“…They were able to utilize methanol as the sole source of carbon. These characters are typical for the genus Ogataea (Yamada et al, 1994). Only delayed and very weak growth was observed in repeated nitrate assimilation tests of the three strains; thus, it was difficult to give a clear interpretation of the results.…”

“…Based on partial sequence analysis of small (18S) and large (26S) subunit rRNA genes, Yamada et al (1994) proposed the genus Ogataea to accommodate a group of yeast species formerly classified in the genus Pichia. The species included in Ogataea were characterized by forming hat-shaped ascospores and utilizing methanol and nitrate as sole sources of carbon and nitrogen, respectively (Yamada et al, 1994;Mikata & Yamada, 1995).…”

The genus Ogataea was not accepted by Kurtzman (1998) because of the absence of a more robust dataset to substantiate the circumscription of the genus.…”

Two methanol-assimilating yeast strains were isolated from a flux of a sessile oak (Quercus petrea) in Hungary and one genetically and phenotypically very similar strain from a flux of a red oak (Quercus rubra) in Canada. The strains exhibited ascomycetous affinity but ascospore formation was not observed. On the basis of the sequence of their D1/D2 domain of the large subunit rDNA, as well as of their physiological characteristics, they represent a novel yeast species of the genus Candida. Therefore Candida floccosa sp. nov. is proposed, with NCAIM Y.01581T (=CBS 10307T=NRRL Y-27951T) as the type strain.

Three strains (N002, N069 and PT31 T ) 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 6C and up to a high temperature (37 6C). 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 PT31 T (=BCC 16875 T =JCM 12984 T =CBS 10098 T ).Methanol metabolism is a characteristic shown by relatively few yeast species (the methylotrophic yeasts); most known methylotrophic yeasts belong to the genera Pichia and Candida (Kurtzman & Fell, 1998;Barnett et al., 2000). From the differences in the partial sequences of small-subunit (18S) and large-subunit (26S) rDNA sequence, Yamada et al. (1994) proposed the transfer of hat-shaped ascosporeforming, nitrate-assimilating methylotrophic yeast species formerly classified in the genus Pichia (Pichia angusta, Pichia minuta var. minuta, P. minuta var. nonfermentans, Pichia philodendra, Pichia glucozyma and Pichia henricii) to a newly described genus, Ogataea. Thereafter, Mikata & Yamada (1995) transferred Pichia kodamae to the genus Ogataea.Recently, Morais et al. (2004) described Ogataea falcaomoraisii as a novel sporogenous methylotrophic yeast, on the basis of the sequences of the D1/D2 domain of the 26S rDNA. However, the circumscription of Ogataea is not generally accepted. Kurtzman & Robnett (1998) suggested that a more robust dataset is required in order to substantiate the circumscription.Methylotrophic yeasts have attracted interest since they were first isolated for both physiological study and industrial applications (Levine & Cooney, 1973;Demain et al., 1998). Recently, some of them have become the principal biocatalyst for the production of useful compounds, and are an important host for the expression of genes (Sakai et al., 1996;Gellissen, 2000). Thermotolerant or thermophilic micro-organisms have certain advantage...
