1. Effects of nitrogen supplementation on Saccharomyces cerevisiae JP14 fermentation for mead production
Abstract Honey must supplementation is necessary for mead production due to the deficiency in nitrogen materials in this feedstock, despite its high fermentative sugar content. The nitrogen limitation can halt or slow fermentation and lead to the production of unpleasant sensorial compounds, such as sulfur derivatives. The yeast JP14, a Saccharomyces cerevis

2. Preharvest nitrogen application affects quality and antioxidant status of two tomato cultivars
ABSTRACT Intensive horticultural crop production usually involves challenges from excessive application of fertilizer, mainly nitrogen (N). The effect of N fertilizer on the fruit quality and antioxidant status of two cherry tomato cultivars (Caballero and Victoria) under greenhouse conditions was performed. Nitrogen treatments were applied ranging from cond

3. Fruit quality of pineapple ‘Vitória’ under macronutrients and boron deficiency
Resumo Objetivou-se avaliar a influência das deficiências de macronutrientes e de boro nas características físico-química dos frutos de abacaxizeiro da cultivar Vitória. O delineamento experimental foi em blocos ao acaso, com oito tratamentos (solução completa, -N, -P, -K, -Ca, -Mg, -S e -B) e seis repetições. A condução do experimento foi de ou

4. Clinical Trials in Mitochondrial Disease: An Update on EPI-743 and RP103
Abstract Mitochondrial dysfunction results in the production of an abnormally high amount of reactive oxygen and nitrogen species, which results in redox imbalance and glutathione deficiency. Therapeutics such as EPI-743 (?-tocotrienol quinone) and RP103 (cysteamine bitartrate) have the theoretical potential to improve redox imbalance by increasing intracell

5. NITROGEN AND ORGANIC FERTILIZATION ON GRAPEVINE PRODUCTIVITY IN THE BRAZILIAN SEMIARID REGION
RESUMO A adubação nitrogenada na videira apresenta-se como um fator limitante na produção, visto que seu excesso ou deficiência são capazes de propiciar alterações na quantidade e qualidade final dos frutos. Assim, o objetivo deste trabalho foi avaliar os parâmetros produtivos da videira 'Isabel Precoce' submetida a adubação nitrogenada e orgânic

6. Genome-wide identification, classification and transcriptional analysis of nitrate and ammonium transporters in Coffea
Abstract Nitrogen (N) is quantitatively the main nutrient required by coffee plants, with acquisition mainly by the roots and mostly exported to coffee beans. Nitrate (NO3–) and ammonium (NH4+) are the most important inorganic sources for N uptake. Several N transporters encoded by different gene families mediate the uptake of these compounds. They have an

7. Research on the quality of the wine grapes in corridor area of China
The corridor area of Gansu Province is one of the most important wine grape growing regions in China, and this strip of land results in a significant difference in terms of terroir between its regions. Chemical composition and antioxidant capacity of the main wine grape varieties (Vitis vinifera L.) cultivated in the corridor area of Gansu Province in northw

8. Waterlogging-induced changes in fermentative metabolism in roots and nodules of soybean genotypes
Waterlogging blocks the oxygen supply to the root system which inhibits respiration, and greatly reduces the energy status of cells that affect important metabolic processes. This study evaluated fermentative metabolism and carbohydrate contents in the root system of two soybean (Glycine max L. Merril) genotypes under hypoxic and post-hypoxic conditions. Nod

9. Agrowaste-based Polyhydroxyalkanoate (PHA) production using hydrolytic potential of Bacillus thuringiensis IAM 12077
The study identified the innate enzymatic potential (amylase) of the PHB producing strain B.thuringiensis IAM 12077 and explored the same for cost-effective production of PHB using agrowastes, eliminating the need for pretreatment (acid hydrolysis and/or commercial enzyme). Comparative polyhydroxyalkanoate (PHA) production by B. thuringiensis IAM 12077 in bi

10. Chlorophyll and carbohydrates in Arachis pintoi plants under influence of water regimes and nitrogen fertilization
In this experiment the chlorophyll and carbohydrate contents of Arachis pintoi were evaluated to verify if the presence of nitrogen in the soil could contribute to the effectiveness of the establishment of this legume. The design was completely randomized, in a 4 × 4 factorial arrangement, with four N rates (0, 40, 80 and 120 kg ha-1) and four irrigation le

11. Effect of water stress on the growth of Arachis pintoi plants under different nitrogen levels
The objective was to evaluate the growth of Arachis pintoi fertilized with nitrogen and water deficiency conditions. The study was developed in a 4 × 4 factorial arrangement with four nitrogen levels (0, 40, 80 and 120 kg N/ha) and four irrigation levels (25, 50, 75 and 100% of field capacity), in a completely randomized experimental design, with four repli

12. Interação entre os estresses de nitrogênio e disponibilidade hídrica no fracionamento isotópico de 13C e na produtividade em soqueira de cana-de-açúcar / Interaction between nitrogen and water availability over isotopic discrimination of 13C and ratoon sugarcane production
The sugarcane crop has an important contribution in sub tropical and tropical regions around the world, which Brazil the major producer of sugarcane crop, sugar and ethanol. However, the sugarcane yield is still very low in many regions of this country, mainly due to water stress and nitrogen supply. Understand the loss sugarcane production related with wate
