Two strains (S-34T and S-35) of a novel ascomycetous yeast species belonging to the genus Kazachstania were isolated from soil from a mixed deciduous forest in Amphoe Wang Nam Khiao, Nakhon Ratchasima Province, Thailand. The D1/D2 domains of the large-subunit rDNA sequences of the two strains were identical and also indicated a close relationship with respect to Kazachstania aquatica, Kazachstania unispora, Kazachstania aerobia, Kazachstania servazzii and Kazachstania solicola. The most closely related species, K. aquatica, has 14 nucleotide substitutions and three gaps in 566 nt. The phenotypic characteristics of the two strains were typical of those of members of the genus Kazachstania. These characteristics include the formation of a single globose ascospore in an unconjugated and persistent ascus, multilateral budding, the absence of arthrospores and ballistospores, the fermentation of glucose, the inability to assimilate nitrate, negative diazonium blue B and urease reactions, and the presence of ubiquinone Q-6. The novel strains can be distinguished from K. aquatica on the basis of a number of phenotypic characteristics and represent a novel species in the genus Kazachstania, for which the name Kazachstania siamensis sp. nov. is proposed. The type strain is S-34T (=CBS 10361T=NBRC 101968T=BCC 21230T).

Six strains of a novel yeast species were isolated from Nothofagus species trees in native forests in Patagonia, Argentina. The strains were isolated from bark, fluxes and the ectomycorrhizospheric soil fraction of Nothofagus antarctica, Nothofagus nervosa and Nothofagus pumilio. Analysis of the D1/D2 large-subunit rDNA sequences indicated that the novel species belonged to the genus Lachancea and is closely related to Lachancea meyersii. The name Lachancea nothofagi sp. nov. is proposed to accommodate these strains. The type strain is UWOPS 99-807.3T (=CBS 11611T=NRRL Y-48670T).

Three strains (N002, N069 and PT31T) of a novel thermotolerant methylotrophic yeast species belonging to the genus Pichia were isolated from soil collected in Thailand by three consecutive enrichments in methanol broth at room temperature. They were categorized as thermotolerant strains on the basis of their good growth below 20 °C and up to a high temperature (37 °C). The major characteristics of the three strains included the following and placed them in the genus Pichia: the formation of four helmet-/hat-shaped ascospores in a deliquescent ascus that might be unconjugated or produced by conjugation between a cell and its bud or between independent cells; multilateral budding; the presence of ubiquinone Q-7; negative for Diazonium blue B colour and urease reactions; and the absence of arthrospores and ballistospores. The three strains differed by one to three nucleotide substitutions in the sequences of the D1/D2 domain of the large-subunit rDNA sequence. Phylogenetic analysis revealed that their closest species was Pichia dorogensis, but with 11–13 nucleotide substitutions in 554 nt. The phenotypic characteristics of the three strains were the same. The strains could be distinguished from P. dorogensis by a number of phenotypic characteristics. On the basis of the above findings, these three strains were assigned to a single novel species of Pichia, for which the name Pichia thermomethanolica sp. nov. is proposed. The type strain is PT31T (=BCC 16875T=JCM 12984T=CBS 10098T).

Two xylose-utilizing yeast strains isolated from rotten wood collected in the rainforest in different mountains of Hainan province, southern China, were studied. Sequence analysis of the large subunit rDNA D1/D2 domain and internal transcribed spacer region revealed that the strains represent a novel anamorphic yeast species, for which the name Candida cellulosicola sp. nov. is proposed; the type strain is HNX16-2T ( = CGMCC 2.3503T = CBS 11952T). Phylogenetically, the novel species was closely related to a xylose-utilizing teleomorphic ascomycetous yeast species Spencermartinsiella europaea in the family Trichomonascaceae, but differed from the latter by 3.0 % mismatches in the D1/D2 domain.

