Two asexual arthroconidial yeast strains, TM3-44T and LYSM5T, were isolated, respectively, from estuarine water in a mangrove forest and soil in a terrestrial forest in Thailand. Analysis of the D1/D2 domains of the large-subunit rRNA gene sequences revealed that strain TM3-44T differed from the closest species in terms of pairwise sequence similarity, Dipodascus albidus, by 11.7% nucleotide substitutions, while strain LYSM5T was closest to Galactomyces geotrichum with only 2.9% nucleotide substitutions. The phylogenetic tree further demonstrated that strain TM3-44T was at a distant position from the closest species, D. albidus, and other related species in the Dipodascus clade, while strain LYSM5T clustered with G. geotrichum, it closest relative in the Galactomyces clade. The phenotypic characteristics of the two strains were typical of the genus Geotrichum. On the basis of the above findings, strain TM3-44T was assigned as a novel species of Geotrichum, for which the name Geotrichum siamensis sp. nov. is proposed. The type strain is TM3-44T (BCC 29903T=NBRC 104880T=CBS 10929T). Strain LYSM5T represented another novel species of Geotrichum, which was named Geotrichum phurueaensis sp. nov. The type strain is LYSM5T (BCC 34756T=NBRC 105674T=CBS 11418T). [ABSTRACT FROM AUTHOR] |
