摘要
由地衣芽孢杆菌ＮＫ－２７获得的β－甘露聚糖酶在４０℃、酶液终浓度１ｕ／ｍｌ时，经１２ｈ水解魔芋粉、角豆胶、瓜儿豆胶和田菁胶所生成的酶解产物，经薄层层析检测表明为单糖和低聚糖。在ＰＹＧ和ＧＡＭ液体培养基中，添加不同量的四种植物胶酶解产物对青春双歧杆菌（Ｂｉｆｉｄｏｂａｃｔｅｒｉｕｍａｄｏｌｅ－ｓｃｅｎｔｉｓ）具有明显的促生长作用，菌体增殖数从１０￣７提高到１０￣８个／ｍｌ。
he β-mannanase-producing from Bacillus lichniformis hydrolysis Konjacpowder,Locust bean gum,Guar gum and Sesbania cannabina gum(under the condition:40℃,ultimate concentration of enzyme 1u/ml,hydrolysis time 12 hours)producted mono- di,tri and tetra-saccharides determined by thin-layer chromatogram.Add various weight enzyme hydrolysis-products of tetra-plant gum in the PYG and GAMliquid medium can dramatically increase the growth of Bifidobacterium adolescentis and thereproductive number of bacteria cell increases from 10￣7 to 10￣8 cell/ml.
