Abstract
A new method has been developed to increase the productivity of aspergilli - producers of extracellular proteinases based on their cultivation on vermiculite under solid-state fermentation conditions. The productivity of the mycelium Aspergillus ochraceus L-1 and Aspergillus ustus 1 was 3-18 times higher not only in comparison with submerged cultivation, but also in comparison with growth on other carriers studied under solid-state fermentation conditions. Vermiculite can be considered as a new promising carrier for solid-state fermentation of micromycetes.
