NodD binds to and bends target promoters through anchoring two tandem and individual specific DNA sites. NodD functions as a tetramer, which has a V-shaped main body. Tetrameric NodD is to change its own conformation rather than its oligomeric forms in response to small signal molecules. The specific interaction between each NodD DNA-binding domain and each specific DNA site does not alter itself in spite of naringenin induction, and the induced conformational change is transferred from protein to DNA. Only the DNA conformation incited by induced NodD is competent for RNA polymerase to form the transcriptional open complex. It cannot be excluded that NodD may have protein-to-protein contacts with RNA polymerase, and that the NodD conformational change may also directly contribute to the transcriptional open complex formation. However, the NodD conformational change itself cannot serve as the determinant of the transcriptional molecular switch.

通过研究，我们提出了初步的NodD操纵子激活模型：第一，四聚体是NodD蛋白的功能单位，它通过铆钉两个串联的相对独立的DNA靶位点结合被诱导的启动子；第二，小分子配基的结合是改变NodD四聚体的构象而不是引发不同形式的寡聚体，在我们的模型中，NodD四聚体缩小其V形主体的弯折角，进而缩短其DNA结合功能域的间距；第三，小分子信号的诱导并没有改变NodD的DNA结合域和其DNA靶位点的相互作用，NodD的构象改变由蛋白质经其双铆钉位点传递给DNA；第四，只有诱导状态的NodD激发的DNA构象才能有效地使RNA聚合酶形成转录开放复合物；第五，不排除NodD与RNA聚合酶可能有直接的相互接触位点，不排除NodD构象的改变可能直接有利于RNA聚合酶形成转录开放复合物，但是我们认为NodD构象改变本身不是充当转录激活开关的决定因素。

针对养殖水体中因氨态氮、硫化氢和小分子有机酸富营养化引起的污染问题，分离筛选出硝化细菌、反硝化细菌、光合细菌、硫化细菌和生物絮凝菌等具有不同生理功能的污染物治理菌株，经优化配伍制备出性能优良的复合功能菌，结果表明：硝化细菌对氨态氮的去除率达97.8%，亚硝态氮的去除率达95.7%，反硝化细菌对硝态氮的去除率为96.4%，光合细菌和硫化细菌对硫化氢的去除率为55%，微生物絮凝菌的絮凝效率为83%；复合功能菌对CODCr、NH4+-N，总氮、硫化物的去除率分别可达94.3%，89.6%，88.7%和71.3%。

Zeiss began to make improvements in microscopes, offering simple microscopes and in 1857 introducing the first compound (which employ an objective and an eyepiece) microscope "Stand I". In 1861 Zeiss compound microscopes are declared to be "among the most excellent instruments made in Germany" and he is awarded a Gold medal at the Thuringian Industrial Exhibition. By 1864 the need to house some 200 employees results in another move of the workshop to a third larger site at Johannisplatz 10. In 1866 the 1000th microscope is delivered; the Carl Zeiss shop is recognized throughout European scientific circles for the quality of its microscopes.

蔡司开始对显微镜进行改进，生产简便显微镜，并在1857年推出了第一种复合显微镜&Stand I&型。1861年蔡司复合显微镜被认为是&德国制造的最出色的仪器&，并被授予图林根工业博览会金奖。1864年由于已经拥有200名雇员了，工厂不得不第三次搬迁到Johannisplatz 街10号的更大的地点。1866年生产了第1000台显微镜；欧洲科学界通过高质量的显微镜而认识了卡尔蔡司工厂。
