A new device is designed that is suitable for both laboratory‐ and industrial‐scale cultivation of microorganisms, particularly filamentous fungi, on the surface of liquid media. The device reliably ensures the sterility of cultivation, regardless of its duration. Its installation costs are relatively low and maximum production is reached per unit of installation space. In comparison with submerged cultures in fermentors, the proposed mode does not use a high consumption of energy for stirring and aeration (consequently, the duration of cultivation is not an economically relevant factor) and does not require maintenance of complicated equipment. Due to the building and construction of the technological equipment, the production plant is capable of very fast expansion and, when the need arises of very fast and economical liquidation.
