Why does alcohol and CO2 production in yeast slow and stop?
The yeast feed on sugar/carbohydrates and their byproducts are Co2 and alcohol. Co2 is in its gaseous state and therefore bubbles out of the solution. Ethanol alcohol stays in the solution. Ethanol alcohol and Co2 are toxic to yeast just like humanities byproducts are toxic to us. So, when beginning a fermentation process the yeast begin feeding on the sugar or carbohydrates and because there is a large supply of food, the yeast population increases. The production of Co2 increases with increasing yeast population. The population of yeast reach a maximum and then their growth begins to be halted by a lack of nutrients and the amount of toxins (alcohol) in there world. The production slows and then stops when there is no more food for the yeast to eat on and/or the amount of alcohol has reached a level at which yeast cannot continue to live in.
Is yeast growth logistic?
Do you mean logarythmic? if so, then yes! Like any bacteria that replicates via binary fission, there is an exponential phase of growth where the yeast are splitting into two at their maximum rate. This will plateau out as resources deplete and toxic byproducts build up - stationary phase. The growth rate would then stop and the yeast will start to die - death phase.
What is the gram stain of yeast?
While they are both dark purple in appearance one of the major differences are microscopic size. Yeast is the larger. Gram positive coccus can create skin infections and toxic shock syndrome. The yeast cells are rapid mutation in comparison.
Is toxic shock syndrome the same as sepsis?
toxic shock syndrome is in your vagina, it happens when new bacteria or yeast are introduced and then rapidly reproduce within the vagina. The vagina can't fight the bacteria (using acidity). sepsis is when your intestines rupture and leak into your body. obviously TSK is cooler.
Does salt kill yeast?
I'm pretty sure it's both, because while yeast and flour mixed with water smells alcoholic (which is a sign of fermentation), when it's mixed with yeast and water it smells like milk. Also, it barely grows, less than just yeast and water. Correct me if I'm wrong!
Fleischmann's yeast. What strain of yeast is it?
Fleischmann's yeast is the trade name for baker's yeast. Baker's yeast is generally Saccharomyces cerevisiae.
Can you get sick from drinking alcohol made of yeast and sugar?
You can get sick from drinking any alcohol, regardless of its origin. Alcohol is toxic (poison) to humans, that's why it gets us drunk and why drunkenness is called 'intoxication'.

Does alcohal have yeast in it?
No, alcohol does not have yeast in it; it is produced by yeast from sugar.
Is yeast in bread different then yeast in yeast donuts?
No,both are similar type.They are called Backer's yeast.
