Alginate Bead as Synthetic Inoculant Carriers for Bradyrhizobia

抄録

Bradyrhizobium japonicum entrapped in a calcium alginate matrix (alginateinoculant) released the cells at constant rate, which enables bradyrhizobia to infect the host plants efficiently. Alginate-inoculant was more competitive for nodule formation than perlite- or liquid-inoculant. Alginate-inoculant could be stored for longer period than perlite-inoculant. Entrapping B. japonicum with phototrophic bacteria (Rhodopseudomonas capsulata) in alginate beads could keep moisture of the beads, hence, extended the storage life of the inoculant.
