Saccharomyces pastorianus is a yeast used industrially for the production of lager beer, and was named in honour of Louis Pasteur by the German Max Reess in 1870. [1] This yeast's complicated genome appears to be the result of hybridisation between two pure species in the Saccharomyces species complex, a factor that led to difficulty in establishing a proper taxonomy of the species.
Molecular research, based on cladistic analysis of DNA sequences, has shown that Cystobasidium (based on the type species) is a monophyletic (natural) genus. An additional 20 or so yeast species have been added to the genus, most of which were formerly placed in Rhodotorula .
Saccharomyces cerevisiae virus L-A, also called L-A helper virus, is a member of the Totiviridae family of viruses found primarily in Saccharomyces cerevisiae. [3] Its discovery in the 1970s was the main starting point of research on yeast virology. [ 4 ]
Saccharomyces is a genus of fungi that includes many species of yeasts. Saccharomyces is from Greek σάκχαρον (sugar) and μύκης (fungus) and means sugar fungus.Many members of this genus are considered very important in food production where they are known as brewer's yeast, baker's yeast and sourdough starter among others.
Invasive candidiasis is an infection (candidiasis) that can be caused by various species of Candida yeast. Unlike Candida infections of the mouth and throat (oral candidiasis) or vagina (Candidal vulvovaginitis), invasive candidiasis is a serious, progressive, and potentially fatal infection that can affect the blood (), heart, brain, eyes, bones, and other parts of the body.
The capsule functions as the major virulence factor in cryptococcal infection and disease. [ 5 ] Some Cryptococcus species have a huge diversity at the infraspecific level with different molecular types based on their genetic differences, mainly due to their geographical distribution, molecular characteristics, and ecological niches.
Rhodotorula glutinis is the type species of the genus Rhodotorula, a basidiomycetous genus of pink yeasts which contains 370 species. Heterogeneity of the genus has made its classification difficult with five varieties having been recognized; however, as of 2011, all are considered to represent a single taxon. [1]
Kluyveromyces marxianus is not usually an agent of human disease, although infection in humans can occur in immunocompromised individuals. [15] This species has been associated with candidemia [16] and has been recovered from catheters. [17] It has also found in biofilms on other indwelling devices such as pacemakers and prosthetic heart valves ...
