“…In a fluidised-bed reactor, it was found that the free amino nitrogen (FAN) uptake by entrapped yeast cells increased linearly with the superficial velocity of the wort in the reactor. 35,40 This relationship has also been found in a gas-lift bioreactor. 41 The rate of amino acid uptake in the fluidised-bed reactor was very similar to that of a free-cell system.…”

Immobilised cells are increasingly being used in bio-industries and may also have benefits for the brewing industry. The major challenge to applying this technology successfully in breweries is focused on the main fermentation in combination with the secondary fermentation. In particular, the control and fine-tuning of the flavour profile during the main fermentation require further investigation. In this review, the influence of immobilised cell technology on the production of the flavour-active compounds (i.e. higher alcohols, esters and vicinal diketones) is discussed. Control strategies that are based on the manipulation of parameters during fermentation such as temperature, feed volume, wort gravity, wort composition and aeration are explained. Finally, bioreactor configurations that may facilitate immobilised cells in performing the primary fermentation are evaluated.

“…Yeast immobilisation is known to influence the cellular metabolism. which can be positive or negative with regard to beer production (Masschelein et al 1994;Norton and D'Amore 1994;van Iersel et al 2(00). For accelerated maturation during the secondary beer fermentation, as well as for dietetic and alcoholfree beer, large-scale production with carrier-fixed yeast cells are sporadically carried out (van Iersel et al 1998).…”

“…Furthermore, employing immobilised yeasts allows using yeast strains regardless their flocculant characteristics, since only flocculant strains are suitable for the classical beer fermentation. Various aspects of immobilised cell technology in brewing industry were reviewed by Masschelein et al (1994).…”

We studied the influence of immobilised yeasts on fermentation parameters and beer quality using a continuous gas-lift bioreactor system with Saccharomyces warum entrapped in calcium pectate beads. The higher the amount of biomass, the shorter the fermentation time. At an immobilised biomass volume to wort ratio of 0.35:1 (v/v), productivity began to fall and the specific rate of saccharide utilisation decreased. The optimum level for productivity and beer quality was obtained at the ratio of 0.27:1 (v/v) biocatalyst volume to the wort volume. Beer with suitable flavour, low level of diacetyl (less than 0.1 mg/1) and an optimum ratio of the higher alcohols to esters content (4.53:1) has been produced with a residence time of 13.16 h 123
