โฆ Synopsis
In this study, an attempt has been made to maximize the lipid production using response surface methodology (RSM). Levels of nitrogen, carbon, and inoculum were chosen as factors. The results indicated that inoculum level was very important in lipid production, followed by carbon and nitrogen levels. At higher levels of inoculum, the strain was found to be more tolerant to higher concentrations of sugar, and significantly increased lipid production was noticed. Through the fitted models of second order, as per RSM, carbon at 10.24%, nitrogen at 0.37 g/L, and inoculum at the 20% level resulted in maximum biosynthesis of lipids.
