(Ferreira et al. 2019). Therefore, its biosafety issue must be resolve before largescale field application. There are some initial reports indicating the synthetic siderophores. Williams et al. 2019 have reported coelichelin and several derivatives as
ferric iron delivery vehicles for Pseudomonas aeruginosa. Sridhar et al. (2018) have
synthesized gobichelin B siderophore which is found in Streptomyces sp. Sockwell
and Wetzler (2019) have reported polyhydroxamic acid siderophores, which showed
a higher preference for Fe
III
. Pros and cons of biological inoculants and natural or
synthetic siderophores at field level are yet to be established.
Acknowledgment Visiting fellowship from Indian Academy of Sciences is deeply acknowledged. Author is thankful to Dr. Kalyani Dhusia for her support and going through the
manuscript.
