Bioinformatics analysis showed that the gene sequence was highly consistent with previously reported F3,5H genes, such as GenBank Accession D14588, Z22545, and DQ352142. The encoded amino acid sequence was highly homology with that of GenBank Accession BAA03438.1, BAC10997.1 (Nierembergia sp. NB17) and AV85470.1 at 99%, 88% and 87%, respectively.

生物信息学分析表明克隆的F3，5H基因与GenBank登记号D14588、Z22545和DQ352142等的F3，5H基因序列高度一致；其编码的氨基酸序列与GenBank登记号BAA03438.1、BAC10997.1和AAV85470.1的高度同源，同源率分别为99%、88%和87%。

The characters and performance of the biofilm were studied. When the concentration of nitrite is 206.82 mg/L, the velocity of nitrification is 260 mg/L·d. The best performed bacteria, N-20, were identified as Nitrobacter sp.

实验得到了稳定的自养硝化生物膜；当NO-2浓度为206.82mg/L时，生物膜的稳定硝化速率可达260mg/L·d；经鉴定，硝化速率最高的N20菌株属硝化杆菌属(Nitrobactersp。)。

It has been indicated that Yw18 could utilize methylparathion and ρ-nitrophenol,a main metabolite product for the insecticide,as sole source of carbon and it was identified as Ochrobacterum sp,and capable of degrading 50 mg·L-1 of methylparathion,ρ-nitrophenol,rapidly in 0.5 h and 8 h respectively,after analyzing metabolite products with ga...

用气相色谱法和分光光度法对Yw18的降解性能进行了研究，结果表明，在0.5 h内它对50 mg.L-1甲基对硫磷的降解率达90%以上，在8 h内能将50 mg.L-1对硝基苯酚完全降解。对该菌进行了系统发育研究，并用PCR法克隆其甲基对硫磷降解酶基因mpd。

From polluted water of Huayang pesticide plant,isolated a L-W strain which can grow with methylparathion,ρ-nitrophenol which produced during degradation as the sole source of carbon,and turn them to carbon dioxide and water,it was identified as Arthrobacter sp.

从生产甲基对硫磷的华阳农药厂污水暴气池中，分离到1株能以甲基对硫磷及其降解中间产物对硝基苯酚为惟一碳源生长，且能够将其彻底降解为CO2和H2O的细菌L-W，经鉴定，为节杆菌属。
