| titleOfInvention | Method for preparing and purifying prodigiosin |
| abstract | The invention discloses a method for preparing and purifying prodigiosin. According to the method, serratia marcescens is utilized to produce strains; a crude product of prodigiosin is obtained through fermentation culture of mother seeds of serratia marcescens and extraction and condensation of red metabolites; and the crude product of prodigiosin is purified by the methods of silica gel column chromatography and high performance liquid chromatographic separation and subjected to low temperature freeze drying under vacuum so as to obtain a high pure product of prodigiosin. The purity of the high pure product prepared in the invention is greater than 98%; the method for preparing the product is highly effective; organic solvents used in the method can be recovered for cyclic utilization through rotary evaporation. |
