Abstract

The use of fungi as catalysts for the decontamination of water is a useful tool in environmental biotechnology, since it allows the development of technologies that can be used in the recovery of aquatic ecosystems impacted by oil. The ability to remove polycyclic aromatic hydrocarbons (PAHs) from water with fungal catalysts Aspergillus species Aspergillus niger and Aspergillus flavus isolates Bay Amuay, spreading inoculums were used to measure the hidrocarbonoclastic capacity by determining the increase in assessed biomass dry weight and by decreasing the concentration of PAHs microcosms spectrophotometrically. Fungal removal percentages catalysts showed 70 % -80 % between one and three months and 100 % per year. Finally a technological process scheme for reducing environmental liabilities based on green chemistry is proposed.

Keywords: Aspergillus niger, Aspegillus flavus, PAHs, environmental biotechnology,             Amuay Bay.
