[Granulated preparations of azotobacter in a clay-mineral base].
Interaction of Azotobacter chroococcum 20 cells with clay minerals increased their viability at supraoptimal temperatures. Therefore, clay minerals were used to develop granular bacterial preparations with high viable cell counts and stable compositions during long-term storage. The titers of viable bacteria in the preparations remained 60-70% of the initial level after 12-month storage.
