I have just carried out an experiment to investigate th affect of 
different pH on the activity of amylse.
I understand that salivary amylase has an optimum pH of pH8 - due to the 
slight alkalinity of the saliva/ mouth.  In my experiment I used BACTERIAL 
AMYLASE - thinking it would have the same optimum as the salivary amylase -
 I found that it worked best at pH 6 !!!! - Is there a reason for this - 
and can you tell me anything about BACTERIAL amylase?

Thankyou
