Abstract
|
|
|
|
Biodegradation of Quinoline by free and immobilized Bacillus brevis has been investigated. The rate of quinoline degradation by immobilized Bacillus brevis on coconut shell carbon is faster than the rate by the microorganism immobilized on foam pieces and free cells. A complete removal of 100 ppm of Quinoline in the sample was achieved at a hydraulic retention time of 20 hours with the biocatalyst prepared by immobilizing Bacillus brevis onto coconut shell carbon. The biocatalyst had a reasonable shelf life and desirable recycle capacity.
