An extracellular glucose-forming amylase was produced by Lactobacillus brevis isolated from ‘Kagasok tea’. The enzyme was purified 70-fold and had optimal activity at 55 oC and pH 6.5. Its Km value for starch was 0.27 mg ml-1 and its M, was approx. 75,900 Da. The activity of the enzyme was enhanced by Ca2+, Mg2+, Na+ or K+ and inhibited by EDTA, KCN, citric acid and L-cysteine.
