Abstract
The anaerobic bioremediation of raw and treated hydrocarbon polluted water samples using Aspergillus niger and Pseudomonas aeruginosa has been investigated. The rate of bioremediation of the two polluted water samples was nearly the same as it took 65 days for effective bioremediation to occur with both microbes. The overall bioremediation effects, however, of Pseudomonas aeruginosa (bacteria) on the Biological Oxygen Demand (BOD) and the Total Hydrocarbon Content (THC) were higher than that of Aspergillus niger (fungi). Furthermore, the treated crude polluted water (TCPW) sample was easier to biodegrade than the raw crude polluted water (RCPW) samples. The bioremediation of the TCPW samples gave 99.5% for BOD and 98.9% for THC using bacteria while for fungi; it gave 96.1% BOD and 95.4% for THC. For the RCPW samples bioremediation with bacteria gave 96.6% for BOD and 96.0% for THC while bioremediation using fungi gave87.1% for BOD and 86.5% for THC.
