Biodesulfurization of Dibenzothiophene by Decorating Rhodococcus erythropolis IGTS8 Using Montmorillonite/Graphitic Carbon Nitride

Fossil fuels are the main sources of human energy, but their combustion releases toxic compounds sulfur oxide. In oil industry, using optimal methods to eliminate from fossil is a very important issue. this study, performance montmorillonite/graphitic carbon nitride (a new hybrid nanostructure) in increasing biodesulfurization activity Rhodococcus erythropolis IGTS8 was investigated. X-ray diffraction, Fourier-transform infrared spectroscopy, field emission scanning electron microscopy and transmission were used for characterization nanoparticles. The effective factors process determined. Optimum conditions microorganisms designed Design Expert software. Experiments performed flask. results indicated that microorganism presence nanostructure increases by 52%. addition, nanostructure, are: 1. concentration nanostructure; 2. sulfur; 3. cell concentration. absence only factor sulfur. Through analysis variance, proposed models presented determine 2-hydroxy biphenyl produced (biodesulfurization activity) nanostructure. highly acceptable consistent with experimental data. Gibbs assay showed efficiency increased about 52%, which satisfactory result. decorated cells bioreactor significant increase compared nondecorated cells. Almost two-fold improvement obtained free
