Abstract
The social amoeba Dictyostelium discoideum is amenable to cultivation in the immobilised state most simply by colonisation of porous supports. An analysis of the growth behaviour of D. discoideum in the immobilised state is reported. For this purpose, D. discoideum was cultivated in continuously operated reactors in a suspension culture (homogeneous system) and immobilised on a porous support (heterogeneous system). Thus, it is possible to compare homogeneous and heterogeneous systems under steady-state conditions. Immobilisation was achieved by the colonisation of porous glass beads (SIRAN). Simple models are applied in order to describe the growth behaviour of fractions of both the cells in free suspension and the cells inside the porous carrier. This analysis shows that D. discoideum inside the pores grows at a rate of only about 10% compared with that in free solution. The consequence of this behaviour is discussed in terms of reactor performance.
