Coated Solid Substrate Microbe Formulations: Pseudomonas spp. and Zeolite

: Formulation provides a means to stabilize for storage and delivery biocontrol and bioremediation agents based on microbes such as bacteria and fungi. Typically it is difficult to both stabilize and deliver fragile non-spore-forming bacteria. Fungal spores might intuitively appear to be easy to stabilize; however, their tendency to germinate in low moisture environments presents challenges for the formulation scientist. Here we present a light background regarding issues with formulating microbes and strategies to help overcome instability and delivery issues.
