Among ascomycetous yeasts that were isolated from several nature reserve areas in China, three anamorphic strains isolated from soil (QL 5-5T) and fruit (QL 21-2T and SN 15-1T) were revealed, by conventional characterization and molecular phylogenetic analysis based on internal transcribed spacer and large subunit (26S) rRNA gene D1/D2 region sequencing, to represent three novel species in the genus Candida. Candida qinlingensis sp. nov. (type strain, QL 5-5T=AS 2.2524T=CBS 9768T) was related closely to a teleomorphic species, Williopsis pratensis. The close relatives of Candida diospyri sp. nov. (type strain, QL 21-2T=AS 2.2525T=CBS 9769T) are Candida friedrichii and Candida membranifaciens. Candida asparagi sp. nov. (type strain, SN 15-1T=AS 2.2526T=CBS 9770T) forms a clade with Candida fructus.

In the course of an on-going study aimed at cataloguing the natural yeast biodiversity found in Ecuador, two strains (CLQCA 13-025 and CLQCA 20-004T) were isolated from samples of cow manure and rotten wood collected in two separate provinces of the country (Orellana and Bolívar). These strains were found to represent a novel yeast species based on the sequences of their D1/D2 domain of the large-subunit (LSU) rRNA gene and their physiological characteristics. Phylogenetic analysis based on LSU D1/D2 sequences revealed this novel species to belong to the Metschnikowia clade and to be most closely related to Candida suratensis, a species recently discovered in a mangrove forest in Thailand. The species name of Candida ecuadorensis sp. nov. is proposed to accommodate these strains, with strain CLQCA 20-004T ( = CBS 12653T = NCYC 3782T) designated as the type strain.

Wood Boring

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-8T ( = CICC 1980T = CBS 12638T) as the type strain.

Thirteen strains of yeasts were isolated from ambrosia beetle galleries at several sites in Japan. Based on the morphological and biochemical characteristics and phylogenetic analysis of the D1/D2 domain of the large subunit (LSU) rRNA gene of the yeasts, 10 strains were shown to represent a novel species of the genus Wickerhamomyces, described as Wickerhamomyces scolytoplatypi sp. nov. (type strain NBRC 11029T = CBS 12186T), and were closely related to Wickerhamomyces hampshirensis. The three other strains represented a novel species of the genus Cyberlindnera, described as Cyberlindnera xylebori sp. nov. (type strain NBRC 11048T = CBS 12187T), and were closely related to Cyberlindnera euphorbiiphila. It is suggested that these species are associated with ambrosia beetles and we consider ambrosia beetle galleries as good sources of novel yeasts.

Eight strains of a novel yeast species were isolated from tree saps of ‘Coihue’ (Nothofagus dombeyi, Nothofagaceae) and glacial meltwater (Castaño Overo River) in the Nahuel Huapi National Park, Patagonia, Argentina. The sequences of the D1/D2 domains of the large subunit of the rRNA gene showed that this novel yeast species belongs to the Wickerhamomyces genus (Order Saccharomycetales, Family Wickerhamomycetaceae). The closest related species were Candida ponderosae and Wickerhamomyces chambardii. Wickerhamomyces patagonicus sp. nov. is proposed to accommodate these novel strains, with the type strain CRUB 1724T (=CBS 11398T =JCM 16381T).

In an investigation of the yeast biota involved in silage deterioration, a considerable number of strains belonging to Saccharomyces and related genera were isolated from aerobically deteriorating corn silage in Tochigi, Japan. Analysis of sequences of the internal transcribed spacer and the large-subunit rRNA gene D1/D2 domain and electrophoretic karyotyping indicated that two of the strains, NS 14T and NS 26, represent a novel species with close phylogenetic relationships to Kazachstania servazzii and Kazachstania unispora. It is proposed that the novel species be named Kazachstania aerobia sp. nov., with NS 14T (=AS 2.2384T=CBS 9918T) as the type strain.

