Plant-growth-promoting bacteria show promises in crop production; nevertheless, innovation their stable delivery is required for practical use by farmers. Herein, the composite of poly(vinyl alcohol)/poly(vinylpyrrolidone) plasticized with glycerol and loaded microbial consortium (Bacillus subtilis plus Seratia marcescens) was fabricated engineered onto canola (Brassica napus L.) seed via electrospinning. Scanning electron microscopy showed that biocomposite a one-dimensional membrane, which encapsulated microbes multilayered nanostructure, interfacial behavior between microorganism beneficial safer farming. A universal testing machine thermogravimetric analysis demonstrated holds sufficient thermomechanical properties handling management. spectroscopic study resolved living hybrid–polymer structure proved plasticizing role glycerol. swelling supports degradation hydrophilic environment as result leaching plasticizer, important sustained release cells. shelf life supported coat placed threshold level [5.675 ± 0.48 log10 colony forming units (CFU)/seed] maintained satisfactory viability 15 days at room temperature. An antifungal nutrient-solubilizing could provide opportunities to biocontrol diseases improve nutrient acquisition plant. pot documents better performance on germination, seedling growth, leaf area, plant dry biomass, root system. chemical improved effectiveness bioinoculant root–soil interface, where they survive, flourish, increase pool status. In particular, this presents advances fabrication encapsulation, preservation, release, efficacious microorganisms seeds precision
