XC7201 is an interesting protein comprising 176 amino acids. Many sequences in the prokaryote and eukaryote kingdom with high similarity score were detected by BLAST search. It was predicted to a 3-hydroxyanthranilate 3,4-dioxygenase (3HAO), which is an extradiol dioxygenase that catalyzes the final conversion step of tryptophan to quinolinic acid in the kynurenine pathway.

XC7201由176个胺基酸所组成，比对已知物种资料库后发现在原核真核菌中都有类似的序列，其功能被预测为3-hydroxyanthranilate 3，4-dioxygenase (3HAO)。3HAO是一种双氧化酵素，在生物体进行把Tryptophan转变成Quinolinic acid的生合成途径中最后一个反应的催化。

Pristine Li-Al LDHs are synthesized by hydrothermal process in different reaction conditions by varying the aging time for 1 and 24 hours. Both the Li-Al layered double hydroxides (abbreviated as Li-Al LDH1 and Li-Al LDH24 for aging time 1 hour and 24 hours, respectively) were modified by using sulphanilic acid sodium salt hydrate, modified agent to form modified Li-Al LDH1-SAS and Li-Al LDH24-SAS. The morphology of the pristine layered double hydroxides are investigated by using wide angle X-rays diffraction, scanning electron microscopy and particle size analyzer which indicates that the crystallinity and aspect ratio is increased with increasing the aging time from 1 hour to 24 hours. The particle size of Li-Al LDH24 and Li-Al LDH1 are found to be ~1000 nm and ~250 nm, respectively. Both the pristine and modified LDHs are characterized by XRD, FTIR spectra and thermogravimetric analysis.

本研究目的在於改变长晶时间的长短，合成出同径大小的Li-Al LDHs，再经由改质剂sulphanilic acid sodium salt hydrate将Li-Al LDHs无机层材表面有机官能化制备出改质型Li-Al LDHs-SAS，於是进一步藉由扫描式电子显微镜、射径仪和穿透式电子显微镜等仪器分别观察LDHs改质前和改质后其主层结构型态上的变化；从中可以发现Li-Al LDHs随著长晶时间的增加其径有随之增大的趋势，但经有机化改质后其径会由於改质环境的影响明显低许多，针对此现象本实验将未改质和改质后之Li-Al人工无机层材制备成复材进一步探讨其在热性质和难燃特性上的为表现。

Two new complexes, [Mn22(H2bta)2(H2O)]n (1) and [Cu2(H2bta)0.5(H2O)]n (2)(H4bta＝1,2,4,5-benzene- tetracarboxylic acid, L＝imidazo[4,5-f][1,10]phenathroline) were prepared under hydrothermal conditions and their structures determined by single-crystal X-ray diffration.

The range of bacteria that could be effectively detected corresponded to about 10^4 to 5×10^5 cells/mL.
