Notizen:
The effect of total and oxygen partial pressure on metabolic activities of Methylomonas clara has been investigated in batch and continuous cultivation experiments using a pressurizable airlift loop reactor. At Oxygen partial pressures of more than 1000 mbar growth of M. Clara is retarded and completely inhibited at 1200 mbr. However, after several hours of incubation at elevated oxygen partial pressures, biomass formation is nearly doubled in subsquent continuous operation, Cells pretreated with oxygen are characterized by a change of cytochrome content; they excret carboxylic acids into the medium. The results indicate that, by sparging an aerobic culture intermittently wich pure oxygen, formation of biomass might be enbanced. © 1992 John Wiley & Sons, Inc.
