In the second section, we describe two novel species that were isolated from the Chigu and Szutsao saltern. On the basis of phenotypic, phylogenetic and genetic analyses, these two strains were considered to represent a novel species of the genus Virgibacillus and Marinobacter, and were named Virgibacillus chiguensis and Marinobacter szutsaonensis according to Chigu and Szutsao saltern.

本研究亦从盐田分离出两株极端耐盐菌，经由型态、生理、生化及分子演化等多重分析比对，确认这两株菌株为新菌种，分别依其分离之盐田命名为七股菌与四草菌，并寄存於菌种保存研究中心。

Separations in semipermeable membrane systems is based on forcing some of the molecules in the system through the membrane while retaining others on the feed side.

半渗透膜的分离体系是基于迫使某些分子通过半透膜而使其它的分子保留在进料一侧。

Additional, in industrial respect, ion exchange fiber can become activator carrier as activator, use at catalysis certain and organic reaction; Can use as dehydrating agent and grease depart material; Use as water sorbent, take off with what divide at the water in storehouse except; Use as material of sex hygiene suction blood, can make radioactivity is absorbed and defend material; Use ion exchange fiber the adsorption to the bacterium and antiseptic ability, make underwear of deodorant insole, health care wait.

另外，在工业方面，离子交换纤维可作为催化剂成催化剂载体，用于催化某些有机反应；可用作脱水剂和油水分离材料；用作水吸附(物质表面吸住周围介质中的分子或离子现象)剂，用于仓库中水分的脱除；用作吸血性卫生材料，可制成放射性吸收和防护材料；利用离子交换纤维对细菌的吸附(物质表面吸住周围介质中的分子或离子现象)和杀菌能力，制成防臭鞋垫、保健内衣等。

They were expressed specifically in pollen, tapetum and ripped anther, showing a high level of S haplotype specific sequence polymorphism, similar to that of the S-RNases.

通过分子生物学方法和杂交授粉试验证明所分离的F-box基因是花粉自交不亲和基因，但目前尚未分离出该类基因相应的表达蛋白。

In this dissertation, firstly, the conditions of isolation and purification of specific toxin fractions produced by Exserohilum turcicum has been studied, and a high-efficient method has been established;secondly, the toxins were analysed by UV-Vis spectrophotometry;then the effect of specific toxin on death rate of corn leaves protoplast was studied by FDA as a tinct reagent;finally, using ANS as a probe and SDS-PAGE to study the membrane protein of the corn leaves with Htl gene. In a word, the aim of the research is to search some existent evidences of the toxin binding site on protoplasmic membrane, and provide proofs for nosogenesis of specific toxin in terms of cytology and the molecular biology.

本研究对玉米大斑病菌1号小种毒素的特异性组分进行分离，建立了高效的特异性毒素分离纯化方法，并对其进行了紫外波谱分析；用荧光素双醋酸酯染色法，测定了毒素特异性组分对原生质体死亡率的影响；进而用1-苯胺基-8-萘磺酸荧光探针标记法和SDS-PAGE电泳法对特异性毒素组分与Htl基因玉米细胞互作过程中的质膜蛋白进行了研究，旨在证明Htl基因玉米细胞质膜上存在特异性毒素组分结合蛋白，为从细胞和分子生物学角度阐明毒素的致病机理提供证据。

From an extensive molecular epidemiological surveillance around the H5N1 infected regions in the past several years, H5N1 viruses were isolated from the wild birds, eg.
