摘要
由地衣芽孢杆菌（ＢａｃｉｌｌｕｓＬｉｃｈｅｎｉｆｏｒｍｉｓ）ＮＫ－２７菌株产生的胞外β－甘露聚糖酶在４０℃，ｐＨ值６．５～７．０，酶液终浓度１０ｕ／ｇ的条件下，酶解１％魔芋粉和瓜儿豆胶胶液１ｈ后，所获得的酶解产物经薄板层析（展层剂：正丁醇：吡啶：水＝６：４：３，显色剂：苯胺－二苯胺－磷酸）检测表明为单糖和低聚糖。
onjak powder and guar gum have been hydrolysed by the exocellular β-mannanase producting from Bacillus licheniformis NK-27. Under the optimum conditions (40℃ , PH= 6. 5～ 7. 0,1h . 10u/g ultimate enzyme concentration, 1% gum solution)the hydrolysate are mono-saccharide and Oligosaccharides determined by thin-layer chromotography (unfolding agent: n-Butanol: pyridine: Water= 6 : 4 :3; developing agent: phenylamine-Diphenylamine-phosphoric acid).
