[Assimilation of glucuronic and gluconic acids and ketogluconates by Torulopsis species]. / Ob assimiliatsii vidami Torulopsis gliukuronovoi, gliukonovoi kislot i ketogliukonatov.

Yeast strains (75) of the Torulopsis genus belonging to 42 species and varieties were studied. Most of them readily assimilated glucono-delta-lactone, with the exception of species that were imperfect analogues of the species Saccharomyces and Kluyveromyces. Only five of the species were capable of assimilating 5-keto-D-gluconate, and merely two of them, namely, T.ingeniosa and T. fragaria, assimilated D-glucuronic acid. These species have a basidiomycetic affinity in chemotaxonomic features.

[Comparative study of Candida zeylanoides and Candida vinaria]. / Sravnitel'noe izuchenie Candida zeylanoides i Candida vinaria.

Candida zeylanoides (Castellani) Langeron et Guerra 1920 and Candida vinaria Ohara, Nonomura et Yunome ex. M. Th. Smith 1973 were comparatively studied. The species were found to differ in the assimilation of nine carbon sources, the vitamin requirements, the resistance to elevated NaCl concentrations, the ability to utilize hydrocarbons. The ultrafine structure of the cell wall and the type of budding in C. vinaria are as in ascomycetous yeasts while the cell wall structure and the formation of buds in C. zeylanoides are as in basidiomycetous ones.
