Ciri dan struktur
Colonies of K. marxianus are cream to brown in colour with the occasional pink pigmentation due to production of the iron chelate pigment, pulcherrimin. When grown on Wickerham's Yeast-Mold (YM) agar, the yeast cells appear globose, ellipsoidal or cylindrical, 2–6 x 3–11 μm in size. In a glucose-yeast extract broth, K. marxianus grows to produce a ring composed of sediment. A thin pellicle may be formed. In a Dalmau plate culture containing cornmeal agar and Polysorbate 80, K. marxianus forms a rudimentary to branched pseudomycelium with few blastospores. K. marxianus is thermotolerant, exhibiting a high growth rate at 40 C.
Habitat dan peran ekologis
Kluyveromyces marxianus has been isolated in dairy products, sisal leaves, and sewage from sugar manufacturing factories. It is also a naturally occurring colonist of plants, including corn.

Reproduksi
Kluyveromyces marxianus in ascomycetous yeast and member of the genus, Kluyveromyces. It is the sexual stage (teleomorph) of Atelosaccharomyces pseudotropicalis also known as Candida kefyr. This species has a homothallic mating system and is often isolated from dairy products. The formation of the ascospores occurs through the conjugation of the haploid cells preceding the formation of the ascus. Alternatively, ascosporogensis can arise directly from diploid cells. Each ascus contains 1–4 ascospores. The ploidy of K. marxianus was originally thought to be a haploid but recent research has shown that many strains used in research and industry are diploid. These conflicting findings suggest that K. marxianus can exist in vegetative form either as a haploid and a diploid.
