Abstract
In a semicontinuous process immobilized Claviceps paspali mycelia prod uced alkaloids over a period of 60 days (six reincubations). By additi on of the surfactant Pluronik, a polyethoxypolypropoxy polymer, a cons iderable increase in alkaloid biosynthesis occurred. The maximum produ ct concentration achieved was 8.35 g l(-1), and the overall productivi ty was 5.80 mg l(-1) h(-1), which is half the productivity of the batc h process. Maximum process productivity for a single reincubation (12. 3 mg l(-1) h(-1)) was almost equal to the batch process productivity.
