Abstract:The yeast strain (Y18) was isolated from a soil sample collected from Fildes Peninsula, Antarctica. The strain is a psychrophilic yeast with optimum and maximum growth temperatures of 10 °C and 18 °C, respectively. Teliospores were formed after 7 d on malt agar, when the germination of teliospores was observed. Both inositol and D-glucuronate were assimilated. Positive results of the DBB (diazonium blue B) color reaction, urease test, and starch formation were observed. The major CoQ is Q 8 . All results indicated that Y18 belongs to the genes of Mrakia. The 18S rDNA sequence analyses showed that Y18 is closely related to Mrakia frigida. DNA-DNA relatedness study, and some biochemistry characteristics indicated that Y18 represents a new species for which Mrakia psychrophila sp. nov. is proposed.

Two new species of ballistospore-forming yeasts, Sporobolomyces griseoflavus and Sporobolomyces sasicola, were isolated from dead leaves of Sasa sp. collected on a mountain in Japan. They form pale colored colonies and bilaterally symmetrical ballistospores, have Q-10 as the major ubiquinone and do not contain xylose in the cells. The taxonomic relationship of these new yeasts to Sporobolomyces singularis are discussed.In the course of investigating ballistospore-forming yeasts living on the surface of various plant materials in Japan, we obtained three strains of hitherto undescribed yeasts from the dead leaves of Sasa sp. collected on mountain in central Japan. These yeasts represent two distinct new species. They are named Sporobolomyces griseoflavus and Sporobolomyces sasicola, and are described in this paper. MATERIALS AND METHODSMicroorganisms. Strains examined were isolated from the dead leaves of Sasa sp. collected on Suga-daira, Nagano Pref., by Dr. G. Okada, in May 1985. These strains were isolated by the ballistospore-fall method of DERx (1) by using YM agar (Difco Labs) plates as described in the previous paper (2).Investigation of taxonomic characteristics. Most of methods used to examine the morphological, physiological, and biochemical characteristics were those described in "The Yeasts, a Taxonomic Study" (3, 4). Assimilation of nitrogen compounds was investigated on solid media with starved inoculum as described in a

“…Some pale coloured new species were capable to assimilate cellobiose latently, but the morphological characters did not agree with those described by van der Walt (17). We decided to classify this strain as a deficient mutant of S. shibatanus (14,15).…”
