The cells may grow and escape, and therefore may be in equilibrium with free cells in suspension [8,9].Apart from the ease of the immobilization technique, which can be achieved by simple contact of a cell suspension with the carrier fora time period, TC has a number of other advantages such as food grade purity, availability all-year-round, suitability for extremely low temperature fermentations and production of bio-processed products with improved quality [9,11].
