Overview

In vitro experimental study demonstrates reduction of organic pollutant levels in palm oil mill effluent by Aspergillus lipase, suggesting potential bioremediation utility.

Key Points

To evaluate the bioremediation potential and kinetic activity of extracellular lipase produced by an isolated Aspergillus sp. on the physicochemical parameters of palm oil mill effluent.
Aspergillus sp. was isolated from palm oil mill effluent-impacted soil in Umunneochi, Abia State, Nigeria, and verified via standard microbiological and biochemical techniques.
Extracellular lipase production was screened using an optimized culture broth containing p-nitrophenyl palmitate (p-NPP), with peak yield measured over a multi-day fermentation period.
The enzymatic degradation of palm oil mill effluent was tracked across varying conditions, monitoring changes in pH, dissolved oxygen, biological oxygen demand, total organic carbon, and total organic matter.
Lipase secretion by the isolated Aspergillus sp. reached maximum production on day 5 of culture fermentation.
Enzyme activity on the effluent peaked at pH 5.0 after 168 hours of treatment.
Enzymatic treatment reduced total organic carbon from 102.34 mg/ml to 56.2 mg/ml, total organic matter from 125.87 mg/ml to 68.15 mg/ml, dissolved oxygen from 6.21 mg/ml to 4.52 mg/ml, and biological oxygen demand from 4.89 mg/ml to 2.89 mg/ml.
