A process for drying bacteria characterized in that: (a) an aqueous suspension comprising at least one bacterium and one or more protective agents, the bacterium representing at least 3% of the dry matter of the suspension, is sprayed into a hot atmosphere (atomization), the temperature of which is at most 500°C for a time suitable for obtaining a powder whose residual water content is at least 5% by weight with respect to the total weight of the powder; and (b) the powder resulting from step (a) is subjected to a step of drying under reduced pressure of at most 3 x 104 Pa in order to obtain a powder whose residual water content is at most 4% by weight with respect to the total weight of the powder; and a dried bacterial formulation obtained by the process. |
