Abstract

The invention relates to a process for the preparation of colorants and/or active compounds by culturing a microorganism of the genus Monascus in a sterilizable fluidized-bed fermenter of low water content, such as was proposed in German Patent Application P 3,625,698.6. The fluidizable particle used here is the microorganism itself--in pellet form or grown on carriers--which can be supplied with nutrients by spraying in substrate solutions. The colorants and/or active compounds are isolated by extraction with organic solvents.
