ABSTRACT
The present work aimed to give an economical destiny to the produced water, a residue generated by the oil and gas industry by means of producing bioactives such as xanthan gum and ramnolipid. These compounds are often used in combination during enhanced oil recovery strategies. On the other hand, reports on co-culture of bacterial strains that are responsible for their production are rare. This research shows a factorial design method associated with surface response analysis to optimize carbon sources, sucrose and crude glycerin, and fermentation agents for culturing Xanthomonas campestris and Pseudomonas aeruginosa using the described conditions. After the critical point validation resulting in xanthan and ramnolipid production of 8.69 and 4.80â
