The respiratory system and diazotrophic activity of Acetobacter diazotrophicus PAL5.
The characteristics of the respiratory system of Acetobacter diazotrophicus PAL5 were investigated. Increasing aeration (from 0.5 to 4.0 liters of air min(-1) liter of medium(-1)) had a strong positive effect on growth and on the diazotrophic activity of cultures. Cells obtained from well-aerated and diazotrophically active cultures possessed a highly active, membrane-bound electron transport s...
متن کاملElectrochemical Dinitrogen Fixation
Materials that catalyze efficient electrochemical N2 fixation would open up the possibility of using an N2/NH3 cycle to store and utilize energy from diffuse renewable sources. In such a cycle, N2 and H2O would be electrolytically transformed to NH3 and O2 in an electrolyzer powered by a renewable electricity source. With existing technologies, NH3 can be utilized in solid oxide fuel cells or c...
متن کاملLimited Genetic Diversity in the Endophytic Sugarcane Bacterium Acetobacter diazotrophicus.
Acetobacter diazotrophicus isolates that originated from different sugarcane cultivars growing in diverse geographic regions of Mexico and Brazil were shown to have limited genetic diversity. Measurements of polymorphism in the electrophoretic mobilities of metabolic enzymes revealed that the mean genetic diversity per enzyme locus (among the four electrophoretic types distinguished) was 0.064....
متن کاملDinitrogen Fixation in Illinois Bundleflower
Although Illinois bundleflower is known to contribute N in forage systems (Dovel et al., 1990; Posler et al., Symbiotic N2 fixation capacity may affect productivity of the peren1993; Springer et al., 2001), there is a paucity of informanial legume Illinois bundleflower [Desmanthus illinoensis (Michx.) tion on its N2 fixation capability. Nodulation has been MacMill. ex B.L. Rob. & Fernald]. Our ...
متن کاملBiological Dinitrogen Fixation in Chaparral1
Microbiologist, Pacific Southwest Forest and Range Experiment Station, Forest Service, U.S. Department of Agriculture, Riverside, Calif. Abstract: Presently available data indicate that biological dinitrogen fixation is responsible for the greatest proportion of nitrogen entering chaparral ecosystems. Dinitrogen fixation by the Rhizobium-legume symbioses is relatively unimportant in chaparral w...
