introduction because of population growth, human needs to produce raw materials have increased. different industries have developed that discharge pollutants into the environment. one type of the contaminants is heavy metals that are abundant in municipal and industrial waste waters. these compounds aren’t capable of biological degradation and in certain quantities are considered toxic to many ...

Rhizobacteria may enhance biomass production and heavy metal tolerance of plants under stress conditions. The present study was carried out for isolation of metal-resistant bacteria that can be further utilized for phytoremediation process. A potential metal-resistant strain CRB15 was isolated from rhizospheric region of Saccharum spontaneum that was found to be resistant against Cu (6.29 mM), ...

Display of peptides on the surface of bacteria offers many new and exciting applications in biotechnology. Fimbriae is a good candidate for epitope display on the surface of bacteria. The potential of CS3 fimbriae of enterotoxigenic E. coli as a display system has been investigated. A novel cell surface display system with metal binding property was developed by using CS3 fimbriae. Short metal ...

Cladophora and Enteromorpha are the filamentous green-algal genuses that have a widespread distribution in Caspian Sea Coast. The aim of this study was to assess the antimicrobial activities of Cladophora and Enteromorpha in South of Caspian Sea. Antibacterial activities of hydroalcoholic extracts of five different gram negative and positive bacteria including Staphylococcus aureus, Bacillus su...

In the last few years, many efforts have been devoted to investigating antibacterial activity of metal nanoparticles, especially against multidrug-resistant bacteria. Recently extensively drug-resistant (XDR) bacteria emerged and caused a global threat. The purpose this manuscript was synthesize nanostructured γ-Al2O3 as an agent some XDRs. results showed that Al2O3 mix rod spherical shapes in ...

objectives in this study, we explored a physical method of converting drug-resistant bacteria to drug-sensitive ones. materials and methods this is an in vitro case-control study, performed at the ionizing and non-ionizing radiation protection research center (inirprc), shiraz university of medical sciences (sums), shiraz, iran in 2014. all experiments were carried out using gram-negative bacte...

This study focuses on identifying relationships between the content of heavy metals in water and resistance patterns different bacteria. Samples from watercourses one most important mining areas Mexico were collected. Seventy-one bacteria isolated, their to Cr, Zn, Cu, Ag, Hg, Co was studied. The Minimum Inhibitory Concentration range determined, a Multiple Metal Resistant index calculated. Aft...
