SDS-PAGE analysis revealed that the GST-HF93 fusion protein had an apparent molecular weight of 38 kD and accumulated up to 50% of bacterial soluble proteins.

表达产物经谷胱甘肽S转移酶亲和层析柱纯化，得到的融合蛋白纯度达90％以上。

Based on the cloning FeSOD gene of the HZNH, the recombinant prokaryotic expression vector, PQESOa/FeSOD, was constructed and digested with restriction endonuclease BamH I and Pst I to check its construction. The PQE30a/FeSOD was then transformed into E.coli Ml5 and induced with IPTG. The high expression in vitro was obtained and analyzed on SDS-PAGE gel. The*results showed that the target proteins held a 37% portion in whole bacterial proteins and consisted of two parts, the soluble proteins and inclusion bodies. The soluble proteins in the aqueous layer, checked by means of activities of FeSOD enzymes and analyzed by means of activities of isozymogram from PAGE, demonstrated the induced expression proteins had the active nature of FeSOD enzymes.

以克隆的特异种质烟草HZNH的FeSOD基因为基础，构建了原核表达载体PQE30a／FeSOD，经限制性内切酶BamH Ⅰ、Pst Ⅰ双酶切鉴定后，再转化入大肠杆菌M15中，通过IPTG诱导，得到高效体外表达，经SDS-聚丙烯酰胺凝胶电泳检测，表达的目的蛋白占总菌体蛋白的37％，可溶性和包涵体两种形式均有存在，上清中的可溶性蛋白经FeSOD酶活测定和同工酶活性谱带分析，表明诱导表达的上清中的目的蛋白为有活性的FeSOD酶。

本文着重研究了氧化亚铁硫杆菌对砷黄铁矿和黄铁矿单矿物的氧化规律及其性能之差异，考察其对砷的适应能力及表面活性剂的影响。

In this paper, contrast flask bacterial tests of high arsenic gold concentrate with arsenopyrite type and pure arsenopyrite mineral showed that the pyrite in the concentrate promoted the efficiency of dearsenication rate of the mineral, it was significantly higher than pure arsenopyrite.

通过毒砂型高砷金精矿和单矿物纯毒砂的氧化对比摇瓶试验，发现由于金精矿中黄铁矿的存在促进了矿物的脱砷效率，脱砷速度明显高于纯毒砂。
