Bioactive components in productions using immobilized biosystems

Many systems have already served as an example of application advantages of immobilized enzymes and cells for complete fermentation. Nowadays, there i s a great interest in using immobilized systems for fermented processes. Th ey have been used on many fields of both food and non-food industry. The ac tual research prefers systems with whole cells to those using pure enzymes. It is also important to know the physiology changes of cells within cheap and regenerable immobilization material. This review concerns biological co mponents used in immobilized biosystems, including enzymes, whole microbial cells, fungi, plant cells and animal tissues. The biocomponents are charac terized and several examples of systems using them are mentioned. Physiolog ical changes of bioactive components in an immobilized state during ferment ation are also discussed. For integrity, brief characterization of immobili zation techniques and practical application are included.
