A temperature of 65 degrees C is often used to kill yeast completely in alcoholic drinks.
Beyond 60 degrees most common biological enzymes will denature (bodily enzymes may denature as low as 45 degrees, for example).
You could heat your solution much higher...but you risk destroying other things in the solution that you may want (like flavourings).

How does the temperature of water affect the growth of yeast?
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.
What is the temperature of a yeast environment?
The temperature of a yeast environment will have to be at 100 degrees Fahrenheit. Warmer temperatures will start to kill off the yeast, while colder temperatures will make it go dormant.
What is lager and clarification in brewing beer?
A lager is fermented at relatively cooler temperatures using bottom-fermenting yeast. Compare to an ale, which uses top-fermenting yeast at warmer temperatures. Clarification is the precipitation of the yeast from the finished brew.
True or False the main difference between a Lager and an Ale is the type of yeast used?
True Lager is distinguished from ale by its yeast. Lager yeast ferments at lower temperatures and flocculates on the bottom of the fermenting vessel, while ale yeast ferments at higher temperatures and settles on the tops of fermentation tanks.
Why are high temperatures not suitable for anaerobic fermentation?
Temperatures in excess of 40oC will denature the enzymes (proteins) in the yeast, which makes them inactive.
What happen when you mix yeast with salt?
The yeast die.
Why doesn't yeast rise in hot or cold temperatures?
If the temperature is too low, the yeast will remain dormant. If the temperature becomes too hot, the yeast organisms will be overwhelmed and killed before they can respire.
Do high temperatures kill yeast?
Yes, which is why wine and beer brewers must make sure the wort is not too hot before adding the yeast.
A cookbook says that yeast works most quickly with water at a temperature of 20 c to 30 c?
At low temperatures (0-10 C) yeast will not grow, but not die either. At temperatures 10-37 C yeast will grow and multiply, faster at higher temperatures with an optimal growth at 30 or 37 C (that depends on the species). At higher temperature the cells become stressed, meaning that their content becomes damaged and which can be repaired to some degree. At high temperatures (>50 C) the cells die.
If yeast can live can it die if it was stopped beind fed?
yes and no some parts of yeast can die and some can live
Where is lager from?
Lager is a type of beer that has been fermented using yeast that prefers a cooler temperature than ale yeast. It is made of the same ingredients as beer, namely barley, water, hops, and yeast. The only difference between Lager and Ale is the type of yeast used and the temperatures that it is fermented at. Lagers are a "bottom fermenting" beer that prefers cooler temperatures. Ales are "top fermenting" beers that prefer warmer temperatures.
Does yeast die when cooked?
Yes, Yeast dies at 130 degrees Farhrenheit.
