Pseudozyma jejuensis sp. nov., a novel cutinolytic ustilaginomycetous yeast species that is able to degrade plastic waste.
An ustilaginomycetous anamorphic yeast, isolated from orange leaves on Jeju island in South Korea, represents a novel Pseudozyma species according to morphologic and physiologic findings and molecular taxonomic analysis using the D1/D2 domains of the large subunit (26S) rRNA gene and the internally transcribed spacer (ITS) 1+2 regions. The name Pseudozyma jejuensis sp. nov. is proposed for this novel species, with OL71(T) (=KCTC 17482(T)=CBS 10454(T)) as type strain. In the present study, we have also demonstrated that Pseudozyma jejuensis OL71 is capable of producing cutinase and degrading polycaprolactone. These results suggest that Pseudozyma jejuensis or its cutinase may be useful for the biological degradation of plastic waste.
