conclusions p. aeruginosa and s. marcescens can be good candidates for the detoxification of cr (vi) in soltan abad river. results the results indicated that pseudomonas aeruginosa and serratia marcescens were the most resistant bacteria with mics of 200 and 150 mg/l, respectively. both bacteria completely reduced 25 and 50 mg/l of cr (vi) in 36 hours and 48 hours, respectively. the growth rate...

use of microorganisms for removing mercury is an effective technology for the treatment of industrial wastewaters and can become an effective tool for the remediation of man-impacted coastal ecosystems with this metal. in this study, seven types of mercury resistant bacteria were separated from industrial waste and minimum inhibitory concentration (mic), were determined for these bacteria. resu...

conclusions according to the results, six strains were resistant to six or seven antibiotics and all strains were at least resistant to two antibiotics. however, for each of these resistant bacteria one bacteriophage was isolated from environmental samples, which showed the effectiveness of bacteriophages to remove clinically resistant e. coli strains. effective phages in vitro showed effective...

the effects of dietary supplementation of garlic (allium sativum)extract on the growth and disease resistance of african catfish, clarias gariepinus was evaluated. also in-vitro evaluation of susceptibility of fish-borne multidrug resistant (mdr) pathogenic bacteria to aqueous extract of garlic was done. aqueous garlic extract exhibited inhibitory activity against mdr bacteria and the degree of...

sheep adapted to consume tannins rich feeds such as oak leaf (ol) appear to develop defensive mechanisms by their ruminal bacteria against these polyphenols. the capabilities of ruminal isolated tannins resistant bacteria from these animals to ferment a tanniniferous feed (i.e., pistachio hulls, (ph) which were incubated with rumen fluid from holstein dairy cows was assessed. six g positive coc...
