Candida andamanensis sp. nov., Candida laemsonensis sp. nov. and Candida ranongensis sp. nov., anamorphic yeast species isolated from estuarine waters in a Thai mangrove forest

Five strains (RV5 T , RV140, R31 T , RS17 and RS28 T ) representing three novel anamorphic ascomycetous yeast species were isolated by membrane filtration from estuarine waters collected from a mangrove forest in Laem Son National Park, Ranong Province, Thailand, on different occasions. On the basis of morphological, biochemical, physiological and chemotaxonomic characteristics, sequence analysis of the D1/D2 domain of the large-subunit rRNA gene and the internal transcribed spacer region and phylogenetic analysis, three strains were found to represent two novel Candida species. Two strains (RV5 T and RV140) represented a single novel species, for which the name Candida laemsonensis sp. nov. is proposed. The type strain is RV5 T (=BCC 35154 T =NBRC 105873 T =CBS 11419 T ). Strain R31 T was assigned to a novel species that was named Candida andamanensis sp. nov. (type strain R31 T =BCC 25965 T =NBRC 103862 T =CBS 10859 T ). On the basis of morphological, biochemical, physiological and chemotaxonomic characteristics, sequence analysis of the D1/D2 domain of the large-subunit rRNA gene and phylogenetic analysis, strains RS17 and RS28 T represented another novel species of Candida , for which the name Candida ranongensis sp. nov. is proposed. The type strain is RS28 T (=BCC 25964 T =NBRC 103861 T =CBS 10861 T ).
