Heavy metal contamination in the environment due to anthropogenic activities in industrial and agricultural areas represents stress for the living ecosystem including soil microorganisms. The adaptive response of bacterial communities to these pollutants can be observed through the increasing proportion of resistant bacteria.

Heat shock proteins (Hsps), also known as stress proteins, are expressed by living organisms. Hsp genes play key roles in the regulation of change in response to various abiotic stresses (e.g., salinity, drought, heavy metal, and extreme temperatures). In our previous studies, all Hsp family gene members were determined and named using bioinformatics approaches. We also examined their expression profiles under different stress conditions.

Ferrous iron (Fe) and zinc (Zn) at high concentration in the soil cause heavy metal toxicity and greatly affect rice yield and quality. To improve rice production, understanding the genetic and molecular resistance mechanisms to excess Fe and Zn in rice is essential. Genome-wide association study (GWAS) is an effective way to identify loci and favorable alleles governing Fe and Zn toxicty as well as dissect the genetic relationship between them in a genetically diverse population.

The aim of this study is to determine the antimicrobial resistance profile patterns to 15 antibiotics and heavy metals (Zn+2, Cu+2 and Cd+2) by Pantoeaagglomerans bacteria. The (MIC) of the heavy metals was varied from 200 µg /mL to 2200 µg/mL. The results showed that the bacteria were resistant to Zn+2, Cu+2 and Cd+2, considering the MIC values compared with the strain Escherichia coli K-12 used as control. P.

This article presents a study of the bacteria bioremediation characters and their heavy metal and antibiotic tolerance from the petroleum contaminated soil located in industrialized areas of Chhattisgarh, India. Soil sediments were characterized by FTIR for the presence of aromatic compounds and further the heterotrophic and fuel degrader counts was estimated. The strains characterized were predominantly from the Bacillus species which showed mixed resistance patterns against antibiotics and heavy metals.

A wide range of microorganisms present in industrial effluent, exposed to different heavy metals, develop tolerance to such metal. Adaptation to the adverse environmental condition make them resistant to different antibiotics and various characters exhibited by them need to be explored. Twenty numbers of bacteria isolated from the effluent of a steel plant showed tolerance to heavy metals like Ni, Cr, Cd, Pb, and Hg and resistance to different antibiotics.

Resistance in pathogenic bacteria against antibiotics is a challenge for our clinicians for the management of various infections. The emergence of antibiotic resistance has caused great concern among health professionals and the prevalence of multidrug-resistant organisms has been increasing. Over-ambitious use of broad spectrum antibiotics is playing an important role in the increased incidence of infections due to MDR bacteria. Multiple drug resistance (MDR) mediated through R plasmids among Gram-negative bacteria has become a major nosocomial problem worldwide.

Heavy metals are hazardous to living things and causes deterioration of the environment. Nowadays, contamination of heavy metals in the soil and water has gradually increased by human activities. This study analyzed soils from two industrial sites in Myanmar and lead tolerant soil bacteria, E.coil and Alcaligenes sp. were isolated, and characterized. MIC value of lead for Alcaligenes sp. was 13 mM and for E. coil isolates was 10 mM, respectively.

A phenotypic characterization of thirteen root nodule bacteria recovered from wild legumes (Genista microcephala and Argyrolobium uniflorum) growing in arid eco-climate zones (Northeastern Algeria) was conducted using analysis of sixty-six phenotypic traits (carbohydrate and nitrogen assimilation, vitamin requirements, growth temperature, salinity/pH tolerance and enzyme production). Furthermore, SDS-PAGE profiles of total cell protein, antibiotic susceptibility and heavy metal resistance were performed.
