Descrição
Resumo:Toluene is one of the most frequent volatile organic compounds (VOCs) in contaminated groundwater due to its intensive use in industry, improper disposal, and accidental spills. Microbial bioremediation is a suitable and environmentally friendly technology for degrading organic contaminants frequently present in aquifers. However, polluted sites are often contaminated by a mixture of VOCs, which can hinder bioremediation activities since some compounds can adversely affect the biodegradation processes of the microorganisms. In this study, different concentrations of chloroform, dichloromethane, and 1,2 dichloroethane were added to a stable anaerobic toluene-degrading culture containing Aromatoleum sp., to assess their potential inhibitory effects
