Further progress toward its solution would appear to depend upon an extension of our knowledge of the effects produced by air on the growth phases of facultative bacteria; for whether theories are based on oxidative inhibition of fermentation or on stimulation of aerobic processes permitting abundant growth, account must be taken of the fact that, although some workers have reported increased growth of heterotrophs, others have observed growth suppression. Thus Lwoff and Monod (1947) found that such bacteria, grown without lag in test tubes, showed prolonged lag in flasks aerated by agitation at normal CO2 tensions, but in contrast Winslow, Walker, and Sutermeister (1932) for
