PROCESS OF PREPARATION OF INOCULUMS HAVING A LOW WATER ACTIVITY AND AN IMPROVED RESISTANCE TO TEMPERATURE AND REHYDRATATION

摘要

Inocula having a long storage life and improved resistance to temperature and rehydration and a method of preparing them are disclosed. The method of the invention comprises admixing a culture medium containing microorganisms of the genus Rhizobium and at least one carbohydrate source in a polymer gel and then lowering the water activity of the resulting inoculum and maintaining the water activity at less than 0.1.
