The yeast Trichosporon porosum suppresses growth of ascomycetes and basidiomycetes belonging to 52 genera. It is due to secretion of a thermostable fungicidal agent. The suppression was maximal at pH 3.5–4.0. Fungicidal preparation obtained from the culture broth was shown to be a mixture of cellobiosides of dihydrodecane acid with different degree of(More)
A novel species of the genus Cryptococcus, isolated from dead needles of Pinus sylvestris, was identified using mycocinotyping and rDNA sequence data. Phylogenetic analysis showed that the novel species was located in the Kwoniella clade of the Tremellales and was closely related to Cryptococcus dejecticola. The type strain of the novel species,(More)
The amount of yeasts in spruce needle litter determined by plating onto needle infusion agar with penicillin can reach about 3 million cells/g, making up over a quarter of the whole micromycete population. During a 3-year survey, over 20 species belonging to nine genera were revealed, among which representatives of the genera Cryptococcus, Fellomyces,(More)
The Kluyveromyces species reassigned to the genera Lachancea and Vanderwaltozyma are insensitive to five mycocins secreted by Pichia membranifaciens. The remaining Kluyveromyces species including species transferred to the genera Kazachstania, Nakaseomyces, and Tetrapisispora are sensitive to them. Only the neotype strain is insensitive to mycocins among(More)
A Rhodotorula colostri strain has been isolated that shows fungicidal activity against related species of the genera Rhodosporidium, Sporidiobolus, and their anamorphs phylogenetically belonging to the order Sporidiobolales (Microbotryomycetes, Pucciniomycotina). The agent secreted has a molecular weight of about 4–5 kDa, is active at pH values ranging from(More)
