 The present invention provides blue pigment producing pseudomonas fluorescens strain B1 CGMCC No. 1194, and the blue pigment producing process therewith. The blue pigment producing process includes the following steps: culturing blue pigment producing pseudomonas fluorescens strain B1 CGMCC No. 1194 through fermentation at 4-30 deg.c for 24-240 hr to obtain thallus; and crushing the thallus cells to obtain blue pigment. The liquid culture medium includes: tryptone 8-12 g, yeast extract 4-6 g, glucose 0.8-1.2 g, dipotassium hydrogen phosphate 2-4 g and water 1000 ml. The blue pigment thus produced is natural product and has no latent harm and no side effect on animal body, so that it may be used widely in food industry.
