“…Besides, biosorption involving chelation, ion exchange, complexion, adsorption, absorption or micro-precipitation can also act as a potential way for remediation. Indigenous fungi achieved a cadmium removal of 72.4% from municipal solid wastes leachate at spore concentration of 10-5, pH of 6.0 and temperature of 45 oC (Awasthi et al, 2017). Bioleaching or microbial reduction can be applied for As treatment using exogeneous bacteria, but the treatment cycle is long (Lee et al, 2015;Yamamura et al, 2008).…”

Disposal of municipal solid waste (MSW) can be considered a risk to human health representing a great environmental problem in several countries. MSW landfills are a significant source of toxic elements in the environment. Microorganisms able to thriving in leachate wastewater may exhibit metabolic machinery to synthesize a wide range of enzymes able to degrade and/or discolor toxic compounds from leachate. The use of non-pathogenic microbial cells for human health, recovered from leachate for biotechnological application, can be considered a promising approach in bioremediation processes of toxic compounds found in these environments. The present work aimed to the isolation, antibiotic resistance evaluation and leachate discoloration by microorganisms isolated from landfill leachate of Foz do Iguaçu. Forty bacteria and fifteen filamentous fungi were isolated. From these, six bacterial showed resistance at least one tested antibiotic, while six fungal isolates showed resistance to the antimycotic nystatin. CCMIBA_4L (unidentified bacteria) and Paecilomyces sp. CCMIBA_5N, were able to discolor 19.15% and 25.26% of the leachate, respectively. The results of the present work encourage future studies to characterize the enzymes involved in the discoloration and degradation of the leachate. The findings demonstrated the potential for the use of microorganisms from landfill leachate as bioremediation tools.

“…As hifas fúngicas podem acumular metais por ligação de cargas em suas paredes celulares e impedir a concentração no tecido vegetal MALIK et al, 2014;VIJAYARAGHAVAN;BALASUBRAMANIAN, 2015;AWASTHI et al, 2017), mas a concentração de metais nas raízes e parte aérea do tratamento inoculado (CJF) não diferiu das plantas sem inoculação em solo contaminado (CJ) (TABELAS 4 e 5). Portanto, mecanismos fisiológicos de proteção ao PSII desconhecidos podem ter desencadeado com a aplicação do consórcio fúngico.…”
