The purpose of this work was to propose sustainable solutions for advanced oil recovery by evaluating the ability bacterium Pseudomonas sp. in biotransformation alkanes, addition determining strain growth patterns under extreme conditions. For this, initially carried out laboratory conditions, which crude fractionated obtain saturated fraction used experiment. bacterial tolerance salinity and t...

For microbial enhanced oil recovery (MEOR), different mechanisms have been introduced. In some of these papers, the phenomena and related to biosurfactants produced by certain microorganisms were discussed, while others studied direct impacts properties on mechanisms. However, there are only very few papers dealing with interfacial properties. present work, three bacteria MJ02 (Bacillus Subtili...

a bacterial strain (designated as alcaligenes sp. ms-103) isolated from oil sample of the aghajari oilfield in the south of iran, was able to produce an effective extracellular lipopolysaccharide biosurfactant (1.2±0.05 g/l) on molasses as a sole carbon source. the highest surface tension reduction to level 20 mn/m was achieved by biosurfactant produced by cells grown on molasses under optimum ...
