Summary
The sporulation of the fungus Claviceps purpurea is connected with the change in its respiration rate which is effected by deficiency of dissolved oxygen tension. It stops the vegetative growth of the fungus and induces the formation of conidiophores with conidia production until glucose is exhausted. With exhaustion of glucose the conidiophores continue to produce conidia by transforming vegetative cell material into conidia. Therefore final conidial concentration in batch fermentation depends on these two processes which can be regulated by oxygen input.
