Abstract
During laboratory experiments on the effect of different gaseous atmospheres on the microflora of unpasteurized beer in metal casks, some anomalous results appeared when using pure oxygen. Investigation shows that oxygen tension at a sufficiently high level can inhibit and restrict the growth of a large number of micro-organisms capable of occurring in beer, and this effect is due to the oxygen and not to the pressure.
