Ambrosiozyma, yeasts that produce true mycelia with transverse septa that communicate by a dolipore type septum, are compared with
Hyphopichia and
Hormoascus. This study includes intracellular oxidases, nitrite and nitrate reductases, guanine plus cytosine content in DNA (GC-content), cytochrome spectra (a+a
3, b, c), coenzyme Q, and serological comparison by immunodiffusion and immunoelectrophoresis, with
A. monospora and
Hormoascus platypodis as references. The results support the division of the genus
Ambrosiozyma into 2 groups based upon GC content, vitamin requirements, and serological homologies. Affinities between
Hormoascus platypodis and
A. philentoma (vitamin requirements, intracellular nitrite and nitrate reductases, β-galactosidase, serological homology, cytochrome spectra, and GC content) leads to the placing of
Hormoascus platypodis in synonymy with
Ambrosiozyma philentoma. Ambrosiozyma ambrosiae is compared with the other
Ambrosiozyma and with the non-fermentative
Pichia, and
Hansenula silvicola. These comparisons show that
A. ambrosiae has more affinity with the other
Ambrosiozyma than with
Pichia or
Hansenula. Hyphopichia burtonii differs from the other species in regard to vitamin requirements, coenzyme Q
8, α
2 band of cytochrome
c and serological homologies.
