No.
Ras2 might be considered a growth stimulating signal for a yeast cell. It stimulated PKA and MAPK activity in the cell.
It is a species of yeast known to cause yeast infections.
Yeast fermentation is a digestive process that it used to perform growth and reproduction. Fermentation is a form of metabolism by yeast.
Yeast require an assimilable nitrogen source for growth and urea is one of the chemicals yeast can use for this purpose. It contains more nitrogen than Di Ammonium Phosphate (used extensively by winemakers) but is less popular due to its links with the production of urethane during fermentation. A lack of assimilable nitrogen will inhibit yeast growth. Excess nitrogen will not compensate for a lack of other nutrients. As a guide 300mg/L of Yeast Assimilable Nitrogen Content (YANC) is recommended for successful fermentation, but it does depend on the yeast strain.
What chemical might cause the yeast population to enter the death phase?
No, yeast bread does not cause cancer. However, some individuals have a rare disease that causes them to be unable to digest the wheat that yeast breads are made from.
Ringworm, athlete's foot, jock itch, and yeast infections.
What is in yeast to cause it to rise
No. Yeast infections in people are caused by a completely different organizm from the yeast used in food.
Yeast is what makes bread rise. It is not a disease.
Stress may cause yeast infections.
Directly regulated by sugar and salt. Sugar cuases yeast growth, salt slows. Environmental factors such as moisture, heat and acidity also affect yeast growth.
Yes.
My guess would be that osmotic concentration of the sugar gets so great that the yeast is unable to get enough water for growth.
Not that I know of. Yeast is a kind of food that makes bread rise! Emma
