| description | The invention discloses serratia marcescens RZ 21-C6 and application thereof. The preservation number of the serratia marcescens RZ 21-C6 is CGMCCNo.12714. The mutant strain has the advantages that the utilization efficiency of a substrate, the genetic stability and the yield of prodigiosin are high, and the utilization effect of the mutant strain on xylose is particularly good. In a 5L fermentation tank, pesticide residue straw hydrolysate with xylose as a main component is low in price, a biomass carbon source is developed for production of the prodigiosin, the yield of the prodigiosin can reach 15-20 g/L during multi-batch fermentation, and the conversion rate of total reducing sugar directly used for prodigiosin synthesis is 20% or above. The method for producing the prodigiosin through the serratia marcescens at normal pressure and room temperature by means of plasma mutant strain and the utilization of the xylose and the pesticide residue straw hydrolysate by the serratia marcescens can promote achievem |
