Saccharomyces cerevisiae (/ ˌ s ɛr ə ˈ v ɪ s i. iː /) (brewer's yeast or baker's yeast) is a species of yeast (single-celled fungal microorganisms). The species has been instrumental in winemaking, baking, and brewing since ancient times. It is believed to have been originally isolated from the skin of grapes.
[5] [6] Yeast sizes vary greatly, depending on species and environment, typically measuring 3–4 μm in diameter, although some yeasts can grow to 40 μm in size. [7] Most yeasts reproduce asexually by mitosis , and many do so by the asymmetric division process known as budding .
Antibiotics promote yeast (fungal) infections, including gastrointestinal (GI) Candida overgrowth and penetration of the GI mucosa. [9] While women are more susceptible to genital yeast infections, men can also be infected. Certain factors, such as prolonged antibiotic use, increase the risk for both men and women.
The fission yeast is a single-celled fungus with simple, fully characterized genome and a rapid growth rate. It has long been used in brewing, baking, and molecular genetics. S. pombe is a rod-shaped cell, approximately 3 μm in diameter, that grows entirely by elongation at the ends. After mitosis, division occurs by the formation of a septum ...
The two yeast genera; Pichia and Saccharomyces, have similar growth conditions and tolerances; thus, the culture of Komagataella can be adopted by labs without many modifications. [15] Moreover, unlike S. cerevisiae , Komagataella has the ability to functionally process proteins with large molecular weight, which is useful in a translational ...
Fungemia is the presence of fungi or yeast in the blood. The most common type, also known as candidemia , candedemia , or systemic candidiasis , is caused by Candida species. Candidemia is also among the most common bloodstream infections of any kind. [ 1 ]
The ability to switch between yeast cells and hyphal cells is an important virulence factor. Many proteins play a role in this very complex process. [ 111 ] The formation of hyphae can for example help Candida albicans to escape from macrophages in the human body. [ 112 ]
Candidiasis is a fungal infection due to any species of the genus Candida (a yeast). [4] When it affects the mouth, in some countries it is commonly called thrush. [3] Signs and symptoms include white patches on the tongue or other areas of the mouth and throat. [3]
