| 摘要 |
The invention relates to a method of producing lyophilized microorganisms, such as lyophilized bacteria, of the type in which a culture medium is inoculated with one or more strains of microorganisms during one of the steps of the method. The invention is characterised in that, prior to the inoculation step, the culture medium is treated with a treatment gas comprising an inert gas or a reducing gas or a mixture of such inert and reducing gases, in order to obtain a determined redox potential value Eh for the medium, which is less than the value obtained when the medium is in equilibrium with the air.
