KING’S MEDIUM B BASE W/ 1.5% AGAR (FDA BAM, 1998)

Description

Pseudomonas aeruginosa is known to produce two types of pigments, pyocyanin and fluorescein which is a characteristic property and aids in its isolation from from clinical and food samples. An additional pigment entitled pyorubin was reported by King. Pyocyanin is green, fluorescein is fluorescent yellow and pyorubin is reddish brown in colour. Some strains produce all the three pigments while the others produce one or two. Kings Medium B Base w/ 1.5% agar, recommended by FDA BAM is particularly suited for fluorescein production. This medium can be used as a general medium for the non-selective isolation and pigment production of Pseudomonas species from foods, cosmetics etc.