Two novel yeast species, Candida aechmeae sp. nov. and Candida vrieseae sp. nov., were isolated from bromeliads in Itapuã Park, Rio Grande do Sul, Brazil. These species are genetically isolated from all other currently recognized ascomycetous yeasts based on their sequence divergence in the D1/D2 domain of the LSU rRNA gene. C. aechmeae sp. nov. is phylogenetically close to Candida ubatubensis, a species also isolated from bromeliads in Brazil, but the novel species can be differentiated on the basis of differences in the D1/D2 domain and positive results for the assimilation of l-arabinose, raffinose, inulin and citrate. Candida vrieseae sp. nov. is phylogenetically placed in a clade near Candida membranifaciens that is composed of several species associated with insects, but the novel species can be differentiated from them by the D1/D2 and ITS gene sequences, positive results for the assimilation of nitrite and a negative result for the assimilation of ethylamine. The type strain for Candida aechmeae sp. nov. is BI153T (=CBS 10831T=NRRL Y-48456T) and the type strain for C. vrieseae sp. nov. is BI146T (=CBS 10829T=NRRL Y-48461T).

Mango Leaves

Five strains of a novel methanol-assimilating yeast species were isolated from mango (Mangifera indica) leaves collected at the campus of the Federal University of Minas Gerais in Brazil. The sequences of the internal transcribed spacer (ITS) region and the D1/D2 domains of the large subunit of the rRNA gene showed that this species belongs to the Ogataea clade and is related to O. allantospora, O. chonburiensis, O. dorogensis, O. kodamae, O. paradorogensis and Candida xyloterini (Ogataea clade). The novel species differs in the D1/D2 domains of the large subunit of the rRNA gene by 12 to 40 substitutions from these Ogataea species. The name Ogataea mangiferae sp. nov. is proposed for this novel species. The type strain of Ogataea mangiferae sp. nov. is UFMG-CM-Y253T ( = CBS 13492T). The Mycobank number is MB 811646.

Two strains isolated from rotten wood were included in the Saccharomyces group based on morphological characteristics. However, rRNA gene sequence analyses (including the 18S rRNA gene, 26S rRNA gene D1/D2 domain and internal transcribed spacer region) indicated that these two strains represent a novel species of Naumovozyma, for which the name Naumovozyma baii sp. nov. is proposed (type strain: BW 22T = CGMCC 2.04520T = CBS 12642T). The MycoBank number of the new species is MB800484.

Nine methanol-assimilating yeast strains isolated from olive oil sediments in Slovenia, extra virgin olive oil from Italy and rotten wood collected in Hungary were found to form three genetically separated groups, distinct from the currently recognized yeast species. Sequence analysis from genes of the small subunit (SSU) rRNA, internal transcribed spacer region/5.8S rRNA, large subunit (LSU) rRNA D1/D2 domains and translational elongation factor-1α (EF-1α) revealed that the three closely related groups represent three different undescribed yeast species. Sequence analysis of the LSU rRNA gene D1/D2 domains placed the novel species in the Ogataea clade. The three novel species are designated as Ogataea kolombanensis sp. nov. (type strain: ZIM 2322T = CBS 12778T = NRRL Y-63657T), Ogataea histrianica sp. nov. (type strain: ZIM 2463T = CBS 12779T = NRRL Y-63658T) and Ogataea deakii sp. nov.

Five strains of a novel yeast species were isolated from rotting wood samples collected in an Amazonian forest site in the state of Roraima, northern Brazil. The sequences of the D1/D2 domains of the large subunit of the rRNA gene showed that this species belongs to the Scheffersomyces clade and is related to Candida coipomoensis, Candida lignicola and Candida queiroziae. The novel species Candida amazonensis sp. nov. is proposed to accommodate these isolates. The type strain of C. amazonensis sp. nov. is UFMG-HMD-26.3T ( = CBS 12363T = NRRL Y-48762T).
