Staphylococci were isolated from rural and urban populations in Iraq, which were not known to be exposed to either heavy metals or antibiotics. The antibiotic and heavy metal resistance patterns of these strains were analyzed in both mannitol-fermenting and nonfermenting strains. Over 90% of the strains were resistant to at least one of the following antibiotics: penicillin, chloramphenicol, er...
Many bacteria in the environment have adapted to the presence of toxic heavy metals. Over the last 30 years, this heavy metal tolerance was the subject of extensive research. The bacterium Cupriavidus metallidurans strain CH34, originally isolated by us in 1976 from a metal processing factory, is considered a major model organism in this field because it withstands milli-molar range concentrati...
Present study investigated the antibiotic resistance profile of bacterial strains isolated from soil, sediment and waters of Eloor-Edayar Industrial belt of Kerala, South India. A total of 165 bacterial strains were isolated and tested for their sensitivity to 11 common antibiotics (Ampicillin, Erythromycin, Gentamycin, Nalidixic acid, Penicillin, Vancomycin, Novobiocin, Amikacin, Kanamycin, St...
Prosopis juliflora is characterized by distinct and profuse growth even in nutritionally poor soil and environmentally stressed conditions and is believed to harbor some novel heavy metal-resistant bacteria in the rhizosphere and endosphere. This study was performed to isolate and characterize Cr-resistant bacteria from the rhizosphere and endosphere of P. juliflora growing on the tannery efflu...
BACKGROUND Heavy metals naturally occur in the marine environment and ecosystems. Due to anthropogenic influence they became common waters and coastal regions pollutants in particular where their concentrations remain hazardously high. We therefore tested a protocol for combined analysis of 6 heavy metal (Pb, Cd, Cr, Zn, Fe and Hg) concentrations in mussels Mytilus galloprovincialis collected f...
The present work demonstrates the heavy metal resistance and detoxification of Cr(VI) by the probiotic actinobacterial cultures isolated from chicken and goat feces. The actinobacterial isolates were screened for heavy metal resistance by qualitative, semiquantitative assays and Cr(VI) biosorption was determined by analytical techniques such as atomic absorption spectrophotometry and Fourier tr...
Cupriavidus sp. HMR-1 was isolated from a heavy metal-enriched culture of activated sludge from a wastewater treatment plant in Hong Kong. Here, we release the HMR-1 genome to provide basic genetic characteristics for a better understanding of its multiple heavy metal resistance properties.
Serratia marcescens S2I7 is a heavy metal-resistant, polyaromatic hydrocarbon-degrading bacterium isolated from petroleum-contaminated sites. The genome contains one circular chromosome (5,241,555 bp; GC content 60.1%) with 4,533 coding sequences. The draft genome sequence includes specific genetic elements for degradation of hydrocarbons and for heavy metal resistance.
