To investigate the role of biological processes in bacterial transport through poroud media, six rod shaped and motile bacteria were isolated from a crude oil sample. A multi stage screening procedure was utilized to select the most appropriate isolate in microbial enhanced oil recovery applications (MEOR). It was identified and registered as Bacillus licheniformis MS3 in GenBank database. After that, the physical properties and chemical structure of its biosurfactant were determined and it was proved to be a new lipopeptide biosurfactant which was called licheniformin. Power law logistic model was utilized to investigate the kinetics growth of the MS3 strain on insoluble carbon sources ...
