Cyberlindnera xishuangbannaensis f.a., sp. nov., a yeast isolated from rotting wood

Three strains representing a novel species of yeast were isolated from samples of rotting wood collected from Xishuangbanna Tropical Rainforest in Yunnan Province, PR China. Phylogenetic analysis based on the concatenated sequences of the internal transcribed spacer (ITS) region and the D1/D2 domains of the large subunit (LSU) rRNA gene revealed that the novel species is a member of the genus Cyberlindnera, although the formation of ascospores was not observed. The novel species was related most closely to the type strain of the species Candida pattaniensis, but they had a 0.5 % sequence divergence (3 substitutions, 0 gap) in the D1/D2 domain and a 5.4 % sequence divergence (21 substitutions, 10 gaps) in the ITS region. The novel species could also be differentiated from the closely related species by some biochemical and physiological characteristics. The species name Cyberlindnera xishuangbannaensis f.a., sp. nov. is proposed to accommodate these strains, with NYNU 16752 T (=CICC 33163 T =CBS 14692 T ) designated as the type strain. The MycoBank number is MB 822199.
