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.
Amylase thrives in the pH range of 6.5 to 7. Amylase is an enzyme that helps turn starch into sugars.
Amylase is an enzyme that digests carbohydrates. Generally when spoke of this way the mouth is this enzymes location, so a pH of 7.4 sounds about right.
Alpha-amylase work in the range of pH 6,7-7.
pH 7.
identify two pH values at which salivary amylase activity stop?
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.
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.
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.
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 amylase from sweet potato is about 6.0
The optimum pH is neutral, 7.

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.
The optimum pH of salivary amylase is 6.8 (slightly acidic).
pH optimum: 7.8 (pH 6.0: about 35% of maximal activity, pH 9.3: 40% of maximal activity)
pH of about 7
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.
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.
It depends of the enzyme. For instance. Amylase in the mouth has a higher pH than say pepsin in the stomach.
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.
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.
