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 。Because there are a great quantity ' s heterotrophic bacteria in the breeding pool, which will have the repulsion action to the insufficient quantity ' s nitrifier and prevent the nitrification, the situation will bring the accumulating of nitrite which is the middle substance of nitrification in water, the long term accumulated nitrite can debase fish and shrimp ' s disease - resistant and decrease the growth and even die
由於養殖池中存在大量的異養菌,受到異養性細菌排斥,本身無足夠數量的硝化菌,硝化作用往往受阻,結果就會引起硝化作用的中間產物亞硝酸鹽在水體內的累積、亞硝酸鹽長期蓄積會使魚蝦等抗病力降低、生長受阻、嚴重者中毒死亡。The diaphragm had the ability to detect the positive serum when it was diluted to 2 ' 11 and so it has good sensitivity ; stored at 4 for at least 7 months, the sensitivity and specificity of the diaphragm did not change, so it has good stability ; when 10 positive serum was detected 3 times, the result is reproducible, so the diaphragm has good reproducible. serums from experimental inoculated piglets was detected. the results showed that when the titer is l : 16, the pigs were infected with streptococcus suis ; and when 1 : 64, the pigs could survive after challege with streptococcus suis. all the results have shown that dot - ppa - elisa was a convenient, rapid, sensitive specific useful method for the detection of antibody
該法以硝酸纖維素膜為固相載體,包被膜載抗原製成的診斷膜片具有良好的特異性:不與仔豬副傷寒、豬巴氏桿菌病、豬大腸桿菌病、豬衣原體病、豬瘟、豬細小病毒病、豬偽狂犬病、豬布氏桿菌、豬丹毒陽性血清反應;膜片具有良好的靈敏性,陽性血清作2 ~ ( - 11 )稀釋亦能檢出;膜片具有良好的穩定性,在4至少能保存7個月,其靈敏性不變。Microbial mineralization is outlined, the effects of thiobacillus, sulfate - reducing bacteria, iron - reducing bacteria, nitrifying bacteria, denitrifying bacteria, and various bacteria that play the roles during the bio - mineralization of uranium and that correlated with the cycle of geological elements were also introduced in this article
摘要概述了微生物成礦作用,並介紹了硫桿菌、硫酸益還原菌、鐵細菌、硝化細菌、反硝化細菌等各種細菌在與鈾的生物成礦過程相關的地質元素循環中所起到的作用。1. in the mpn - griess method of enumeration of nitrite - oxidizing bacteria, the nitrite concentration deeply effect the enumeration results and detection time. the o. lmmol / l nitrite concentration in the culture is the best choice for mpn - griess method and the shortest detection time is 4 week
硝酸細菌mpn ? griess計數法所用培養基的亞硝酸鹽濃度對計數的周期和結果均有影響,採用0 . 1mmol l亞硝酸鹽的培養基,進行4周的計數培養,是最優的硝酸細菌mpn ? griess計數法。Benjamin ' s group confirmed the antimicrobial effect right away by exposing bacteria responsible for stomach infections to stomach acid both alone and mixed with nitrite
班傑明的研究團隊隨即證實,胃酸本身以及胃酸搭配亞硝酸鹽,對感染胃部的細菌具有抗菌的效果。Benjamin has also observed that cavity - causing bacteria self - destruct in a high - nitrite environment, suggesting an experiment to see if a high - nitrate diet prevents cavities
此外,班傑明還觀察到,造成蛀牙的細菌在高亞硝酸鹽的環境下會自我摧毀,意味著高硝酸鹽飲食或許能做為預防齲齒的新實驗方向。Of these, we can identify anoxygenic phototrophs, sulphate reducers and methanogens
從這些裏面,我們可以辨認出無氧光合自營菌,硫酸鹽還原菌,以及硝化細菌Next, lundberg and his coworkers placed saliva from people who had ingested nitrate tablets onto the inside surface of the stomachs of rats
但是,如果在胃酸中添加高濃度的亞硝酸鹽,一個小時內就可殺死這些細菌。分享友人
