The invention belongs to the technical field of fermentation engineering and in particular relates to a prodigiosin producing strain and a method for producing prodigiosin through fermentation of the prodigiosin producing strain. The prodigiosin producing strain is acid producing klebsiella (Klebsiella oxytoca), is preserved on June 24th, 2013 in CGMCC (China General Microbiological Culture Collection Center) and has the preservation number of CGMCCNo.7816 and the preservation unit address of No.3 No.1 Courtyard, West Beichen Road, Chaoyang District, Beijing, Institute of Microbiology of Chinese Academy of Sciences. The prodigiosin producing strain can produce the prodigiosin through fermentation, an improved inorganic salt culture medium is adopted and is cultured away from light for 20-26 hours at a temperature of 24-28 DEG C and a rotating speed of 250-360rpm, and pigment yield can be 70-90mg/L. The produced prodigiosin is sensitive to natural light and ultraviolet rays and has an inhibitory activity to staphylococcus aureus, salmonella paratyphi and tritirachium album. The prodigiosin producing strain has a good application prospect in fermentation production of the prodigiosin and the fields of tumour suppression, food, cosmetics and the like.
