Research ArticleOpen accessIn the abstractDevelopment and Implementation of Effective Schemes for the Use of Mineral Fertilizers in the Forest-Steppe Zone of the North Kazakhstan RegionZh. A. Nokusheva, E. Ye. Kantarbayeva, M. B. Ormanbetov et al.Nitrogen fertilizers in liquid form have become the most common ones in recent years. Since North Kazakhstan is located in a zone of risky farming, liquid fertilizers are a very productive solution. The purpose of the study was to develop and evaluate the implementation of effective schemes for the use of mineral fertilizers in the forest-steppe zone of the North … …OnLine Journal of Biological Sciences, Vol. 23, Issue 3 · 5 Jun 2023 · 5,300 accessesView PDFCite
Research ArticleOpen accessIn the abstractAcer Buergerianumas a New Resource for the Extraction of Corilagin: Determination of Corilaginin Different Cultivars of A. Buergerianumby UPLCQian Qiao, Chong Wu, Jiangyong Wang et al.Corilagin is a promising anticancer drug candidate. Acer nikoense and A. ammonium are both known to contain corilagin. To explore whether corilagin occurs in congeneric species and to fully develop the medicinal value of maple, the corilagin content in different varieties of maple was determined by Ultrahigh-Performance Liquid Chromatography (UPLC). Acer buergerianum leaves contained corilagin and the corilagin content in … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 2 · 12 May 2022 · 5,710 accessesView PDFCite
Research ArticleOpen accessIn the abstractCocoa-Butter-Equivalent Production from Yarrowia lipolytica by Optimization of Fermentation TechnologyLina Zhao, Bo Li, Dan Xiong et al.In order to obtain the optimal control point for single-cell lipid production with fatty acid profile similar to cocoa butter, this study explored the effects of carbon source, nitrogen source, temperature, sterculic acid methyl ester, cobalt on cell growth and lipid accumulation of Yarrowia lipolytica. Glycerol and ammonium tartrate-yeast extract were chosen as carbon source and nitrogen source for production … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 4 · 29 Dec 2016 · 9,291 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Light Exposure and Nitrogen Source on the Production of Oil from Freshwater and Marine Water MicroalgaeMariam Al Hattab, Abdel GhalyThe biomass yield and oil content of Chlorella saccharophila (freshwater) and Tetraselmis suecica (marine) microalgae were investigated using various nitrogen source (ammonium nitrate, ammonium phosphate, ammonium sulfate and combination of nutrients) at various light durations (9, 16 and 24 h). NaHCO3 was used as the carbon source. The nitrogen concentration, temperature and pH were maintained at 70 mg/L, 22°C and … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 4 · 8 Dec 2014 · 7,270 accessesView PDFCite
Research ArticleOpen accessIn the abstractFUNCTIONAL PROPERTIES OF PROTEIN CONCENTRATE FROM BLACK COWPEA AND ITS APPLICATIONAnuchita Moongngarm, Sirinapa Sasanam, Watcharee Pinsiri et al.Black cowpea (Vigna unguiculata L. Walp.) is high in protein, which makes it suitable for use as a protein supplement in food products. However, direct application of cowpea flour in food products is limited as it may affect some quality aspects of foods. Protein concentrate and isolate are a form of the protein that is gaining interest in industry. Therefore, … …American Journal of Applied Sciences, Vol. 11, Issue 10 · 29 Nov 2014 · 6,409 accessesView PDFCite
Research ArticleOpen accessIn the abstractCOMPARING GIBBS ENERGY RELATIONSHIPS FOR AMMONIA VOLATILIZATIONS FROM AGRICULTURAL SOILS FOR POTATO PRODUCTIONGuodong Liu, Yuncong Li, Ashok AlvaSoil drought, that can be enhanced by global warming increases ammonia (NH3) volatilization. This laboratory study was conducted with two soils: Krome Gravelly Loam (KGL) from Florida and Warden Silt Loam (WSL) from Washington State and two fertilizers: Ammonium sulfate [(NH4)2SO4] or ammonium nitrate (NH4NO3). Two water regimes including 20 and 80% Field Capacity (FC) were used at 20°C which … …American Journal of Environmental Sciences, Vol. 10, Issue 1 · 8 Feb 2014 · 7,493 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Diurnally Cyclic Temperature on the Performance of a Continuous Mix Anaerobic DigesterAbdel E. Ghaly, Mariam T. Al HattabProblem statement: Concentrated livestock production is a major contributor to environmental problems through the production of large quantity of husks on relatively small land area. Anaerobic digestion represents a valuable means of cover by these husks into methane while reducing manure pollution problems. Methodology: An experimental apparatus, including data acquisition and control system, was developed and used to investigate the … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 4 · 19 Jan 2012 · 9,230 accessesView PDFCite

Research ArticleOpen accessIn the abstractEffect of Enhancing Urea-Humic Acid Mixture with Refined Acid Sulphate SoilMohd Taufik Mohd Yusuff, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: Acid Sulphate Soil (ASS) is a problem soil partly because of its high acidity. This low pH could be exploited to reduce ammonia loss from urea by reducing soil microsite pH. The use Humic Acid (HA) to control ammonia loss from urea has been reported but the cost of this material is high. This laboratory study compared the … …American Journal of Applied Sciences, Vol. 6, Issue 11 · 30 Nov 2009 · 7,282 accessesView PDFCite
