Autotrophic Growth and Nitrogen Fixation in Derxia gummosa
Initial attempts to grow N2-fixing Derxia gummosa autotrophically on H2, C 0 2 , O2 and N2 in a closed system yielded variable results. Poor growth was found to be due to rapid O2 depletion and the requirement for an agar surface. In a closed system, C2H2 reduction assays could not be carried out due to complete consumption of H2. Hence a flow-through culturing technique was developed to supply...
متن کاملGrowth and nitrogen fixation of tropical Acacias
Nitrogen is mainly lost from most Australian tropical savanna ecosystems via fire and replenished through symbiotic nitrogen fixation. The frequency and severity of bushfires in Australia, which are common and extensive in tropical savannas, are expected to increase under climate change. Thus the nitrogen loss from tropical savannas can be exacerbated. This research investigates how climate cha...
متن کاملGrowth, nitrogen fixation, and spectral attenuation in cultivated trichodesmium species.
Physiological studies of Trichodesmium species have been hindered by difficulties in maintaining actively growing, nitrogen-fixing cultures. Previous cultivation successes have not been widely duplicated. We present here a simple modified seawater medium and handling techniques which have been used to maintain actively growing Trichodesmium thiebautii in laboratory culture for over 1 year. The ...

متن کاملNitrogen Fixation
Plant growth is directly dependent upon an adequate supply of fixed nitrogen. Water and fixed nitrogen are the most common limiting factors for plant growth.There is an abundance of nitrogen in the atmosphere, but it is in the form of the relatively inert gas, N2, and this must be converted chemically or biologically into a more active form before plants can utilize it. Chemical fixation most c...
