Changes in Respiratory Capacity and the Loss of Acid-fastness During Yeast Ascospore Germination

Abstract

<p>Experiments are described which investigate the effect of some nutritional and environmental factors on the germination of yeast ascospores. The factors stressed are the carbon and nitrogen sources and the gaseous environment. Loss of acid-fastness and changes in respiratory activity are investigated for their suitability as germination criteria.</p> <p>In the discussion, the respiratory features of the three major phases in the life cycle of yeast, that is, growth, sporulation, and germination, are compared.</p>
