CANDIDA STELLIMALICOLA, A NEW SPECIES OF ANAMORPHIC YEAST ISOLATED FROM STAR APPLE IN THAILAND

Abstract

A new anamorphic yeast species, Candida stellimalicola Suzuki, Nakase et Komagata, is proposed for a strain isolated from Ma-Fueng (star apple) in Thailand. C. stellimalicola resembles Candida diversa, Candida silvae and Candida karawaiewii in traditionally employed taxonomic criteria, but is clearly differentiated from these three taxa by DNA-DNA hybridization, proton magnetic resonance (PMR) spectral patterns of cell wall mannans and serological characteristics of cell surface antigens. Practically, C. stellimalicola is distinguished from C. diversa by its ability to assimilate D-arabinose and DL-lactic acid, its inability to assimilate ribitol, and the lack of alcoholic fermentation, from C. silvae by a different vitamin requirement and its inability to assimilate ribitol, and from C. karawaiewii by its ability to assimilate L-lysine.
