Abstract
SUMMARY: The aeration of culture media can be measured in terms of ø L (defined below) which is dependent on rate of air flow, agitation, etc. Two methods of measuring ø L are given, based on the polarographic estimation of dissolved oxygen. For penicillin and streptomycin fermentations there is a correlation between the amount of antibiotic produced and ø L.
