Rhizosphere bacteria help protein accumulation in soybean seeds

Abstract

The use of rhizobacteria as biofertilizers is one of the most promising biotechnologies to improve primary
production with low inputs in fertilizers. In this context, the main goal of this study was to establish if the interaction
between different rhizobacteria strains with Glycine max L. plants have a positive effect on the total soluble protein,
carbohydrates and lipids content of soybeans. Our results revealed that there are no significant differences between the
seeds produced by inoculated plants and those produced by the non-inoculated plants regarding soluble reducing
carbohydrate content, lipid content and relative humidity. In the case of soluble protein content, rhizobacteria inoculated
plants produce beans that contain a greater amount of soluble protein per gram. No qualitative differences could be
shown, making our tested rhizobacteria strains an appealing strategy for improving soybean protein production.
