    Abstract: Maltooligosyl trehalose synthase (MTSase, EC 5.4.99.15) catalyzes the synthesis of maltooligosyl trehalose by converting the of α (1 → 4) glucosidic linkages on the reducing ends of maltooligosaccharides to α (1 →1) glucosidic linkages. Maltooligosyl trehalose trehalohydrolase (MTHase, EC 3.2.1.141) catalyzes the release of trehalose by cleaving the α-1.4-glucosidic linkage next to the α-1.1-linked terminal disaccharide of maltooligosyl trehalose. Trehalose was synthesized from starch by the cooperative action of these two enzymes. Trehalose is of great interest in many industrial fields. Until now, many studies have been performed to develop effective methods of trehalose production. This research focused on screening strains bacteria were able to produce of trehalose from starch which is novel and economic method for trehalose production. We selected two strains that had MTSase and MTSase strong activity from ten strains that were isolated in Vietnam. Maltooligosyl trehalose synthase (MTSase, EC 5.4.99.15) xúc tác cho phản ứng phân hủy maltooligosaccharide thành maltooligosyl trehalose bằng chuyển đổi glycosyl hóa nội phân tử sau đó maltooligosyl trehalose trehalohydrolase (MTHase, EC 3.2.1.141) thủy phân đặc hiệu maltooligosyl trehalose thành trehalose. Phương pháp sản xuất trehalose từ tinh bột bằng cách sử dụng MTSase và MTHase có tiềm năng ứng dụng trên quy mô lớn với một chi phí khả thi để có thể thương mại hóa sử dụng cho ngành công nghiệp thực phẩm. Trong nghiên cứu này chúng tôi sàng lọc khả năng sản xuất trehalose của 10 chủng vi khuẩn từ đó chọn ra hai chủng có hoạt tính MTSase và MTHase xúc tác cho phản ứng tạo trehalose từ tinh bột tan.
