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。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
