Here is the yellowish-green bacterial pigment which is play a crutial role during the iron starvation. This pigment contains pseudomonas species which is opportunistic pathogen infecting humans with compromised natural defences.
A colorful pigment, yeellowish-green pigment, a petri dish shows the yellowish-green colony of the Pyoverdine.
Pyoverdine, the yellowish-green, water soluble, fluorescent pigment of the fluorescent Pseudomonas species. . There are three distinct structural parts constitute pyoverdines, firstly the fluorescent chromophore, deriving from dihydroxyquinoline which is attached via its carbonyl group. Secondly, a type type specific peptide composed of 6 to 14 amino acids and finally a small side chain corresponding to a carboxylic acid derivative.
Pyoverdine as a fluorescent it acts a ready marker for bacterial differentiation, as a siderophore it plays a significant physiological function in satisfying the absolute iron requirement of these strictly aerobic bacteria, which help in the growth under the iron-limiting conditions. Pyoverdine is crucial for pathogenesis in mammalians infections. This bacterium pigment is important for iron extraction when it is translocates into the host, attaches to the ferric iron.
Prevention of iron overload toxicity. Inhibition of pathogenic bacterial growth(as an iron chelator). Specific inhibitor of fluorescent pseodomonads strains.
