Bud Formation in Saccharomyces cerevisiae and a Comparison with the Mechanism of Cell Division in Other Yeasts

Abstract

SUMMARY: A study of the ultrastructural characteristics, the physiological properties and an analysis of hydrolysates of phenol-treated cell walls of Corynebacterium rubrum were made. While the arabinogalactan-peptidoglycan complex found in the cell-wall hydrolysates was that common to the genera Corynebacterium, Mycobacterium and Nocardia, the ultrastructural patterns found, the physiological reactions observed, the sensitivity to nocardiophages but not to corynebacteriophages or mycobacterial phages, and the (previously reported) presence of nocardomycolic acids, combined with the absence of corynemycolic acids and mycolic acids, indicate that this species belongs in the genus Nocardia rather than in the genus Corynebacterium.
