Abstract

We evaluated the bioremediation potential of petroleum-derived compounds using fungal strains isolated from marine samples collected on the coast of the states of Paraná, Brazil. About 75 isolated filamentous fungi were subjected to assays including decolorization of the synthetic dye Remazol Brilliant Blue R (RBBR), tolerance to diesel oil, production of bioemulsifying and degradation of pyrene. Nine isolates could decolorize RBBR between 3.4% and 88.16%. Ten were able to tolerate diesel oil and/or pyrene. One isolate was able to produce compounds with emulsifying properties. Three strains, Trichoderma sp. FM14 (Penicillium spp. FM02 and FM16, and FM14) were able to degrade pyrene between 33.0 and 42.4%, after 8 days. The results of the present work encourage future studies to optimize enzymatic conditions using isolates with biotechnological potential in bioremediation studies of marine environments contaminated with industrial pollutants including hydrocarbons derived from petroleum such as diesel oil and PAHs and synthetic dyes.

海洋丝状真菌的分离及其在生物修复过程中的潜在应用。

我们利用从巴西巴拉那州海岸采集的海洋样本中分离出的真菌菌株，评估了石油衍生化合物的生物修复潜力。我们对约 75 种分离的丝状真菌进行了检测，包括合成染料雷马佐亮蓝 R（RBBR）的脱色、对柴油的耐受性、生物乳化剂的产生以及芘的降解。九个分离菌株对 RBBR 的脱色率在 3.4% 到 88.16% 之间。10 个分离物能够耐受柴油和/或芘。一种分离菌株能够产生具有乳化特性的化合物。三株菌株（毛霉菌属 FM14、青霉属 FM02 和 FM16 以及 FM14）能够在 8 天后降解 33.0% 至 42.4% 的芘。本研究的结果鼓励今后的研究优化酶解条件，利用具有生物技术潜力的分离菌株对受到工业污染物污染的海洋环境进行生物修复研究，这些污染物包括从石油中提取的碳氢化合物，如柴油、多环芳烃和合成染料。
