillus were isolated from the songhua river. the organic pollutants removal potential and community composition of these five dominant microorganisms immobilized on activated carbon filter, which is called the bio-enhanced activated carbon filter (beac), were investigated to compare with the naturally formed biological activated carbon (bac) filter. songhua river was used as the raw water. the pilot scale test res ... | 2010 | 21123911 |
| removal of methylmercury and tributyltin (tbt) using marine microorganisms. | two marine species of bacteria were isolated that are capable of degrading organometallic contaminants: pseudomonas balearica, which decomposes methylmercury; and shewanella putrefaciens, which decomposes tributyltin. p. balearica decomposed 97% of methylmercury (20.0 μg/l) into inorganic mercury after 3 h, while s. putrefaciens decomposed 88% of tributyltin (55.3 μg sn/l) in real wastewater after 36 h. these data indicate that the two bacteria efficiently decomposed the targeted substances and ... | 2012 | 22212416 |
| engineering pseudomonas protegens pf-5 for nitrogen fixation and its application to improve plant growth under nitrogen-deficient conditions. | nitrogen is the second most critical factor for crop production after water. in this study, the beneficial rhizobacterium pseudomonas protegens pf-5 was genetically modified to fix nitrogen using the genes encoding the nitrogenase of pseudomonas stutzeri a1501 via the x940 cosmid. pf-5 x940 was able to grow in l medium without nitrogen, displayed high nitrogenase activity and released significant quantities of ammonium to the medium. pf-5 x940 also showed constitutive expression and enzymatic ac ... | 2013 | 23675499 |
