摘要

Micronutrient deficiencies affect an estimated 2 billion people worldwide, which is one of the leading causes of mortality and disability. Plant production is thought to be significantly increased by microbiome, and efforts are being made to develop inoculants that would increase the concentration of micronutrients. In the present investigation, Fe chelator and zinc (Zn) solubilizing bacteria were isolated and identified as Fe-chelating Salipaludibacillus agaradhaerens EU-WRN-48 and Zn solubilizing Pseudomonas silesiensis EU-WRN-33 by molecular technique and used as consortium to enhance plant growth and Fe, Zn uptake in wheat. Results revealed that dual application of S. agaradhaerens EU-WRN-48 (Fe-chelating) and P. silesiensis EU-WRN-33 (Zn solubilizer) significantly enhanced the growth and physiological attributes in wheat crop. The maximum improvement of Fe and Zn content in wheat grain was observed in microbial consortium inoculated plant upto 61.33 ppm and 76.12 ppm over control respectively. These results strengthen the hypothesis that microbial assisted wheat biofortification could alleviate micronutrient deficiencies in humans, especially in areas with insufficient resources. It has been proposed that this consortium might be used to produce an efficient bioinoculant for sustainable and environment friendly wheat crop development. Therefore, we encourage farmers to employ this bioinoculants in place of harmful chemical fertilizers so that they can restore their natural agro-ecosystem environment and once more serve as India's breadbasket. Collectively, microbial consortium assisted successful biofortification of Fe and Zn in wheat, laying a foundation for further large-scale exploration of its applicability and efficiency.
