32 U/mL enzyme activity can be detected in medium after fermentation. By optimizing the zymotic medium and fermentation conditions, recombination B. subtilis can express as high as 110.02 U/mL of Alkalineβ-mannanase. Cycle of fermentation needs 5 days(4 days is needed in induced expression ), then enzyme activity maintained at the highest level, less than 5 % enzyme activity was lost in next 2 days.

为了继续对碱性β-甘露聚糖酶进行高表达研究，试验采用了芽孢杆菌发酵培养基来进行产酶研究，初步诱导酶活达到29.32 U/mL，通过对发酵条件的优化，该重组枯草芽孢杆菌的产酶水平有了大幅度的提高，最高可达110.02 U/mL。

The results indicated that the white flower was dominant over yellow and the erucic acid content was additively inherited. Both traits fit with a monogenic inheritance model, respectively. There were strong evidences to support the linkage relationship between the flower colour and the erucic acid content in the C-genome of B. napus with a recombination frequency of 4.8% in the DH population.

对亲本、F1、BC1、F2和DH 5个世代的花色及芥酸含量进行分析，结果表明：花色受单基因控制，且白花对黄花为显性；芥酸含量仅表现出一对基因的差异且具有加性效应的遗传模式。

The results demonstrated that recombination was not only physical mixed, but also connected by hydrogen bond between silicic polymer and free or hydrolyze-polymerized aluminum ion and polysilic acid which could form aluminiferous during the process.

结果表明，复合过程不是简单的物理混合，部分铝离子及水解络合铝离子可与共存的聚硅酸通过羟基结合，发生络合反应生成铝硅聚合物。

Ongoing projects involve targeted gene disruption, high-throughput approaches for functional exploitation of Plasmodium and Anopheline genomes and identification of molecular components of the recombination machinery in malaria parasites.

正在进行的项目包括有针对性的基因破坏，高通量的方法开发功能疟原虫和按蚊基因组和分子识别元件的重组机制的疟疾寄生虫。

Ascomycetes also important in study of mitotic recombination via a parasexual cycle.

子囊菌在研究准性生殖中也是重要的。

In addition, it is assumable that the electrons returning to Au will cause the degradation of driving force to capture free electrons from TiO2. As a result, the recombination of electron-hole pairs tends to be increased.

另外，苯乙硫醇将电子回传给金时，造成金吸引二氧化钛电子的趋动力下降，减低捕捉二氧化钛自由电子的能力，增加电子电洞对复合的机率。

Methods S. epidermidis atlE gene expression level at different phases was detected by RT-PCR, and the accumulation of extracellular DNA at different phases was assessed by spectrophotometric measurements of light absorbance by DNA; DNase Ⅰ was used to study the function of extracellular DNA in biofilm formation and primary attachment. The effects of atlE gene deletion on initial adherent capacity, biofilm formation and extracellular DNA release were studied by construction of atlE deletion mutant via homologous recombination.

采用RT-PCR法检测表皮葡萄球菌atZE基因在不同时期的表达水平，用紫外分光光度计检测DNA的方法检测了相应时期的胞外DNA的释放量，并用DNA酶研究表皮葡萄球菌胞外DNA在生物膜形成和起始黏附中的作用；采用ρBT2质粒同源重组敲除的方法构建了表皮葡萄球菌1457的atlE基因突变株，研究atlE基因敲除突变对起始黏附能力、生物膜形成及胞外DNA释放能力的影响。

The reason for above results is that only if Ag is in a state of separating particles, can it be an effective capturer of photo-induced electron and reduce the recombination of photo-generated holes and electrons.
