Biodegradation of heavy fuel oil by newly isolated strain Enterobacter cloacae BBRC10061: study on unstructured kinetic models and innovative equation
Author(s):
Abstract:
Modeling process is very important and valuable to predict process outcome, especially to bioprocesses which are intricate. Because of complex hydrocarbon compounds and oscillations happened in the medium of process, biodegradation of mazut has not already been investigated by mathematical models. In this study, an indigenous bacterium was isolated from oil contaminated soil to investigate biodegradation of mazut at different experimental conditions. Data resulted from mazut degradation, pH, and electrical potential in the medium were recorded. Some kinetic models reported and combinations of them were investigated to practically modeling the process. In addition, a new equation, that can predict various phenomena, was applied to functionalize changes of mazut concentration, pH, and electrical potential. Any of the kinetic models didn''t have potential for modeling behavior of mazut biodegradation at different conditions. Opposed to them, the novel equation was able to predict desirable parameter using two variables, and functionalize data by appropriate coefficients.
