metadata.artigo.dc.description.abstract: γ-Decalactone is a flavour compound that when obtained by biotechnological production using microorganisms is classified as natural. The aim of this study is to evaluate various conditions for γ-decalactone production by tropical yeast strains Yarrowia lipolytica CCMA 0242 and Lindnera saturnus CCMA 0243. The growth of and γ-decalactone production by Y. lipolytica CCMA 0242 were higher in castor oil than in glycerol. γ-Decalactone production in single batch or fed-batch fermentation did not differ significantly. The γ-decalactone production by L. saturnus CCMA 0243 was better at initial pH=5, while the production by Y. lipolytica CCMA 0242 was better at initial pH=6. The yeast L. saturnus CCMA 0243 produced more γ-decalactone than Y. lipolytica CCMA 0242 under the same fermentation conditions. The crude glycerol was not an alternative substrate for γ-decalactone production by Y. lipolytica CCMA 0242. Castor oil at volume fraction of 30% showed better results as a substrate. The strain L. saturnus CCMA 0243 showed better results of γ-decalactone production. This yeast species can be considered an alternative producer of γ-decalactone in biotechnological processes.
