摘要: Abstract Citric and isocitric acid production were measured in strain A-101 of Yarrowia lipolytica . Product yield on n-hexadecane, including substrate used for cell growth, was the range 1·08–1·44 g total acid/g n-hexadecane. The citric fraction acids synthesized by a particular subculture 54–64%. Mutants Y. incapable growth citrate isolated at low frequency extremely unstable. difficulty due to ploidy our as confirmed determination nuclear DNA content, average diameter, UV inactivation kinetics. Some mutants also that excreted predominantly when grown
