Ammonia - oxidizing bacteria which oxidize ammonia to nitrite is a key group of nitrifying bacteria. the population of ammonia - oxidizing bacteria is variable with the different environment
將氨氧化為亞硝酸鹽的氨氧化細菌是硝化菌群的重要組成部分,它的種類隨生境差異而有所不同。Results showed that in the water body of xizi lake, annual average of culturable planktonic ammonifiers and nitrogen fixers were 510 and 236 cfu / ml, respectively ; ammonia oxidizers, nitrite oxidizers, nitrate reducers and denitrifiers were 8. 5, 16, 587 and 16 mpn / ml, respectively ; inorganic phosphate solubilizing bacteria ( 1pb ) and organic phosphorus mineralizing bacteria ( opb ) were 89 cfu / ml and 37 mpn / ml, aerobic and anaerobic cellulose decomposers were 7 and 5 mpn / ml, respectively
水體中可培養異養細菌(氨化細菌)和固氮菌的年平均值分別為510和236cfu ml ,氨氧化細菌、亞硝酸氧化細菌、硝酸鹽還原菌和脫氮菌的數量分別為8 . 5 、 16 、 587和16mpn ml ;無機磷和有機磷分解菌分別為89cfu ml和37mpn ml ;好氧性纖維素分解菌和厭氧性纖維素分解菌只有7和5mpn ml 。Thioredoxins, an ubiquitous small proteins with a redox active disulfide bridge in its conserved motif - cp ( g ) pc -, are universally distributed in eucaryote and procaryote and have a molecular mass of approximately 12kda. by its disulfide / dithiol interchange reaction, this protein can transmit the regulatory signals to seleted targets ( enzymes, transcription factors etc ) and plays an important role in many plant physiological processes that includes photosynthesis, dna synthesis, transcription, protein disulfide reduction, protein repair, filamentous phage assembly, cell apoptosis and seeds germinating and so on
該蛋白質中含有保守的- cp ( g ) pc -氨基酸活性基序,該基序中的兩個半胱氨酸殘基可通過巰基二硫鍵的轉換實現其氧化還原狀態的變化和電子氫的傳遞,對細胞中與氧化還原相關的多種生理過程的調節起重要作用。通過同許多酶類、蛋白類、細胞內活性因子相藕連, trx能對光合作用、 dna復制、基因轉錄、細胞凋亡和生長、噬菌體組裝、蛋白質的還原和修復信號傳導等生理過程產生影響和調節。The results showed about 490bp dna fragments were amplified. because the amplified products is specific to the p - subclass of the proteobacteria, the amplification of the amoa gene may be a powerful molecular tools for detecting and analyzing ammonia - oxidizing communities in environment
由於基於此引物的擴增對proteobacteria -亞科氨氧化細菌具有特異性,所以amoa基因片段的特異擴增為我們檢測和鑒定環境樣品中氨氧化細菌的種群提供了一個有效的工具。The gene of amoa in ammonia - oxidizing encodes the active - site polypeptide of ammonia monooxygenase which catalyzes the oxidation of ammonia to hydroxylamine. we designed a pair of primers special for the amoa gene by comparing the known amoa gene sequences and used pcr to amplify the amoa gene fragments
Amoa基因是編碼氨單加氧酶活性多肽位點基因,我們通過引物篩選合成了對氨氧化細菌amoa基因特異結合的引物序列,利用pcr技術對活性污泥中的amoa基因片段進行特異擴增,得到的dna片段大約為490bp 。Nitrification, performed oxidation of ammonia to nitrate by nitrifying bacteria is a key process in the cycling of nitrogen and an impotent component of modern wastewater treatment
