Development of a fluid-bed coating process for soil-granule-based formulations of Metarhizium brunneum, Cordyceps fumosorosea or Beauveria bassiana.

Aim: Granule-based products of solid state fermented micro-organisms are available for biocontrol. Because liquid fermentation has several advantages, we investigated fluid-bed coating with liquid fermented biomass.

Methods And Results: Biomass containing mycelium or mycelium and submerged spores of the entomopathogenic fungi Metarhizium brunneum, Cordyceps fumosorosea and Beauveria bassiana were produced in liquid culture, separated and different biomass concentrations were adjusted.
