Abstract

A thermostable pullulanase (α-dextrin 6-glucanohydrolase [EC 3.2.1.41]) from a newly isolated Bacillus stearothermophilus strain (TRS128) was purified and characterized. The enzyme hydrolyzed (1→6)-α-d-glucosidic linkages of pullulan to produce maltotriose, and the optimum temperature was 65°C. About 90% of the enzyme activity was retained after treatment at 65°C for 60 min. By using pTB522 as a vector plasmid, the pullulanase gene was cloned and expressed in Bacillus subtilis.
