Abstract

Novel processes are provided for the embedding of microorganisms within a polymer matrix wherein the matrix comprises a polymer gel having a base of at least one polymer selected from the group of polysaccharides, in which said polymer is at least partially cross-linked. The embedded microorganism products are useful in the inoculation of leguminous and non-leguminous plants in order to increase their nitrogen-fixing potential and nutrition, respectively.
