A simple device of an improvised fermentor for production of rhizobial culture.
A simple new batch fermentor, suitable for both laboratory and industrial small scale cultivation of micro-organisms, particularly rhizobia, was designed and constructed. It was found to operate as a conventional stirring tank reactor. The device reliably ensures the sterility of cultivation, irrespective of its duration. Its installation costs are relatively low, it does not show a high consumption of energy for stirring, the operation is very simple and does not require maintenance of complicated equipment. On this basis, a procedure of design for this fermentor is outlined over the more complex scale up problems of a tank fermentor.
