Diversity and Distribution of Heavy Metal-Resistant Bacteria in Polluted Sediments of the Araça Bay, São Sebastião (SP), and the Relationship Between Heavy Metals and Organic Matter Concentrations
(2016-10-01)
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 ...
Monitoring heavy metals in royal sun medicinal mushroom, agaricus brasiliensis (Agaricomycetes)
(2019-01-01)
Agaricus brasiliensis is popular because of its nutritional and medicinal properties. Brazil supplies this edible mushroom to international markets, where quality standards are very restrictive regarding the allowable ...
Heavy metal resistance mechanisms in actinobacteria for survival in AMD contaminated soils
(Elsevier Gmbh, Urban & Fischer Verlag, 2005-09)
A site in the former uranium mining area of Eastern Thuringia near Ronneburg was investigated with regard to effects of acid mine drainage (AMD) on reactive transport and bioattenuation. Processes involved in this attenuation ...
Bioaccumulation of heavy metals in Limnobium laevigatum and Ludwigia peploides: their phytoremediation potential in water contaminated with heavy metals
(Springer Verlag Berlín, 2018-06)
Contamination with heavy metals in surface and groundwater is a threat to human health and ecosystems. Due to this, the need arises to remediate water polluted through ecological and profitable technologies, such as ...
Effect of co-contamination by pahs and heavy metals on bacterial communities of diesel contaminated soils of south shetland islands, antarctica
(MDPI AG, 2020-11)
Diesel oil is the main source of energy used in Antarctica. Since diesel is composed of toxic compounds such as polycyclic aromatic hydrocarbons (PAHs) and heavy metals, it represents a constant threat to the organisms ...
Metal-Resistant Rhizobacteria Change Soluble-Exchangeable Fraction in Multi-Metal-Contaminated Soil Samples
(Soc Brasileira De Ciencia Do Solo, 2018-01-01)
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 ...
