Ammonium (methylammonium) transport by Azospirillum spp
In recent years soil bacteria of the genus Azospirillum found increasing biological and ecological interest because of their ability to microaerobically fix N 2 and to live in close association with plant roots, stimulating growth of nitrogenlimited plants [1-5]. The physiology of N 2 fixation, especially its repression by N H + , has been studied extensively [6-9]. The question, however, how N...
متن کاملCell-surface hydrophobicity and cell-surface charge of Azospirillum spp
The cell-surface charge and cell-surface hydrophobicity of 10 strains of Azospirillum spp. were evaluated by the aqueous, two-polymer phase partitioning assay. Azospirillum spp. had moderate cell-surface hydrophobicity and charge, lower than known values for human pathogens. The hydrophobicity and charge values were higher in solid than in liquid media. A general pattern of modifying hydrophobi...
متن کاملAzospirillum spp . metabolize [ 17 , 17 -
; Azospirillum spp. are endophytic bacteria with beneficial effects on cereals — effects partially attributed to gibberellin production by the microorganisms. Azospirillum lipoferum and Azospirillum brasilense inoculated to rice dy mutant reversed dwarfism in seedlings incubated with [17,17-H2]GA20 with formation of [17,17H2]GA1, showing the in vivo capacity to perform the 3 -hydroxylation. Whe...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولRegulation of nitrogenase activity by ammonium chloride in Azospirillum spp.
Ammonium chloride (greater than or equal to 0.05 mM) effectively and reversibly inhibited the nitrogenase activity of Azospirillum brasilense, Azospirillum lipoferum and Azospirillum amazonense. The glutamine synthetase inhibitor L-methionine-DL- sulfoximine abolished this "switch-off" in A. lipoferum and A. brasilense, but not in A. amazonense. Azaserine, an inhibitor of glutamate synthase, in...
