Aquatic ecosystem-derived biofertilizers such as\n                    <jats:italic>Magnetospirillum gryphiswaldense<\/jats:italic>\n                    (MSR-1) are promising sustainable substitutes and show strong agricultural potential due to their stress tolerance, adaptability, and plant growth-promoting traits. This study investigated the ability of MSR-1 to enhance the growth and productivity of tomato and paddy under normal, iron-deficient, and saline conditions. MSR-1 was cultured in modified\n                    <jats:italic>Magnetospirillum<\/jats:italic>\n                    Growth Medium (MSGM) under microaerophilic conditions, with SEM confirming its spiral gram-negative morphology and successful, non-destructive colonization on tomato and paddy roots and leaves. Moreover, HR-LCMS profiling of root exudates identified chemoattractant compounds such as quinic acid, tryptophan, quercetin, glucosinolates, and strigolactones, promoting bacterial attachment. Further,\n                    <jats:italic>Magnetospirillum<\/jats:italic>\n                    liquid biofertilizer (MLB) was formulated from MSR-1 cultures (1.5\u202f\u00d7\u202f10\n                    <jats:sup>8<\/jats:sup>\n                    cells\/mL) and applied at 20\u2013100% concentrations (25\u202fmL\/pot). Among the treatments, 20% MLB gave the best results under normal conditions, whereas 60% MLB was more effective under iron-deficient and saline stress conditions. In tomato, 20% MLB increased shoot length (73.5\u202fcm), chlorophyll content (4.5\u202fmg\/g), and fruit yield (1066.95\u202fg\/plant). Under stress, 60% MLB improved fruit yield (760\u2013800\u202fg\/plant) and boosted antioxidant enzymes (SOD 75\u202fU\/mg; CAT 15.5\u202fU\/mg). In paddy, 20% MLB enhanced shoot and root length (66.0 and 15.13\u202fcm), while 60% MLB under stress increased growth, carbohydrates, proteins, amino acids, phenols, and antioxidant enzymes (SOD\/CAT 49.63\/19.83\u202fU\/mg). Overall, MSR-1 offers a sustainable, effective biofertilizer option for managing soil salinity and iron deficiency.\n                  <\/jats:p>","DOI":"10.3389\/fmicb.2026.1848546","type":"journal-article","created":{"date-parts":[[2026,6,26]],"date-time":"2026-06-26T05:46:48Z","timestamp":1782452808000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Magnetotactic bacteria as biostimulants for enhancing the growth and yield of tomato and paddy under abiotic stress"],"prefix":"10.3389","volume":"17","author":[{"given":"Shraddha","family":"Shirsat","sequence":"first","affiliation":[{"name":"Marine Biotechnology and Bioproducts Laboratory, Department of Biomedical Sciences, School of Biosciences and Technology, Vellore Institute of Technology","place":["Vellore, Tamil Nadu, India"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.
