Title: Obtaining useful energy from a flowing stream
Inventor: DICKENS WILLIAM RICHMOND
IPC: F03B17/00
Filed: 1982-12-08
Abstract: Parallel cylindrical bars 7 are mounted with their axes horizontal in a frame 4, 5 which is itself then mounted within a stream of flowing liquid so that the cylinder axes lie transverse to the flow. The movement of the stream over the cylinders causes the frame to oscillate, under elastic restraint, in a third direction which lies normal both to the flow and to the cylinder axes.

Abstract: Attenuated strains of Listeriosis monocitogenes deposited in "NBPMKK" under numbers 251 and 252 are cultivated on meat-peptone bouillon in a fermenter, the bouillon containing 8-20 g/l glucose. Cultivation is at 35-37 DEG C and pH from 7 to 7.6, with air passed through preferably at 3-5 l/min, and a stirrer operated at 300 to 1000 r.p.m. The amount of innoculum is from 1:20 to 1:100 of the working volume of the fermenter. After termination of the cultivation, depending on the density of the biomass obtained, the latter is diluted with protective medium and then it may be homogenised and lyophilised. A biomass having a density of 12 milliard/ cm<3> living bacterial cells may be obtained. For lyophilising of the vaccine, a protective medium containing 2 to 17% by weight sodium glutamate, 5 to 20% saccharose and 0.5 to 5% by weight denatured gelatine is presently used.
