    Hollow fibre modules as membrane reactor in biocatalysis (1992)
    Berlin : Wiley-Blackwell
    Acta Biotechnologica 12 (1992), S. 133-142

    Notes: As shown in the case of the enzymatic cleavage of Penicillin G by Penicillin acylase hollow fibre modules of the type MLW (molecular separation value of 10,000 Dalton) produced for blood dialysis are also suitable as membrane reactor.The enzymes physically bound in the hollow fibre allow a reproducible reaction rate and are characterized by an acceptable stability.The studies indicate an operating stability which makes possible low production costs of amino penicillin acid.

    Ultrafiltration of enzyme solutions by means of blood dialyzers (1992)
    Berlin : Wiley-Blackwell
    Acta Biotechnologica 12 (1992), S. 143-153

    Notes: Hollow fibres with a symmetrical pore structure as used in artifical kidneys are tested for other purposes. The modules are shown to be suitable for the processing of enzymes such as thermitase, penicillin acylase, uratoxidase, and phosphatase by means of ultrafiltration and diafiltration.These hollow fibre modules are compared with other modules used in laboratory or in small technical devices. Similar values and material transfer coefficients are calculated.
