Siderophores are low-molecular-weight and high-affinity molecules produced by bacteria under iron-limited conditions. Due to the low iron (III) (Fe+3) levels in surface waters marine environment, microbes produce a variety of siderophores. In current study, halophilic Bacillus taeanensis SMI_1, Enterobacter sp., AABM_9, Pseudomonas mendocina AMPPS_5 were isolated from water Kalinga beach, Bay Bengal (Visakhapatnam, Andhra Pradesh, India) investigated for siderophore production using Chrome Azurol S (CAS) assay.
