LIQUID BACTERIAL INOCULANTS WITH EXTENDED USEFUL LIFE AND ENHANCED STABILITY ON SEEDS Russian patent published in 2011 - IPC C12N1/04 A01C1/06 

FIELD: food industry.

SUBSTANCE: method for production of the preparation of a partially dehydrated liquid bacteria inoculant involves: production of a liquid inoculant of bacteria grown basically till stationary phase with the bacteria represented by one or more genera of Rhizobium, Bradyrhizobium, Pseudomonas and Serratia and addition of a dehydrating additive including a desiccant to the liquid bacteria inoculant in an amount sufficient for partial dehydration of the liquid bacteria inoculant to produce the preparation of the partially dehydrated liquid bacteria inoculant; the desiccant is represent by one or more compounds selected from among trehalose, sucrose, glycerine, triethylene glycol and mannitol in an amount from approximately 5% to approximately 50% (wt/vol) of the preparation of the partially dehydrated liquid bacteria inoculant. Subsequent application of the produced onto a dry medium enables production of a dry granular bacteria inoculant.

EFFECT: invention allows to enhance bacteria survival ability and stability in inoculants, in packages and on seeds.
