The present invention belongs to the field of agriculture, more particularly to the field of organic fertilizers which contain cultures of live and active microorganisms. The invention relates to novel bacterial strains simultaneously exhibiting production of phosphatases for mineralization of organic phosphorus compounds, and phosphorus solubilisation for solubilizing insoluble phosphorus salts. Further, the invention also relates to an improved method for encapsulation of bacteria and a bio fertilizer comprising encapsulated bacteria prepared by the said process.Sodium alginate, calcium chloride, starch and optionally a colouring are used as external encapsulation media, wherein the bacteria are added to the encapsulation mixture with their whole microbial media (cells plus media containing unprocessed components and microbial products). This is essential, since microbial products have stimulus effects on plants while residual components of medium can bust microbial activity and help microbial culture activation. A further characteristic of the process is slow drying of encapsulates at mild temperatures, which results in evaporated water and further cell stabilization.
