A second order polynomial model was obtained using central composite design to understand the effects of interactions among these substrates on pullulan biosynthesis. Results indicated that, lower concentrations of CSL and DOJSC and higher concentrations of jaggery favoured pullulan production. The optimal nutrient composition (18% jaggery, 3% DOJSC and 0.97% CSL) as suggested by the model resulted in production of 66.25 g/L pullulan with a productivity of 0.92 g/Lh. Analysis of raw material cost component for pullulan production suggested that sole utilization of agri-residues may lead to development of cost effective process for pullulan production. date: 2014-03 date_type: published publication: International journal of biological macromolecules volume: 64 publisher: Elsevier Science pagerange: 252-6 refereed: TRUE issn: 1879-0003 official_url: http://www.sciencedirect.com/science/article/pii/S0141813013006612 citation: Mehta, Ananya and Prasad, G S and Choudhury, Anirban Roy (2014) Cost effective production of pullulan from agri-industrial residues using response surface methodology.
