摘要
Mangrove ecosystem is a rich source of manglicolous fungi.While much information is available on diversity of these fungi,their siderophores have not been explored yet.The present study was carried out with a view to explore siderophore production potential of manglicolous fungi along Ghogha Coast,Gulf of Khambhat,Gujarat,India.From four different mangrove samples viz.rhizosphere,rhizoplane,water and sediment,thirteen fungi belonging to Ascomycota were isolated,which were all siderophore producers.Their chemical characterization indicated siderophores of twelve fungi to be hydroxamates while one isolate Emericella nidulans exhibited a novel behaviour.Emericella nidulans a producer of both;hydroxamate and catecholate siderophore,a behaviour uncommon amongst fungi.The data revealed that exploring manglicolous fungi could reveal novelty in structural diversity of siderophore reflecting their unique ecological roles like avoiding siderophore piracy and oxidative stress for reclamation of mangrove associated coastal habitats.
