诱变

Central to everything, an almost obessive research into a natural weightlessness, of ambients that are both emotive and emotional, of materials sensitive and mutated by light.

中央的一切，几乎obessive研究自然失重的ambients既情绪和情感，敏感材料和诱变轻。

So compound mutation isan effective method for genetic breedings.

因此，复合诱变是遗传育种一种有效的方法。

This paper discusses the use of ultraviolet mutagenesis combined chemostat enrichment method to screen high-temperature resistent and high-yield lactic acid bacteria.

本文探讨了利用紫外线诱变结合恒化器富集筛选耐高温高产乳酸菌的方法。

According to the invention, the natural substances in question are selected from: hydroxy-cinnamic acids and the esters and depsides thereof; plant phenols which can be derived from hydroxy-cinnamic acids; polymers of hydroxy-cinnamic alcohols; other natural substances of plant origin which have anti-mutagenic and aromatising properties and are combined with anti-oxydant vitamins or with the precursors and/or derivatives thereof; and other anti-oxidant vitamins which are made to form complexes with eucaryotic cell cultures.

按照本发明，这些天然物质选自羟基肉桂酸及其酯和缩酚酸、可以由羟基肉桂酸衍生得到的植物酚、羟基肉桂醇的聚合物、具有抗诱变性和芳化性质的并且与维生素合用的其他植物源天然物质、以及与真核细胞培养物络合的其他抗氧化性维生素。

The relative activity of a lipase from Candida valida Z6 was studied in hydrolysis of simple esters,fatty acid glycerides and lipidse.

通过与一种不同来源的脂肪酶作比较，研究了粗状假丝酵母诱变株Z6产脂肪酶水解不同底物的相对酶活，包括对低级酯、脂肪酸甘油酯和天然油脂的水解。

Head blight not only causes the severe grain yield loss, but also causes the harvested grain contaminated with several mycotoxins, such as deoxynivalenol and zearalenone. The consumption of food product made from grains contaminated with these toxins is a potential problem for human and farm animals, which is known to cause carcinogenic, genotoxic acute or chronic diseases or to directly target the kidney, liver or immune system, and has caused great concern of food safety.

赤霉菌引起小麦的穗腐，不仅使小麦籽粒产量降低、品质变劣，而且病麦粒中存留有病菌产生的真菌毒素，如脱氧雪腐镰刀菌烯醇(Deoxynivalenol，DON)和玉米赤霉烯酮(Zearalenone，ZEN)，食用污染毒素的病麦及其制成品后会引起人畜中毒，还有致癌、致畸和诱变的作用。

Here, we screened ethyl-methane-sulphonate-mutagensis seedlings on MeIAA medium in the dark, with longer hypocotyls used as a criterion.

我们对拟南芥种子进行EMS诱变，通过观察黑暗下下胚轴的生长情况，筛选MeIAA的抗性突变体。

Perhaps the best understoood form of nuclear damage is that due to irradiation or to mutagenic chemicals such as nitrogen mustards.

人们了解得最清楚的一种核损伤类型，可能是由于放射或诱变的化学物质所导致的核损伤。

A mutagen is very often used to accelerate this process.

为了提高变异的速度，常使用诱变剂来实现。

The same mutagen in the same concentration could increase the ratio of mutagen to PLB with the extended time.

同浓度的同种诱变剂随处理时间的增加材料的变异程度有增大趋势，但不很显著。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
