Two forms of yeast cells can survive and grow: haploid and diploid. The haploid cells undergo a simple lifecycle of mitosis and growth, and under conditions of high stress will, in general, die. This is the asexual form of the fungus. The diploid cells (the preferential 'form' of yeast) similarly undergo a simple lifecycle of mitosis and growth.
A thermophile is a type of extremophile that thrives at relatively high temperatures, between 41 and 122 °C (106 and 252 °F). [ 1 ] [ 2 ] Many thermophiles are archaea , though some of them are bacteria and fungi .
The minimum weight of water required may be calculated: yeast weight x 4 = water weight. [4] Yeast viability can be tested by mixing yeast in warm water and sugar, and following a short rest period during which the cells first accommodate to the environment and then begin to grow, a layer of foam is developed by the action of the yeast, a sign ...
The most extreme hyperthermophiles live on the superheated walls of deep-sea hydrothermal vents, requiring temperatures of at least 90 °C for survival. An extraordinary heat-tolerant hyperthermophile is Geogemma barossii (Strain 121) , [ 5 ] which has been able to double its population during 24 hours in an autoclave at 121 °C (hence its name).

Baker's yeast is also sold as a fresh yeast compressed into a square "cake". This form perishes quickly, so must be used soon after production. A weak solution of water and sugar can be used to determine whether yeast is expired. [78] In the solution, active yeast will foam and bubble as it ferments the sugar into ethanol and carbon dioxide.
A 2022 Outside article on heat stroke cites the highest known body temperature that a human was able to survive: “The highest body temperature measured was only 17 degrees above normal. Willie ...
Candida albicans growing as yeast cells and filamentous (hypha) cells. A dimorphic fungus is a fungus that can exist in the form of both mold [1] and yeast.As this is usually brought about by a change in temperature, this fungus type is also described as a thermally dimorphic fungus. [2]
