The use of oxygen uptake rate to monitor discovery of microbial and enzymatic biocatalysts.

Arising from the requirement for discovery of novel biocatalysts with unusual properties, a process was developed which uniquely combines aspects of continuous culture with the measurement of oxygen uptake. This adaptation of the chemostat can be used to facilitate the isolation of a number of microorganisms with desirable properties, particularly those with useful metabolic capabilities and/or enzymes. The technique was also used to provide feedback on the metabolic status of a microbial population and increase the feed flow rate (i.
