The extent of decline in the population density of Rhizobium sp. exposed to Bdellovibrio was markedly reduced in the presence of montmorillonite, kaolinite or vermiculite but not by a soil clay fraction. Increasing levels of montmorillonite reduced the numbers of vibrios that appeared in a two-membered culture and allowed for greater survival of the rhizobia. Bdellovibrio and not Rhizobium sp. was retained when mixed with the three clay minerals, but no appreciable retention was evident with the soil clay
