“…Interestingly both pyoverdine and azotobactin are mixed ligand siderophores. Studies have shown that fluorescent pigment pyoverdine from Pseudomonas aeruginosa is one such example that is known to be a powerful scavenger and efficient transporter of Fe(III) [23][24][25]. In the current investigation, the ability of the pigment to chelate iron from the CAS medium was studied.…”

“…Also this is the first report that shows a carotenoid pigment to have the ability to chelate iron. The only other pigment reported so far with this ability is the fluorescent pigment pyoverdine from Pseudomonas [24,25].…”

“…Sand dune bacteria, Pseudomonas aeruginosa TMR2.13 can grow on sodium benzoate up to 2 % and Bacillus sp. can tolerate up to 1 % of sodium benzoate [23,25,26]. Earlier studies have shown that utilization of the aromatic compound puts a greater stress on the bacteria for the demand of oxygen as a result of which they downplay the formation of pigment [23].…”

Mangroves are unique ecosystems in the coastal tropical and subtropical regions of the Earth. The fluctuation in salinity due to tidal action results in a prolific population of adhered halophilic and halotolerant bacteria in this ecosystem. In this study, a pigment producing adhered bacterial strain Halobacillus trueperi MXM-16 was isolated from mangrove plant litter of Goa. This strain was moderately halophilic, Gram positive rod, catalase positive and capable of utilizing sodium benzoate as a source of carbon. H. trueperi MXM-16, produced a siderophore that was hydroxamate in nature. The non-diffusible yellow pigment was a carotenoid and HPLC studies revealed a peak that was indicative of astaxanthin as one of the component. Further studies on the pigment exhibited its ability to chelate iron from the chrome azurol sulphonate medium behaving as an additional mechanism for iron acquisition.

“…Siderophore is producing in fungi due to Fe acquisition by different plant species (GAONKAR and BHOSLE, 2013). Chelation through binding toxic metals to siderophores triggers the enhancement of plant Fe uptake capacity and the decrease of free metal ion concentration (DIMKPA ET AL., 2008).…”

“…Many other metals and amino acids were found to suppress or stimulate siderophore production in bacteria [2,3]. Effect of metals on the efficiency of siderophore production by bacteria is essential for potential applications in bioremediation of metal-contaminated iron-deficient soils, especially in the microbe-assisted phytoremediation processes [4]. Metalresistant siderophore-producing bacteria play an important role in the successful survival and growth of plants in metal-contaminated soils [5].…”

In this study, siderophore-producing bacterial species have been isolated from soils contaminated with diesel oil. In P. aeruginosa (P-7) production of siderophores was inhibited at concentrations of ZnSO4 and CoCl2 of 2000 µM, while B. subtilis (BS-1) has increased siderophores production at similar concentrations of CoCl2 and ZnSO4. The same bacteria have increased the production of siderophores in presence of streptomycine (512 mg/ml). In B. subtilis the production of siderophores was inhibited by cefuroxime. The results show the effect of metals on the efficiency of siderophore production by bacteria for potential application in bioremediation of metalcontaminated iron-deficient soils in the microbial assisted phytoremediation processes. The results include the effect of metals on siderophore production efficiency of the bacteria used for the bioremediation of metal-contaminated soils. In conclusion, it has been found that heavy metals and antibiotics significantly effect the production of siderophores by bacteria.
