High Cell Density Cultivation of Pseudomonas putida BM01 Using Glucose

Pseudomonas putida BM01 was grown efficiently on glucose as the sole carbon source with a supply of a nitrogen source in pH-stat mode using a low setpoint limit. A final cell concentration of 100 g/l was obtained in 30 h of fed-batch cultivation by controlling glucose concentration within the range of 5-20 g/l and maintaining dissolved oxygen tension above 10$%$ saturation using pure oxygen. This high cell density culture technique is believed highly useful for the production of poly(3-hydroxyalkanoates) by this strain.
