1. ecological effects of long - term organophasphate pesticides contamination on soil microflora the long - term effects of organophosphate pesticides contamination on soil microflora were investigated in the present study. little difference in total counts of bacteria, actinomycetes and fungi was observed between the contaminated and the non - contaminated soil. compared with the control there were a slight decrease in total counts of free - living nitrogen - fixer and denitrifying bacteria and a significant increase in those of ammonifying and ammonia - oxidizing and nitrifying _ bacteria in the methylparathion contaminated soil
一、甲基對硫磷長期污染對土壤微生物的生態學效應研究了有機磷農藥甲基對硫磷長期污染對土壤微生物的影響,實驗表明:土壤細菌、放線菌、真菌總的數量影響不大;自生固氮菌和反硝化細菌數量減少;氨化細菌、亞硝化細菌、硝化細菌的數量在污染土壤中卻有所增加;與對照土壤相比,污染土壤呼吸作用下降了29 . 93 ;氨化作用和硝化作用強度得到增強。The autotrophic nitrifying bacteria play a critical role in nitrogen cycle in nature
硝化細菌是一大類在自然界氮循環中起關鍵作用微生物菌群。The number of mold, bacteria, culturable microorganisms, aerobic nitrogen - fixing bacteria, anaerobic nitrogen - fixing bacteria, aerobic cellulose decomposition microbes, anaerobic cellulose decomposition microbes were the most in 16 - year - old organic tea garden, and the biomass carbon and nitrification of edaphon were also the strongest
黴菌、細菌、可培養微生物總量、好氣性自生固氮菌、嫌氣性自生固氮菌、好氣性纖維分解菌、嫌氣性纖維分解菌均以16年生茶園最多,土壤微生物生物量碳和硝化作用也以16年生茶園最強。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。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。The two methods correlation of ammonia - oxidizers and nitrite - oxidizers are 0. 9593 and 0. 9823, respectively. compared with the conventional mpn method, int dehydrogenase method is more rapid, simpler, and easily operated. the detection periods were shorten from 4 weeks of mpn to 2 days. the int dehydrogenase is a pragmatic method for rapid detection of nitrifying bacteria
採用硝化細菌的偶氮鹽( int )還原計數檢測法對活性污泥的硝化細菌進行檢測,所得的結果與傳統的mpn ? griess法檢測值有著很好的相關性, int法檢測周期為2天,具有快速、簡便、操作容易等優點,是一種有推廣價值的硝化細菌快速計數檢測方法。It was showed that temperature and quality of inlet water would affect the activity of denitrification
