title: [Use of highly dispersed materials for culturing and isolation of granular Agrobacterium radiobacter preparations ].
abstract: The effects of synthetic and natural high-dispersion materials on the growth of Agrobacterium radiobacter were studied. Natural minerals montmorillonite and palygorskite (10 g/l nutrient medium) were more potent than high-dispersion silica and its modified forms in stimulating growth of Agrobacterium radiobacter. The interaction of Agrobacterium radiobacter with clay minerals increased the survival rate of bacteria at supraoptimal temperatures. We elaborated new granular bacterial preparation, which enhanced the productivity of cucumbers by 12-15%.