Six strains representing a novel yeast species belonging to the genus Saturnispora were isolated from two species of the Drosophila fasciola subgroup (Drosophila repleta group) in an Atlantic rainforest site in Rio de Janeiro State, Brazil. Four strains were isolated from crops and one from external parts of Drosophila cardinae. The other strain was isolated from external parts of Drosophila fascioloides. Analysis of the D1/D2 large-subunit rDNA sequences indicated that the novel species is closely related to Saturnispora dispora. The name Saturnispora hagleri sp. nov. is proposed to accommodate these strains. The type strain is UFMG-55T (=CBS 10007T=NRRL Y-27828T).

Additional Strain

During a study of yeast diversity in Azorean vineyards, four strains were isolated which were found to represent a novel yeast species based on the sequences of the internal transcribed spacer (ITS) region (ITS1-5.8S–ITS2) and of the D1/D2 domain of the large subunit (LSU) rRNA gene, together with their physiological characteristics. An additional strain isolated from Drosophila suzukii in Italy had identical D1/D2 sequences and very similar ITS regions (five nucleotide substitutions) to the Azorean strains. Phylogenetic analysis using sequences of the ITS region and D1/D2 domain showed that the five strains are closely related to Clavispora lusitaniae, although with 56 nucleotide differences in the D2 domain. Intraspecies variation revealed between two and five nucleotide differences, considering the five strains of Clavispora santaluciae. Some phenotypic discrepancies support the separation of the new species from their closely related ones, such as the inability to grow at temperatures above 35 °C, to produce acetic acid and the capacity to assimilate starch. Neither conjugations nor ascospore formation were observed in any of the strains. The name Clavispora santaluciae f.a., sp. nov., is proposed to accommodate the above noted five strains (holotype, CBS 16465T; MycoBank no., MB 835794).

Six strains of a novel yeast species were isolated from tree bark collected in the Atlantic Forest and the Amazon Rainforest in Brazil. Analyses of the sequences of D1/D2 domains of the large subunit rRNA gene showed that the strains belong to a species in the genus Zygotorulaspora. The species differed by 5.54 % sequence divergence (25 substitutions and five indels out of 542 bp) in the D1/D2 sequences from Zygotorulaspora mrakii, its closest relative. The ITS sequence of the type strain of the novel species differs by 27–69 nucleotide substitutions/indels from the other Zygotorulaspora species. The novel species is able to grow on trehalose, maltose, l-sorbose, inulin and at 37 °C, which are negative in Z. mrakii. The name Zygotorulaspora cariocana sp. nov. is proposed. The holotype of Z. cariocana sp. nov. is CBS 16118T. The MycoBank number is MB 833702.

Two isolates of a novel yeast species were obtained from water tanks (phytotelmata) of the bromeliad Vriesea minarum collected in a tableland (‘campo rupestre’) ecosystem in Brazil. The sequences of the D1/D2 domains of the large-subunit rRNA gene showed that this species is related to Kazachstania exigua and others, from which it differs by 8–10 nucleotide substitutions. The novel species Kazachstania rupicola sp. nov. is proposed to accommodate these isolates. The type strain is UFMG-BRO-80T ( = CBS 12684T  = CBMAI 1466T).

During an investigation of yeast biota in the rhizosphere of lentisk in Sardinian semi-arid areas, a strain was isolated that could not be assigned to any known species. The sequence of the D1/D2 domain of the large subunit rDNA gene revealed that the strain belonged to the genus Kazachstania and was phylogenetically related to a clade including Kazachstania aerobia, Kazachstania servazzii, Kazachstania solicola and Kazachstania unispora. The novel isolate differed from members of this clade in its ability to assimilate d-glucono-1,5-lactone and its very weak fermentation of glucose and sucrose; its assimilation profile was unique within the genus Kazachstania. Monosporal colonies were able to sporulate, indicating that the species is homothallic. It is proposed that the isolate represents a novel species, Kazachstania ichnusensis sp. nov., with LCF 1675T ( = CBS 11859T) as type strain.

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.
