Candida chanthaburiensis sp. nov., Candida kungkrabaensis sp. nov. and Candida suratensis sp. nov., three novel yeast species from decaying plant materials submerged in water of mangrove forests.

In a taxonomic study of yeasts isolated from decaying plant materials submerged in water of mangrove forests in Thailand, three strains isolated from tree bark (EM33(T)), a fallen leaf (EM40(T)) and a detached branch (SM56(T)) were found to represent three novel yeast species. On the basis of morphological, biochemical, physiological and chemotaxonomic characteristics, the sequence analysis of the D1/D2 domain of the large subunit (LSU) rRNA gene, and the phylogenetic analysis, the three strains were assigned as three novel Candida species. They were named as Candida chanthaburiensis sp. nov. (type strain EM33(T) = BCC 23057(T) = NBRC 102176(T) = CBS 10926(T)), Candida kungkrabaensis sp. nov. (type strain EM40(T) = BCC 23060(T) = NBRC 102179(T) = CBS 10927(T)), and Candida suratensis sp. nov. (type strain SM56(T) = BCC 25961(T) = NBRC 103858(T) = CBS 10928(T)).
