Biodegradation activity of Aspergillus niger lipase isolates from a tropical country garage

Abstract

Microbial biodegradation of oil pollutants and their derivations has become the most environmental-friendly method in the developing world. Lipolytic enzyme; Aspergillus niger extracted from oil polluted soil has been studied, examined and found to degrade Polyaromatic Hydrocarbons found in petroleum contaminated soil. A. niger can produce Bio-Surfactant at 25 °C and 35 °C that can biodegrade oil hydrocarbons. 24 hours at 35 °C it can reduce surface tension from 55 Nm/m to 25.3 Nm/m at different percentages of crude oil.
