Indretning og fremgangsmåde til fremstilling af biologisk aktive forbindelser ved hjælp af fermentering

摘要

The present invention relates to a process and an apparatus for the fermentational production of biologically active materials, wherein a fermenter is located in an insulator which, in turn, is located within a working chamber or is adjacent to it. A pressure gradient in relation to ambient pressure prevails in both the insulator and in the working chamber.
