Abstract

SUMMARY: Young colonies of two swarming organisms, and grew about as quickly on solid media as in liquid culture whilst four non-swarming organisms, and all grew slower on solid than in liquid media. Oxygen uptake by young colonies of followed manometrically, increased exponentially at about the same rate as unrestricted aerobic growth. All other colonies demonstrated accelerating respiration which was either not strictly exponential or, in the case of definitely biphasic, with a fast then a slow exponential rate of increase. Actual and potential respiration was determined for each species by measuring oxygen uptake before and after resuspending the colony in liquid medium. The ratio of actual to potential respiration was largest in the flat, spreading and smallest in the small, hemispherical Calculations suggest that oxygen penetrates between 3I and 4I μm into colonies of and and only 9 μm into colonies of
