Babjeviella inositovora was previously classified in the genus Pichia, but gene sequence analysis shows that it is an isolated species unrelated to Pichia, hence its transfer to the new genus Babjeviella.  From multigene analysis, the species appears basal to the large clade that includes the genera Scheffersomyces, Lodderomyces, Metschnikowia, and others.  B. inositovora grows on a wide range of carbon sources and is one of the few ascomycetous yeasts that can utilize myo-inositol as a sole source of carbon.  Strains of the species are known to harbor double-stranded DNA plasmids that confer killer activity against Saccharomyces cerevisiae, Cephaloascus albidus and Citeromyces matritensis.  B. inositovora does not appear common in nature, but has been isolated in the northwestern U.S. and in Russia.
