Abstract
Bacillus acidicola TSAS1 produced a novel acid-stable, thermostable, Ca2+-independent and high maltose-forming α-amylase with optimum activity at pH 4.0 and 60°C, and T1/2 of 27 min at 90°C. The enzyme saccharified raw as well as soluble starches, and ameliorated bread quality when the dough was supplemented with the enzyme.
