Yeast need warm temperatures in order to grow. The perfect temperature for yeast is about 110 degrees F. Yeast will not start to reproduce and rise without warm temperatures to activate it.
Yeast does different things based on temperature.
temperature (30 degrees celcius is the optimum temp for yeast growth), nutrients (e.g. sucrose, fructose, glucose, lactose - (does not affect yeast growth), pH level (5 - 6 is the optimum pH level for growth)
My guess would be that osmotic concentration of the sugar gets so great that the yeast is unable to get enough water for growth.
Directly regulated by sugar and salt. Sugar cuases yeast growth, salt slows. Environmental factors such as moisture, heat and acidity also affect yeast growth.
Temperature of its environment, amount of sugar, type of sugar, and acidity.
yes it does!!!
yes, if your trying to make yeast rise try to leave it out on your counter at room temperature
Temperature, oxygen availability, pH, sugar concentration.
The ideal temperature for yeast growth is 100 to 115 degrees F, but for leavening purposes, the ideal temperature is 80 to 95 degrees F. If the yeast grows too quickly, it will produce large bubble pockets in the bread. Yeast begins to die at 120 degrees F. So it's important to let your yeast dough rise in a spot where the temperature is stable. The cooler the temperature, the slower the yeast grows. It will grow in the refrigerator, but very slowly. I don't know the minimum temperature for it to grow.
Yes. as temperature rises pressure rises and density rises.
yes
