1. GASES DE NITROGÊNIO REATIVO COMO PRECURSORES DO AEROSSOL ATMOSFÉRICO: REAÇÕES DE FORMAÇÃO, PROCESSOS DE CRESCIMENTO E IMPLICAÇÕES AMBIENTAIS
The increased emissions of reactive nitrogen gases from anthropogenic sources to the atmosphere has been pointed out as responsible for triggering a series of environmental problems at the local, regional, and global scale. Among the many consequences associated with the excess of reactive nitrogen in the environment is the increase of atmospheric aerosol fo

4. Evaluation of CO2 Biofixation and Biodiesel Production by Spirulina (Arthospira) Cultivated In Air-Lift Photobioreactor
ABSTRACT Spirulina is a microalgal genre that has the capacity to produce various bioproducts with applications in several areas including the energy sector. The study aimed to assess the ability of CO2 biofixation, biodiesel and other biocompounds production by Spirulina sp LEB 18 cultured in air-lift photobioreactor. The microalgae presented a rich macronu

5. The effect of micronized corn fiber on body weight, glycemia, and lipid metabolism in rats fed cafeteria diet
Abstract During corn industrial dry milling, a residue rich in dietary fibers is generated. This study aimed to evaluate the effects of micronized corn fiber (MCF) as part of a cafeteria diet in the macronutrient metabolism and body weight. Wistar male rats, with initial body weight of 249 ± 14 g (n = 13), received AIN-93M diet (Group 1) or cafeteria diet

8. ESTIMATE OF NUTRITIONAL STATE OF FLOODED RICE / ESTIMATIVA DO ESTADO NUTRICIONAL DE ARROZ IRRIGADO POR ALAGAMENTO
The difficulty to predict the intensity of soil properties alterative by soil flooding frequently makes the interpretation of the soil analysis results inaccurate when considering nutrients availability to the plants. Complementary methods of soil analysis, as leaf tissue analysis, chlorophyll meter and the leaf color chart can be used in order to estimate p

11. Molecular characterization of nitrate reductase gene and it expression in the marine red alga Gracilaria tenuistipitata (Rhodophyta) / Aspectos moleculares de nitrato redutase da macroalga marinha Gracilaria tenuistipitata (RHODOPHYTA): seqüenciamento do gene e estudo da expressão do RNA mensageiro
In the marine environment, the major source of nitrogen is nitrate, which must be reduced before incorporation into organic compounds, such as amino acids and nitrogen bases (purines and pyrimidines). The first enzyme that participates in the nitrogen assimilation process is nitrate reductase (NR), which is responsible for the conversion of nitrate to nitrit

12. Nitrogen Assimilation and Protein Synthesis in Wheat Seedlings As Affected by Mineral Nutrition. I. Macronutrients 1
Deficiencies of each macronutrient (N, P, K, Ca. Mg, S, and Fe) decreased the specific activity of nitrate reductase from Triticum aestivum L. seedlings. Nitrate content was decreased by N, P, K, Ca, and Mg deficiencies and unaffected by S and Fe deficiencies. Glutamic acid dehydrogenase activity was decreased by N, P, and S deficiencies, unchanged by K defi
