Fig. 5From: Unearthing the genomes of plant-beneficial Pseudomonas model strains WCS358, WCS374 and WCS417Overview of siderophore production by the WCS strains and their mutant derivatives. Maximum amount of 2,2-bipyridyl in KBA that still allowed growth of strains after 48Â h is indicated. Photographs display production of an orange halo by the bacterial strains on CAS agar, which is indicative for siderophore production. Abbreviations stand for Wild type (WT), pyoverdine (PVD), pseudomonine (PSM), pyochelin (PCH) or salicylic acid (SA). Production of pyochelin by WCS417 has not been demonstratedBack to article page
