A new high-molecular-mass hydroxamic acid containing phenyl as high efficiency flocculant was synthesized by microemulsion polymerication.

摘 要：采用微乳液聚合法合成了一种带有苯环结构的新型氧肟酸类赤泥絮凝剂。

Firstly, Copolymerization of acrylamide and styrene was carried out in a microemulsion system, in which AM aqueous solution was the continue phase and St was the dispersed phase using ST-80 as surfactants respectively, then hydroxamic functions were prepared with hydroxylamine salt at temperatures of from 60℃ to 90℃.

首先以丙烯酰胺水溶液为连续相，以苯乙烯为分散相，ST-80为乳化剂制成微乳液，在15℃~35℃合成丙烯酰胺与苯乙烯的共聚物；然后采用程序控温方式，在60℃~90℃用硫酸羟胺将共聚物羟肟化合成了一种带有苯环结构的嵌段型氧肟酸类聚合物材料。

Cruciferous cancer protection, which may also extend to lung, colon, ovarian, and breast cancer, is attributed to plant chemicals that are metabolized by the body into anticarcinogens called isothiocyanates.

十字花科蔬菜的抗癌作用亦可能对肺癌、肠癌、子宫癌和乳癌等有效，因为这些植物所含的一种植物化合物能经过新陈代谢而产生一种称为异硫氰酸酯的抗癌物质。

On the one hand, lipolytic products can cause milk product＇s bitterness and rancidification during the storage.

在贮存的过程中，一方面脂酶分解乳脂肪造成乳制品变苦和酸败，一方面脂酶增进产品风味，促进产品成熟。

The resulting strain, designated YES2MTM1, was transformed with a yeast genomic library. Transformants lost the plasmid overexpressing MTM1 after 5-FOA treatment. Yeast strains able to grow on nonfermentable carbon source with MTM1 deletion and overexpression of some DNA fragments were picked up and candidate suppressor genes were identified. Overexpression of five genes were identified to be able to rescue the growth defect on nonfermentable carbon source. The study will provide reference for MTM1 gene function and screening for suppressor of genes whose deletion result in irreversible damage.

为了避免MTM1缺失造成的不可逆损伤，在野生型酵母中先转入带有MTM1 基因的质粒，再敲除染色体上的MTM1 基因，随后转入基因组文库，再利用药物5-氟乳清酸(5-FOA)迫使细胞丢失表达MTM1基因的外源质粒，再筛选能在非发酵培养基上生长的转化子，通过这种方法筛选发现，POR2等5个基因的过表达可以挽救MTM1 基因缺失造成的非发酵培养基上的生长缺陷，为深入了解MTM1基因的功能提供了线索，对筛选其他造成不可逆损伤的突变基因的抑制基因提供了一条可行的研究思路。
