      abstract     = {The microbial inoculation of legumes such as soybeans is
                      crucial for thriving plant growth due to symbiotic nitrogen
                      (N) fixation and biological plant N fertilization. Soybean
                      requires microbial pre-inoculation before sowing using the
                      rhizobia strain Bradyrhizobium japonicum. Peat is typical
                      for this purpose, although not sustainable since it is a
                      finite resource. Here, we propose a straight-forwarding
                      route to prepare and apply polyglycerol-citrate polymer
                      (PGC), a biodegradable and fully renewable polymer, as a
                      carrier for Bradyrhizobium japonicum inoculants for
                      soybeans. This novel eco-friendly polymer combines the
                      advantages of a polymeric, water-soluble structure based on
                      biopolymers, which can protect the inoculant cells during
                      the seed inoculation process, with protective properties of
                      glycerol for bacterial cells and the contribution of citric
                      acid for metabolic processes. A greenhouse study was
                      conducted using soybean seeds coated with three different
                      proportions of PGC with B. japonicum planted in a sand
                      substrate free of external interference. Comparative results
                      of N content and δ15N signature in soybean plant parts
                      calculated from the natural abundance method associated with
                      viability tests showed equal or superior symbiotic
                      performance and nitrogen fixation rates to peat-based
                      inoculants, considered the gold-standard carrier for
                      inoculants. It ensured the shelf life of the inoculant
                      formulations, offering convenience for farmers and
                      environmental benefits through reduced fertilization.},
