Reaction engineering studies on the biodegradation of anthracene on bioremediation of diesel contaminated soil using Acinetobacter sp (ATCC No. 14293)
In the present investigation bio-degradation of anthracene, a polyaromatic hydrocarbon, from its simulated mixture in methanol, has been studied using a monoculture strain, (Acinetobacter sp. (ATCC No. 14293)), within the concentration range 500-800 mg/dm(3). In a separate attempt bioremediation of diesel contaminated soil to reduce total aromatic content using the same bacterial strain has been carried out. The main emphasis of this investigation is to understand the complex reaction engineering behaviour involved in both the above bioprocess systems. It is observed that while Monod's classical substrate uninhibited model can be used for simulation purpose for the biodegradation of anthracene, the reaction engineering behaviour of the bioremediation of soil can be expressed by coupling Monod's classical equation with first order cell decay rate. In both the cases the concerned intrinsic kinetic parameters have been evaluated.
