<b>Tolerance to Polycyclic Aromatic Hydrocarbons (PAHs) by filamentous fungi isolated from contaminated sediment in the Amazon region

Abstract: ABSTRACT. Tolerance to Polycyclic Hydrocarbons Aromatic (PAHs) is considered an important characteristic when assessing the bioremediation potential of microorganisms. Given this, the objective of this research was to assay filamentous fungi from the Amazon region, isolated from sediments with differents levels of contamination by PAHs, for tolerance to phenanthrene and pyrene. To achieve this, fungal cultures plugs (5 mm), obtained after 7 days growth, were transferred to petri dishes containing 20% Sabouraud… Show more

“…Comparing the variation of PAH components identified at all sampling stations (Tables 4-6), the types of PAH in the sediment samples were more varied, followed by the sponge samples, and then the seawater and fish samples [14,86,87]. The types of PAH pollutants identified in each sample showed that the PAH contained in the sediment samples were similar to those found in the sponge samples, while the seawater samples showed similar results to the fish samples [92,93]. This result is quite rational if we consider that sponges tend to settle at the bottom of the water (sediment), and the dominant habitat of fish is the water.…”

“…A aplicação de inseticidas químicos é o método mais aplicado há muitos anos em diferentes países. Entretanto, apesar de eficientes, muitas consequências negativas foram provocadas pela elevada e contínua utilização desses produtos, como a contaminação ambiental, a eliminação de espécies não-alvo, o acúmulo na cadeia alimentar e a seleção da resistência nos mosquitos (NASCIMENTO e MELNYK, 2016;CARVALHO e MOREIRA, 2017;OLIVEIRA et al, 2017;SOUZA et al, 2017).…”

“…Dentre os estudos qualitativos, destacam-se a análise da formação do halo de degradação em meios de cultura contendo ácido gálico e guaiacol, além da capacidade de descoloração do corante têxtil Remazol Brilhante Blue R (RBBR), entre outros (Rodríguez, 2014;Lee et al, 2014). Quanto aos testes quantitativos, a literatura tem demonstrado a realização de estudos sobre a atividade de enzimas do complexo fenoloxidases, tais como lacase e certas peroxidases (Barbosa, 2010;Colla, 2008;Lee et al, 2014), testes in vitro da tolerância aos contaminantes de interesse, bem como de biodegradação, análise de metabólitos e capacidade de mineralização (Argumedo-Delira et al, 2012;Souza et al, 2016;Souza et al, 2017).…”
