Effect of carbon dioxide on growth and extracellular enzyme production by Pseudomonas fluorescens B52.
The effect of carbon dioxide (30 mM.l-1) on growth and extracellular protease and lipase production by Pseudomonas fluorescens B52 growing in a simulated milk medium at 7 degrees C in fermenter was investigated. The addition of carbon dioxide was shown to have a differential effect with extracellular enzyme production, particularly lipase, being inhibited to a greater extent than bacterial growth and final cell numbers.
