Multi-response optimization of rhamnolipid production using grey rational analysis in Taguchi method

Highlights • Optimization of rhamnolipid production under integrated Taguchi design and GRA.• The results were analyzed by using grey relational analysis.• In doing this, volumetric productivity of the process improved by 142%.• Total sugars concentration was the most influencing parameter.• This is a biocompatible production via sustainable technology.
