* Optimizing ultrasound-assisted extraction of prodigiosin by response surface methodology.

- Prodigiosin extraction from dried Serratia marcescens jx1 cells using ultrasound-assisted extraction was optimized. The experiment was carried out in accordance with a central composite design (CCD) three-level and single-variable approach. The extraction time, extraction temperature, and solute to solvent ratio with the application of ultrasonication were optimized using response surface methodology (RSM) to maximize the extraction of prodigiosin from dried S. marcescens jx1 cells. The response of prodigiosin was determined using spectrophotometry. A quadratic model was established to predict the prodigiosin extraction yield. The analysis of variance showed that the quadratic model significantly contributed to the response of prodigiosin. The optimal extraction parameters were an extraction time of 17.5 min, an extraction temperature of 23.4°C, and a solvent-to-solute ratio of 1:27.2. Under these optimum conditions, the average prodigiosin yield was 4.3 g±0.02 g from 100 g of dried cells, which matches the predicted values. The obtained optimum conditions for prodigiosin extraction provide a scientific basis for the economical large-scale production of prodigiosin.
