Die Wirkung von Natriumnitrit auf Nucleinsäurebasen und ihr Verhältnis zur Inaktivierung von Hefezellen

II. Die Inaktivierung von Saccharomyces- Zellen verschiedenen Ploidiegrades

  • Werner Stein and Ernst-Randolf Lochmann

The inactivation of homozygous yeast strains of different ploidy by NaNO2 was investigated. The influence of pH, concentration of NaNO2, time and temperature of treatment, and ploidy have been studied. On the whole there is a remarkable similarity with certain features of UV-inactivation. A critical comparison with the results of part I of this paper leads to the conclusion that the deamination of DNA-bases is the essential biochemical process which causes the biological inactivation.
