A note on the presence of novel DNA species in the spoilage yeasts Zygosaccharomyces bailii and Pichia membranaefaciens.
Two novel covalently closed circular DNA species of 5.4 and 6.0 kilobases were detected in strains of Zygosaccharomyces bailii with a rapid small scale isolation procedure. The 5.4 kb species was found in four strains and both species were found in three strains. A novel, covalently-closed circular DNA species of 6.9 kb was detected in four of 12 strains of Pichia membranaefaciens . Plasmid DNA (2 micron) (that is CCC DNA of approximately 6 kb in Saccharomyces cerevisiae) was detected in 38 of 40 strains of Sacch . cerevisiae confirming reports of the widespread distribution of this plasmid.
