Abstract
Plant cells (Nicotiana tabacum) were genetically engineered to produce a foreign protein, chloramphenicol acetyltransferase (CAT), and the CAT production from suspension cultures was investigated. Suspension cultures were grown in a shake flask, a stirred fermenter, and a bubble-column fermenter. The CAT production was growth related and the maximum activity was reached during the early stationary phase. A 41-day, semicontinuous stirred fermenter run, consisting of five sequential batch runs, demonstrated long-term CAT production. Continuous CAT production was also accomplished in a bubble-column fermenter at a medium flow rate of 3.1 ml h-1, which was equivalent to a dilution rate of 0.25 day-1.
