The optimum pH of a bacterial amylase depends on the species of bacterium. One review of different species found optima ranging from pH 4 to 11.
To take one example, the α-amylase from Bacillus amyloliquefaciens (BAA) has an optimum pH of 6.
Bacterial amylases are important in a number of industrial processes.

What is the opitmal pH for salivary amylase?
identify two pH values at which salivary amylase activity stop?
Does the optimum pH of salivary amylase differ from plant amylase?
Yes. Some plants are found to have amylase as well, such as those plants with high levels of starch, and they are the same types of amylase.
What are the optimum temperature and the optimum pH of an enzyme?
Every enzyme works at its maximum rate at a specific temprature called as optimum temprature for that enzyme. AND all enzymes work at their maximum rate at narrow range of pH, called as optimum pH. A slight increase or decrease in pH causes the retardation in enzyme activity or blocks it completely.
What is the enzyme's optimum pH?
I believe it's 7.3, the pH of human blood, as most enzymatic reactions occur there. However, there are special enzymes, such as the ones which are in the stomach, which work best at around a pH of 2.
Does PH change the shape of the active site of an enzyme?
Enzymes have different optimum pH levels. Trypsin, which is found in the intestines has an optimum pH of 8-9. Higher or lower than that, its activity decreases until it reaches to a level where the H-bonds holding the protein structure is destroyed. A loss of structure means a loss of function, therefore the enzyme has been denatured. Pepsin on the other hand operates at a more acidic pH, typically 1.5-2. The enzyme, salivary amylase has an optimum pH of 7. In the body, the optimum pH of enzymes vary, the optimum temperature however is close to body temperature, which is 37C or 98.6F. Extreme heat denatures the enzyme, cold on the other hand, only INHIBITS it.
Optimum pH of sweet potato amylase?
optimum pH of amylase from sweet potato is about 6.0
What is the pH optimum of alpha amylase?
The optimum pH is neutral, 7.
What is the opitmal pH for salivary amylase?
identify two pH values at which salivary amylase activity stop?
What are the best conditions in pH for amylase protese and lipase?
Amylase has an optimal pH range of 6.7 - 7.0 and an optimal temperature of around 37 degrees Celsius or 98.6 degrees Fahrenheit. This is what would be expected of an enzyme that needs to be in its most active form in the saliva of the mouth.
What pH does salivary amylase function best?
The optimum pH of salivary amylase is 6.8 (slightly acidic).
What is the optimum pH of Chymotrypsin?
pH optimum: 7.8 (pH 6.0: about 35% of maximal activity, pH 9.3: 40% of maximal activity)
At what pH did you see the highest activity of salivary amylase?
pH of about 7
Does the optimum pH of salivary amylase differ from plant amylase?
Yes. Some plants are found to have amylase as well, such as those plants with high levels of starch, and they are the same types of amylase.
Does amylase activity increase or decrease in the stomach?
The activity of amylase decreases drastcially due to the very low pH this is one of the reasons more amylase is added by the pacreas.
Optimum pH level for enzymes?
It depends of the enzyme. For instance. Amylase in the mouth has a higher pH than say pepsin in the stomach.
Why does amylase work best at pH around 7?
Because that's the average (more or less) pH of the mouth and of the small intestine. If the optimum pH of amylase is not met, the enzyme will denature.
How do the optimum temperature and pH for pepsin activity relate to the location of the enzyme in the body?
In the stomach, the pH could be as low as 2. Pepsin is an enzyme that breaks up protein molecules. It needs to have an optimum pH close to that. In the mouth, amylase occurs. pH in the mouth is often about 7. Optimum pH for amylase needs to be close to that.
