Medium Optimization of Gamma Linolenic Acid Production in Mucor rouxii CFR-G15 using RSM

Omega-6 polyunsaturated fatty acids has both pharmaceutical and neutraceutical importance. Central composite rotatable design (CCRD), along with response surface methodology (RSM), was employed to optimize the medium components for maximum production of gamma linolenic acid (GLA) from Mucor rouxii CFR-G15. Nutritional parameter such as carbon (glucose) and nitrogen (yeast extract and ammonium nitrate) sources were focused in this study to enhance the GLA production. The optimal conditions for maximizing GLA production (18.55%) were at 65 g glucose per liter; 3.5 g yeast extract per liter, and 0.5 g ammonium nitrate per liter. Thus, by using CCRD with RSM, it is quite possible to determine the accurate values of the fermentation parameters where maximum production of GLA is achieved.
