Assimilation of carbon dioxide by hydrogen bacteria.
Autotrophic organisms can use carbon dioxide as their sole source of carbon. Within this group, the chemosynthetic bacteria secure energy for carbon dioxide assimilation by the oxidation of simple inorganic substances, although the photosynthetic organisms obtain this energy from light. The phylogenetic relationships of the chemosynthetic bacteria to the photosynthetic and to the heterotrophic ...
متن کاملCarbon Assimilation Characteristics of the Aquatic CAM Plant, Isoetes howellii.
The relationship between malic acid production and carbon assimilation was examined in the submerged aquatic Crassulacean acid metabolism (CAM) plant, Isoetes howellii Engelmann. Under natural conditions free-CO(2) level in the water was highest at 0600 hours and (14)CO(2) assimilation rates in I. howellii were also highest at this time. After 0900 hours there was a similar pattern in (a) rate ...
متن کاملRoot environment acidity as a regulatory factor in ammonium assimilation by the bean plant.
Previous experiments have revealed a much greater efficiency of ammonium utilization by bean plants (Phaseolus vulgaris L.) when the acidity of the ambient medium was maintained at near-neutral conditions with carbonates or hydroxides. The present investigation, in which (15)N-labeled ammonium was used, permitted an assessment of the origin of nitrogen in tissue nitrogen pools with and without ...
متن کاملPotential Enhancement of Plant Iron Assimilation by Microbial-Induced Root Exudation of Phenolic Compounds
Iron (Fe) deficiency in crop plants is a modern agricultural problem worldwide. Although multiple strategies have been evolved to improve Fe assimilation, some plant species, especially dicots and nongraminaceous monocots (strategy I plants), cannot avoid Fe deficiency in low Fe-availability soils. It is well documented that graminaceous plants (strategy II plants) employ the chelationbased Fe ...
متن کاملThe assimilation of carbon by Chloropseudomonas ethylicum.
1. The enzymes in ultrasonically prepared extracts of Chloropseudomonas ethylicum were studied to elucidate how this organism assimilates acetate and carbon dioxide and why it cannot grow with either of these two compounds alone. 2. Such extracts can (i) convert acetate and oxaloacetate into alpha-oxoglutarate, (ii) convert oxaloacetate into succinyl-CoA, (iii) convert phosphopyruvate into 3-ph...
