title: Transformation of the yeast Trichosporonoides oedocephalis.
abstract: The osmotolerant yeast, Trichosporonoides oedocephalis, is an excellent producer of erythritol, which has wide industrial applications. In this study, we developed an efficient transformation method for T. oedocephalis. To evaluate the T. oedocephalis transformation, we constructed a DNA fragment (loxP-Kan-loxP/Cre system) that was targeted to the mitogen-activated protein kinase HOG1 gene. Transformants were selected on plates containing G418 and response surface methodology was employed to obtain optimum transformation conditions. Optimal transformation could be achieved at an incubation time of 40 min, when the concentration of zymolyase-100T was 30 µg/mL, and when 100 mM CaCl2 was added to the mixture. The predicted optimal transformation efficiency was 133 transformants per µg of DNA. This novel method will facilitate studies in synthetic biology and metabolic engineering of T. oedocephalis.
