Abstract

A MATHEMATICAL MODEL to predict the rhamnolipids production by Pseudomonas aeruginosa from OLEIC ACID in a two phase liquid-liquid batch reaction system, was developed in this study. The model was based on two theoretical assumptions: 1) the convective OLEIC ACID mass transfer is coupled to a bioreaction in the aqueous liquid bulk, and 2) the volume of the immiscible OLEIC ACID drops and the saturation concentration at the interface are a function of rhamnolipids production. The model was able to accurately predict the experimental growth of the Pseudomonas aeruginosa strain, and the rhamnolipids production data with OLEIC ACID as carbon source. This mathematical approach indicated a high correspondence between the saturation dimensionless profiles of OLEIC ACID at the interface and the experimental profiles of surface tension difference. This modeling approach may constitute a useful tool in the design and scaling-up of BIOREACTORS applied to the production of BIOSURFACTANTS with immiscible carbon sources.
