Kluyveromyces nonfermentans is a Kluyveromyces species occurring as a yeast. It was originally isolated from the deep sea, with various strains being isolated from sediment, a clam, and a crab. It is notable among the Kluyveromyces species as the only member unable to ferment glucose.
Discovery
In 1999, eleven strains of a previously unknown Kluyveromyces species were discovered in deep-sea samples from Suruga Bay and Sagami Bay off the coast of Honshu, Japan. The samples originated from marine sediment, a Calyptogena clam, and an unknown crab species.
Genomic analysis
At the time of discovery, K. nonfermentans was determined to be most closely related to Kluyveromyces aestuarii based on 18S rRNA gene sequences.
