Title Improvement of Oil Degradation and MEL Production in a Yeast Strain, Pseudozyma tsukubaensis, by Translation Elongation Factor 1 Promoter-driven Expression of a Lipase.
Journal J Oleo Sci
Abstract The basidiomycetous yeast Pseudozyma tsukubaensis produces a mannosylerythritol lipid (MEL) homologue, a diastereomer type of MEL-B, from olive oil. In a previous study, MEL-B production was increased by the overexpression of lipase PaLIPAp in P. tsukubaensis 1E5, through the enhancement of oil consumption. In the present study, RNA sequence analysis was used to identify a promoter able to induce high-level PaLIPA expression. The recombinant strain, expressing PaLIPA via the translation elongation factor 1 alpha/Tu promoter, showed higher lipase activity, rates of oil degradation, and MEL-B production than the strain which generated in our previous study.
