ABC is suggested to be suitable as a carrier for biocontrol agents, offering them a protected niche as well as delivering phosphate to plants, meanwhile re-using P from waste of the food chain. Ninety-seven bacterial isolates from different soils were tested for their potential to dissolve P from ABC. Of these isolates, 60% showed positive scores; they belonged to the genera <i>Arthrobacter</i>, <i>Bacillus</i>, <i>Burkholderia</i>, <i>Collimonas</i>, <i>Paenibacillus</i>, <i>Pseudomonas</i>, <i>Serratia</i>, and <i>Streptomyces</i>. Twelve isolates from different taxonomic groups were selected for further research on growth ability and survival in ABC, and on their potential to control plant pathogens. The highest concentrations of P were dissolved by <i>Pseudomonas chlororaphis</i> and <i>Bacillus pumilus</i>, followed by <i>Paenibacillus polymyxa</i>, <i>Burkholderia pyrrocinia</i> and three <i>Streptomyces</i> isolates. <i>P. chlororaphis</i> and <i>P. polymyxa</i> showed strongest growth inhibition of plant pathogenic <i>Pythium</i> and <i>Fusarium</i> sp., followed by the <i>Streptomyces</i> spp. isolates. 收起
