Co-contamination of antibiotics and heavy metals prevails in the environment, and may play an important role in disseminating bacterial antibiotic resistance, but the selective effects of heavy metals on bacterial antibiotic resistance is largely unclear. To investigate this, the effects of heavy metals on antibiotic resistance were studied in a genome-sequenced bacterium, LSJC7. The results sh...
The effect of cadmium and mercuric chlorides on some physiological traits in two cultivars of wheat.
One of the important abiotic stresses that negatively affect cereals such as wheat is heavy metals. Soil pollution with heavy metals has become one of the major environmental concerns resulting from the industrial development and use of fertilizers containing heavy metals. One way to counteract the negative effects of heavy metals in plants which produce reactive oxygen species is the activatio...
in this study, it was aimed to determine the effects of ship dismantling zones on distribution ofheavy metal resistance and level of antibiotic resistance of bacterial isolates from eastern aegean sea coast.thirteen isolates were identified by phylogenetic analysis using 16s rdna sequences which indicated that theisolates belonged to genus bacillus. these strains were investigated in respect of...

Removal of heavy metals from wastewater needs advance chemical technology and is more expensive too. The cheaper alternative for this is the bioremediation using heavy metals resistant microorganisms. In this study, 10 heavy metal resistant bacteria were isolated from oxidation ditch of wastewater treatment plant of Bagmati Area Sewerage Project. These include chromium resistant Staphylococcus ...
The sustainability and non-biodegradability of heavy metals, on the one hand, and the increasing environmental pollution caused by industrial wastewater on the other hand have increased the attention to heavy metal remediation. Cyanobacteria are one of the most important agents of heavy metals removal in drought and aquatic environments. Their ability to remove metals is related to various mech...
in this research we have studied the effect of some transition-metals (cu, ag and au) substitutions on two-electron reduction potential of flavins by application of dft method. all geometries have been optimized at blyp level of theory and “6-31+g** + lanl2dz” mixed basis set. the frequency job at the same method and basis sets has been performed to obtain gibbs free energy of compounds. it h...
A total of 94 bacteria, associated with wild Achanthobrama marmid (Heckel, 1843) in Sir Dam lake of Turkey identified. Subsequently selected isolates were characterized and identified to the genus level The 94 members of Enterobacteriaceae were isolated in the gills and intestines, and among the isolates, E. coli were represented at a rate of 55%, Shigella spp. at a rate of 21%, Salmonella spp....
recreational waters should be considered as risks for enterococcal infections in regions with high utilization and long exposure periods. the aim of this study was to investigate the resistance of enterococci to selected antibiotics and some heavy metals [pb+2, fe+2, zn+2 and cr+2]. a total of 75 enterococcal isolates was obtained from 54 bathing and fishing water samples from 9 bathing and fis...
