IPC: C12M1/14
Abstract: 782,329. Bacteria cultivating; fermentation vessels. BIOCHEMIE GES. Oct. 25, 1955 [Dec. 29, 1954], No. 30500/55. Classes 14 (2) and 81 (1). [Also in Group IV (b)] In a process for the production of fermentation products obtainable by surface cultivation of micro-organisms, e.g. tyrothricin and citric acid, wherein fermentation vessels connected in series with respect to the supply of liquid and interconnected by means of overflow devices are enclosed in a container and are sterilized and are thereafter charged with nutrient solution and inoculation material, a steady stream of sterilized air, preferably saturated with water vapour, is then conducted over the fermentation vessels in order to carry out the fermentation, the said stream of air ensuring an undisturbed development of the surface skin of the inoculated nutrient solution, and the fermentation material is finally worked up in manner known per se, if desired after emptying the fermentation vessels into the container. The apparatus comprises a cylindrical container 1 which is closed by a cover 2 and contains fermentation vessels 3 arranged one above the other with overflow devices 4 so that the fermentation vessels can be charged with a predetermined amount of fermentation liquid through supply pipes 30, 31 and 32 fitted in the cover 2. The vessels 3 are arranged on a perforated supporting base 37 in segment-shaped compartments 33, 34 and 35 around a perforated central supporting tube 36 which also serves as an air venting pipe. Air supply pipes 7, 8 and 9, arranged vertically between the wall of the container 1 and the fermentation vessels 3, have air discharge apertures 10 directed towards the container wall which serves as a baffle surface. Additional apertures may be provided at the ends of the pipes 7, 8 and 9 so that the air flows against the cover 2. Alternatively, the pipes 7, 8 and 9 may extend upwardly in the centre of the container, the air discharge apertures being directed towards a centrally disposed vertical pipe serving a discharge pipe for the fermentation gases, the outer wall of this pipe forming the baffle surface. In a further modification, radial air supply pipes fed from vertical main supply pipes have air discharge apertures (a) at their ends, so that the air flows on to the wall of the container, or (b) in those sections of the pipes towards the bottoms of the fermentation vessels, which thereby act as baffle surfaces. The baffle surfaces may also be independent elements serving the sole purpose of dispersing the air stream. The container 1 has an emptying pipe 11 and a valve 12, an air venting pipe 13 with venting valve 14 and manometer 15, two thermometer supports 16, 17 and a jacket 20 on which are arranged fittings 21, 24 for steam heating, fittings 22 and 25 for cooling water, fittings 23 and 26 for circulation water. In Fig. 3 (not shown), the fermentation vessel is shown in association with boilers for nutrient solution and sugar solution, the process of the invention and the operation of the apparatus being illustrated by reference to the production of tyrothricin by Bacillus brevis.
