The ultrafilteration is applied in the separation and concentration of the zymin, it can be operated in the normal temperatures, overcome the effects heat does to the quality of the fermented products, abstract small molecular admixtures, and guarantees filtrates purity and quality; Filtering process does not change, the energy consumption and the cost compared with the traditional method are lower; The equipment running is simple, and is easy to operate and the control, thus it quickly became concentration separation craft the first choice of concentration separation such as biology medicine manufacture.

现在采用超滤技术进行酶制剂的分离浓缩，则可在常温下操作，克服热对发酵产品品质的影响；除去其中的小分子杂质，保证滤液的纯净度和品质的良好性；过滤过程无相变，能耗和成本较传统方法都低；设备运行简便，易于操作和控制，因而很快成为了生物制药等行业分离浓缩工艺的首选。

Preliminary bioassays indicated that many title compounds exhibited excellent fungicidal, or insecticidal and acaricidal activities. The strobilurin derivatives containing substituted pyrimide ring have lower biological activity than the strobilurin derivatives containing substituted pyrazole ring which exhibited good fungicidal activity against RB (0.92 mg/L), TLB (0.3 mg/L), CDM (12.5 mg/L) and WPM (1.56 mg/L).

初步生物活性测定结果表明，新型Strobilurin类化合物中多个化合物具有较好的杀菌或杀虫杀加热管螨活性，其中吡唑类化合物要明显优于嘧啶类化合物，吡唑类化合物在低浓加热管度下对水稻稻瘟病菌(0.92 mg/L)、番茄晚疫病菌(0.3 mg/L)、黄瓜霜霉病(12.5 mg/L)和小加热管麦白粉病(1.56 mg/L)仍具有很好的杀菌活性。

The SPR, the participant manner and the interferential mechanism of adscititious reagents, and the bioinorganic effect of Me〓 can be successfully explained by the information systems.

该体系能够提供考察中药小分子-BSA相互作用的基本信息，能够对构效关系、外加剂的扰动机制、Me〓的生物无机化学效应等给予比较成功的解释。

Neuroglobin, a recently identified monomer globin in nerve system, is highly affinitive with oxygen similar to myoglobin. After the coding region of rat NGB gene was sub cloned into the prokaryotic expression vector pGEX 4T 2, the recombinant vector was introduced into E. coli BL21 (DE3) cells for efficient expression.

氧是人类及许多生物赖以生存的重要条件，严重缺氧和低氧可危及人体生命。2 0 0 0年 9月，德国Burmester等人首次报道了人和小鼠脑内存在特异的功能上类似于肌红蛋白的携氧蛋白———脑红蛋白(neuroglobin ，NGB) [1 ] 。

Alkylidene cycloketones such as aza-cycloketones are common features of many bioactive compounds. Few methods reported are effective to construct these motifs in a stereospecific and controllable manner.

芳亚烷基-环酮结构尤其是含有氮原子的3-亚烷基-哌啶-4-酮是生物活性小分子中一种较为常见的结构，对其合成方法的研究报道却很少，已知的方法具有很大的局限性。

According to the spetial conformational analysis and physical/chemical property analysis and by the aid of computer it can make molecular design of mimic polypeptide and designs the polypeptide molecule with activity for neutralizing LPS, and adopts the solid phase polypeptide chemical synthesis method to synthesize antibacterial/antiendotoxin mimic peptide with total or partial BPI bio-function.

本发明公开了通过计算机模拟设计、人工合成的66个抗菌／抗内毒素模拟肽，根据对BPIN端三个LOOP区的空间构象分析及物理化学性质分析，在计算机辅助下进行模拟多肽的分子设计，设计出具有中和LPS活性的多肽分子，用固相多肽化学合成方法合成抗菌／抗内毒素模拟肽，本发明的抗菌／抗内毒素模拟肽具有全部或部分BPI的生物功能，可以用于治疗G－细菌感染、人内毒素血症，具有分子量小、可以稳定重复生产的特点。

Been long-term protected by local people, a stable heron community has been formed at Wanheshan either, it includes 10 species of Ardeidae, among them 7 species nested together to form a large "heron woods", it is of high value in scientific research.

因此，该保护区在生物多样性保护中具有重要作用。亦是经过当地群众长期自发保护，在防城区万鹤山亦形成了一个稳定的鹭鸟群落，保护区内现有鹭科鸟类10种，其中7种鹭鸟聚集在万鹤山小范围内营群巢，成为大型复杂的鹭林，具有极高的科学研究价值。

This past holiday season, nativity figurines made from Tecnaro's "liquid wood" raised eyebrows among the bioplastic community.

在刚刚过去的假期里，用Tecnaro公司的&液体木材&制成的耶稣诞生小塑像在生物塑料界引起了轰动。

This study was performed to design a kind of biosynthetic vascular graft suitable for bypass procedures of middle and small arteries.

本课题设计研制出一种适用于中、小动脉旁路术的新型生物一人工复合血管。

A pot experiment was carried out in greenhouse to observe the yield, the absorption amount of cadmium and zinc of rape（ Brassia campestris L.）, and soil pH responses to different amendments applied in red soil, a typical soil of China.

采用盆栽试验，研究了施用改良剂—石灰、有机肥、海泡石对红壤上小油菜生物产量、镉锌吸收量、pH、吸收系数的影响。

I didn't watch TV last night, because it .
