Heavy metals influence the population size, diversity, and metabolic activity of bacteria. In turn, bacteria can develop heavy metal resistance mechanisms, and this can be used in bioremediation of contaminated areas. The ...

Microbial solubilizing of metals in acid environments is successfully used in industrial bioleaching of ores or biomining to extract metals such as copper, gold, uranium and others. This is done mainly by acidophilic and ...

Sulfate-reducing bacteria (SRB) can be used to remove metals from wastewater, sewage, and contaminated areas. However, metals can be toxic to this group of bacteria. Sediments from port areas present abundance of SRB and ...

Some heavy metals are essential for extremely important metabolic reactions and are also required as trace elements by various organisms. Others heavy metals have no biological role and are harmful, even at very low ...

Soil management using fertilizers can modify soil chemical, biochemical and biological properties, including the concentration of trace-elements as cadmium (Cd), chromium (Cd) and nickel (Ni). Bacterial isolates from Cd, ...

Anthropogenic pollution has a huge impact on the water quality of marine ecosystems. Heavy metals and antibiotics are anthropogenic stressors that have a major effect on the health of the marine organisms. Although heavy ...

The genus Streptomyces comprises a group of bacteria species with high economic importance. Several of these species are employed at industrial scale for the production of useful compounds. Other characteristic found in ...

Transport properties of metals in solid, liquid, gas or plasma phases are an open area of research, both theoretically and experimentally. Concretely, there are no measurements available for the resistivity of gas phase ...

We study the electrical characteristics of metal-semiconductor-metal HfO2_x-based devices where both metal-semiconductor interfaces present bipolar resistive switching. The device exhibits an unusual current-voltage ...

There is a complex interaction between various components of the soil ecosystem, including microbial biomass and soil chemical contaminants such as heavy metals and radionuclides, which may greatly affect the efficiency ...
