双杆菌

Objectives The study was to investigate the adhesive ability of the intestinal probiotics as living and heat-killed Bifidobacterium to human colon cultured carcinoma cell line HT-29 cells. Methods With microscope the adherence index of the living and heat-killed Bifidobacterium were observed.

双歧杆菌是人体肠道重要的益生菌，对宿主发挥生物屏障、营养、免疫、控制内毒素血症、延缓衰老、抗肿瘤等生理作用，能够防止多种疾病和不良反应的发生，目前已广泛应用于益生菌制剂的研制。

Using plant bivalent expression vector pCAMBIA1300 and pBI121 as basic components, a new binary vector harboring tomato chitinase gene Chi3 and tomato β-1,3-glucanase gene Glu-Ac, was constructed through sequential restriction digests and ligations recombination. The two genes driven by CaMV35s promoter were successfully transferred into watermelon cultivars "ZhongYuYiHao" via Agrobacterium-mediated transformation.

构建了同时含有番茄儿丁质酶基因（Chi3）和β-1，3-葡聚糖酶基因的双价抗真菌基因植物表达载体，以西瓜子叶块为外植体，采用根癌农杆菌介导法，将Chi3和Glu-Ac同时导入西瓜栽培种&中育一号&，共获得46株抗性再生植株。

In addition, because two-pronged role of Lactobacillus, intestinal acid has shown a stool in the intestines has been oxidized into a green body, the large intestine in normal times there is mucus, which plays the role of lubricants, the mucus and stool with only body only; do not have to worry about.

另外，因双叉乳杆菌的作用，肠内已呈酸性，大便在肠内已被氧化，变成绿色排出体外，大肠中平时就有粘液，它起着滑润的作用，该粘液只是与大便一起排出体外而已；不必为此而担心。

The 329 bp terminal inverted repeat sequence can't form the conserved fold-back secondary structure as that of many Streptomyces linear replicons. Lacking of typical Streptomyces tap/tpg locus for te-lomere replication, pPR2.3c encodes a protein with two domains resembling the telomere associated protein of Strepto-myces and helicase of Haemophilus respectively. No typical Streptomyces iteron-rep locus for replication from the cen-trally located origin, two DNA fragments containing almost all pPR2 were cloned and introduced by transformation into S.

其端粒末端反向重复序列的长度为329 bp，不能像多数链霉菌的线型质粒那样能形成保守的&折返&的二级结构。pPR2虽然没有参与链霉菌端粒复制的保守的tap/tpg基因，但是pPR2.3c基因编码了一个双结构域蛋白，分别同链霉菌的端粒复制相关蛋白Tap和嗜血杆菌的解旋酶具有相似性。pPR2缺少典型的链霉菌重复序列-复制基因区段，将几乎覆盖全长pPR2的两段DNA进行克隆后，不能转化变铅青链霉菌。

Spades A germinal main series of products and dietary fiber, Bifidobacterium, soy isoflavones, black beans and plant Insulin Pill series of health food.

主要有黑桃A生发系列产品及膳食纤维、双歧杆菌、大豆异黄酮、黑豆浓缩丸和植物胰岛素等系列保健食品。

There are 123 genes encoding two-component system components in the bacteria, which serve as a stimulus-response coupling machinery allowing the organism sense and respond to the changes in environment.

在已解码的基因体序列中，发现绿脓杆菌具有123个双分子讯息传递系统，藉以侦测环境的变化与刺激、调控适当的基因表现，使细菌可以适应环境、躲避免疫系统及抗生素的攻击。

All kinds of protectants were studied under the freeze-dry condition and four types of protectants, which have good effect, were screened out.

真空冷冻干燥过程中使用的各种保护剂作了详细的研究，在各种保护剂中筛选出4种效果比较好的类型，配合成复合保护剂，在很大程度上提高了双岐杆菌在冻干过程中的活菌存活率。

Objective: To observe the inhibition effect of chitlsan oligosaccharide and bifidobacteria on tumour.

目的：观察壳寡糖协同双歧杆菌对肿瘤抑制作用的影响。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.

集团所属工厂主要生产多用钳、烤具、刀具、剪刀、厨具、花园工具、美容套等五金产品，年生产总值3000万美元，产品价廉物美、选料上乘、质量保证，深受国内外客户的青睐
