Identification of functional bacteria showed predominant ammonifiers were shewanella, variovorax, chryseobacterium, bacillus or aeromonas ; among 4 selected nitrogen fixers, one ( azorhizobium caulinodans ) belonged to. a - proteobacteria, the other three ( serratia marcescens, klebsiella pneumoniae and citrobacter freundii ) were enterobacteriace, which belongs to - proteobacteria ; 2 nitrate reducers were aeromonas sp. and citrobacter sp.,
對各功能菌群中的優勢菌的鑒定表明，優勢的氨化細菌為希瓦氏菌屬，產堿菌屬，黃桿菌屬，芽孢桿菌屬或氣單胞菌屬；分離到的4個優勢固氮細菌菌株中，一株為基瘤固氮根瘤菌，屬于-變形菌亞門，而另外3株都屬于腸桿菌科，歸于-變形菌亞門。The effect of rhizobium fredii hnol on the speciation of cu, zn and cd was studied in two china soils. first we discussed the fixation of cu, zn and cd by soils and the speciation of immobilized heavy metal when the soils adsorbed the studied bacterium
本文研究吸附大豆根瘤菌（ rhizobiafredii ） hn01后外源重金屬在湖南郴州紅壤和河北鞏義褐土的吸持及形態分佈以及根瘤菌的代謝活動對重金屬污染土壤中重金屬的形態影響。Results of g + c mol % test shown that all slow - growing isolates were belong to the same species. more than 70 % dna - dna homologies were determined among 4 representative strains usda6, and usda110 ( type strains of b. japonicum ). low dna homologies were detected with usda76 ( type strain of b. elkanii )
中l習花生根瘤菌遺傳多樣性和系統發育研究g + cmol %和dna一dna同源性分析結果表明，供試花生根瘤菌代表菌株的tm和g + cmol %均小於種內變異l隔度，表明供試花生根瘤菌均屬j二一個種。452 rhizobium samples were collected from 18 genera and 30 species of legumes according to the investigation in the middle and western areas of gansu province, and 328 rhizobium strains were isolated
摘要通過對甘肅中西部地區豆科植物共生固氮資源多樣性的調查，共獲得豆科植物根瘤樣品452份，涉及18個屬， 30個種，分離得到328株根瘤菌。Results of phenotype test shown that all peanut isolates and reference strains of b. japonicum and b. elkanii were clustered into a group and differed from the other genus of fast - growing rhizobia in low similarity
表型分析結果表明所有供試菌株與慢生參比菌株b . japonicum和b . elkanii聚為一群，而其它種屬的參比菌株聚為另一群，表明花生根瘤菌在屬的水平上應屬于bradyrhizobium屬。It appeared no remarkedly effect of inoculating rhizobiaon on the cd speciations in cinnamon soil. 4. the effect of inoculating rhizobia on the speciations of heavy metal varied with the metal and the soil
接種根瘤菌對土壤重余屬的形態影響隨土壤和重金屬類型不同而不華中農業大學碩十學位論文郭學軍2001同。Added rhizobia increased the amount of negative charge and metallo - ion specific adsorbing sites of solid compositions such as mn oxides and organic matter etc. the influences of adsorbing rhizobia by soil on the speciation of heavy metal varied with the metal and the soil and were closely related to the mechanisms of metal fixation by soils
土壤吸附根瘤菌后負電荷量增加，某些組分如氧化錳和有機質等吸附重金屬的專性吸附位點有所增加。土壤吸附根瘤菌對土壤中重金屬的形態影響隨重金屬種類和土壤類型而不同，與重金屬在土壤中的吸持機制有直接關系，當重金屬以沉澱機制為主被土壤吸持時，其形態分佈受根瘤菌的影響不顯著。分享友人
