Candida ficus sp. nov., a novel yeast species from the gut of Apriona germari larvae.
A novel yeast species is described based on three strains from the gut of wood-boring larvae collected in a tree trunk of Ficus carica cultivated in parks near Nanyang, central China. Phylogenetic analysis based on sequences of the D1/D2 domains of the large subunit rRNA gene showed that these strains occurred in a separate clade that was genetically distinct from all known ascomycetous yeasts. In terms of pairwise sequence divergence, the novel strains differed by 15.3% divergence from the type strain of Pichia terricola, and by 15.8% divergence from the type strains of Pichia exigua and Candida rugopelliculosa in the D1/D2 domains. All three are ascomycetous yeasts in the Pichia clade. Unlike P. terricola, P. exigua and C. rugopelliculosa, the novel isolates did not ferment glucose. The name Candida ficus sp. nov. is proposed to accommodate these highly divergent organisms, with STN-8(T) (=CICC 1980(T)=CBS 12638(T)) as the type strain.
