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 کاملUltrastructure of Nitrobacter agilis grown under autotrophic and heterotrophic conditions.
Nitrobacter agilis, grown through seven transfers heterotrophically in the absence of nitrite, was examined in the electron microscope. The ultrastructure of such cells closely resembled that of autotrophically grown N. agilis. It was thus futher established that the organisms growing heterotrophically were indeed N. agilis and, therefore, that N. agilis is a facultative autotroph. Acetate inco...
متن کاملNitrogen fixation by white lupin under phosphorus deficiency.
BACKGROUND AND AIMS White lupin is highly adapted to growth in a low-P environment. The objective of the present study was to evaluate whether white lupin grown under P-stress has adaptations in nodulation and N2 fixation that facilitate continued functioning. METHODS Nodulated plants were grown in silica sand supplied with N-free nutrient solution containing 0 to 0.5 mm P. At 21 and 37 d aft...
