Metaproteomica e bioquimica de solos contaminados por hidrocarbonetos e metais pesados

TL;DRAbstract

Hydrocarbons, heavy metals and agricultural defensives are high risk pollutants to human health. These pollutants are constantly introduced into the environment as a result of petrochemical, industrial, agricultural activities and our modern life style, requiring remediation processes that are used to their complete elimination. Bioremediation is a process carried out by living organisms which has great potential for the recuperation of contaminated environments, but the lack of information about the factors that regulate growth and metabolism of microbial communities in polluted environments limits its implementation. Soil biochemistry techniques and metaproteomics analyses can assess the microbial activity and identify the physiological changes resulting from exposure to toxic agents. The objective of this study was to determine biochemical parameters such as: respiration, microbial biomass, qCO2 and activities of specific enzymes involved in major biogeochemical cycles, as well as t
