In this particular strain, filamentous cells ( F forms) predominate during the initial stages of aerobic propagation whilst budding yeast cells ( Y forms) predominate during anaerobiosis. In other K . marxianus strains, and in Candida pseudotropicalis, budding cells predominate irrespective of oxygen availability. Increase…
