Abstract A new yeast species (KKU-FW10) belonging to
the Candida genus was isolated from Jasminum adenophyllum
in the Plant Genetic Conservation Project under
The Royal Initiative of Her Royal Highness Princess Maha
Chakri Sirindhorn area, Chulabhorn Dam, Konsan district
within Chaiyaphum province in Thailand. The strain was
identified via analysis of nucleotide sequences from the D1/
D2 domain of 26S ribosomal DNA and based on its morphological,
physiological and biochemical characteristics.
The sequence obtained fromyeast isolateKKU-FW10was 97
percent identical to that of Candida chanthaburiensis (Gen-
Bank accession number AB500861.1), with 506/517 (nucleotides
identity/total nucleotides) matching nucleotides, nine
substitutions and two gaps being detected. This species
belonged to the Candida clade. Regarding morphological
characteristics, isolate KKU-FW10 presents cream-colored
butyrous colonies, vegetative reproduction through budding
and, round cells without filaments or ascospores. The major
ubiquinone detected was Q-9. The above results suggest that
isolate KKU-FW10 is a new member of the genus Candida,
and the name Candida konsanensis is proposed for this yeast.
The type strain of the new species is KKU-FW10T (= BCC
52588T, = NBRC 109082T, = CBS 12666T). In addition,
this KKU-FW10 could potentially produce 58.24 Units/ml of
carboxymethyl cellulase when it was cultured in YP broth
containing 1.0 % carboxymethyl cellulose for 24 h.
