RESUMO

Spencer, J. F. T. (University of California, Davis), H. J. Phaff, and N. R. Gardner. Metschnikowia kamienskii sp. n., a yeast associated with brine shrimp. J. Bacteriol. 88:758–762. 1964.—A description is given of Metschnikowia kamienskii sp. n., four strains of which were isolated from brine shrimp (Artemia salina) collected from a saline lake near Watrous, Saskatchewan, Canada. In addition, we obtained from N. van Uden a fifth strain which was originally isolated by L. J. Wickerham from sporocysts of the trematode Diplostomum flexicaudum parasitizing the hepatopancreas of a lymnaeid snail found in Lake Douglas, Michigan, in which material the yeast was first observed by Kathleen Hussey of Columbia University. All strains were identical and formed long club-shaped asci, containing a single needle-shaped spore, pointed at both ends. M. kamienskii differs in several of its physiological properties and by the size of its asci from the two previously isolated members of the genus, M. krissii and M. zobellii. A key differentiating the three species is given.
