Nitrogen metabolism in Corynebacterium glutamicum ATCC 13032
… much research has been directed at analyzing nitrogen metabolism in this bacterium. In particular, our research focused on investigating the regulation of nitrogen assimilation. Initially, we searched for homologs of the Streptomyces glnR, glnII, and glnE genes in C. glutamicum. These studies, …

Regulation of nitrogen metabolism in vibrio alginolyticus
… coordinately induced by histidine. The inducible nitrogen catabolic enzymes arginase, alanine dehydrogenase and histidase were not subject to nitrogen catabolite repression. Various amino acids and ammonium ions stimulated the production of histidase and arginase. Urocanase and formiminoglutamate …

Prochlorococcus genetic transformation and genomics of nitrogen metabolism
… gyres where major plant nutrients such as nitrogen (N) and phosphorus (P) are at nanomolar concentrations. Nitrogen availability controls primary productivity in many of these regions. The cellular mechanisms that Prochlorococcus uses to acquire and metabolize nitrogen are thus central to …

Nitrogen Metabolism and Solvent Production in Clostridium Beijerinckii Nrrl B593
… acetobutylicum and Clostridium beijerinckii, are nitrogen-fixing organisms and both nitrogen-fixation and alcohol production (n-butanol, isopropanol and ethanol) are reductant-dependent processes, the effect of nitrogen fixation on the onset and progression of solvent production in C. beijerinckii …

Coordination of Carbon Dioxide and Nitrogen Metabolism in Rhodobacter sphaeroides
Studies of metabolism usually characterize a system in isolation without a whole-cell focus on interactions with other metabolic pathways. In this work, two different metabolic pathways of the nonsulfur purple bacterium <i>Rhodobacter sphaeroides</i> were studied simultaneously <i>in vivo</i> to …

Phosphorus and nitrogen metabolism in soybeans as influenced by potassium
The effect of K on P and N metabolism in soybean seedlings, Glycine max, Var. Dorman, was studied in two greenhouse experiments. Yield, nutrient uptake and changes in the distribution of cellular P and N compounds served as criteria for evaluating K effects. The yield increased exponentially with …

Excretory nitrogen metabolism in the Chinese soft-shelled turtle, pelodiscus sinensis
… stress, emersion and acute ammonia toxicity, on nitrogen metabolism and excretion in the Chinese soft-shelled turtle Pelodiscus sinensis. Pelodiscus sinensis is ureogenic and primarily ureotelic in freshwater. Our results reveal that a major portion of the urea was excreted through the …

The Effect of Insulin on the Nitrogen Metabolism of Teleost Fishes
… the action of insulin in controlling the overall metabolism of nitrogen in the goldfish (Carassius auratus). Morphological investigations of the Islets of Langerhans have shown them to be closely associated with the ducts of the diffuse exocrine pancreas and thus are present throughout the …

The relationship between Protein Source and Nitrogen Metabolism in the Trout
… In the first series of experiments classical nitrogen balance techniques were used. From these, MFN was found to be 175 mg N/100g diet and EUN 12.37 mg N/100g fish/day. Using this data, true NPU's were determined at various levels of N intake ranging from 36 to 140 mg/100g fish/ day. True NPU …

Regulatory mechanisms underlying C3 carbon and nitrogen metabolism under elevated CO2
… regulatory factors influencing carbon (C) and nitrogen (N) metabolism in C3 plants under eCO2 through inferences made in Soybean and Arabidopsis. This aim is achieved threefold. The first aim involves optimizing protein translation dynamics in C3 plants. It is essential to understand the …

NITROGEN METABOLISM AND IRON REDUCTION IN AQUASPIRILLUM MAGNETOTACTICUM (NITRATE, FIXATION, MAGNETIC BACTERIUM)
… with NO(,3)('-) or NH(,4)('+) as the sole nitrogen source. Cell yields varied directly with NO(,3)('-) concentration under microaerobic conditions. Products of NO(,3)('-) reduction by growing cells included NH(,4)('+), N(,2)O, NO, and N(,2) but not NO(,2)('-) or NH(,2)OH. The inclusion of …

Nitrogen metabolism in meatmaster sheep fed brewers grain as a supplementary source of protein
This study aimed to examine how nitrogen metabolism in sheep is affected when brewers’ grains are added to diet as a supplementary protein source. Eight Meatmaster rams (average live weight 30 ± 3.2 kg; approximately 6 months old) were randomly allocated to four iso-energetic and iso-nitrogenous …
