Inventor: VOJTISEK VLADIMIR DR
IPC: C12P37/06
Filed: 1978-11-16
Abstract: New immobilised penicillin acylase for conversion of penicillins (esp. benzyl-penicillin) into 6-aminopenicillanic acid(6-APA) consists of the enzyme penicillin acylase and cells or cell fragments of prokarionts or eukaryonts chemically bound to each by means of polyfunctional aldehydes, pref. glutaraldehyde. Used in the prodn. of 6-APA, which in turn is useful in the prodn. of semisynthetic pencillins. The cells used as carriers for the immobilisation are inexpensive and, since chemical activation is not required, the immobilisation process is simple. Immobilised penicillin acylase preparations with very high specific activity can be produced. If the cells used are those of penicillin acylase-producing organisms, expensive purification of the enzyme can be avoided.

Title: Radioactive sewage decontamination - by settling and mineralising before digestion and decay, and final filtering
Inventor: SCHULZ WERNER
IPC: G21F9/12
Filed: 1979-03-14
Abstract: A plant for the decontamination of radioactive effluents of short half-life, for example the sewage of hospitals and stations of the nuclear medicine, is based on a combined processing by settling and filtering. The sewage is passed through settling and mineralising tanks where most of the radioactive sludge is deposited. This is drawn off and allowed to decay in separate tanks. The remaining fluid is passed via a buffer tank to a filter battery. This concentrates the decay process on the radioactive components (iodine) and retains any residual iodine in the filter cartridges, so that the space required for the plant is reduced.
