Research ArticleOpen accessIn the abstractOPTIMIZATION OF ALKALINE PROTEASE PRODUCTION BY STREPTOMYCES AMBOFACIENS IN FREE AND IMMOBILIZED FORMNayera A.M. Abdelwahed, Enas N. Danial, Noura El-Ahmady El-Naggar, Asem A. MohamedOptimization of alkaline protease production by Streptomyces ambofaciens NRRL 2420 in free and immobilized form was investigated using submerged fermentation technique. The optimum conditions for maximum alkaline protease production 342 unit mL-1 were 30°C at pH 8.5 and incubation time 96 h in free cell cultures using starch 20 g L-1 as carbon source and yeast extract 5 g L-1 … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 1 · 28 Dec 2013 · 8,131 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification of Pseudozyma hubeiensis Y10BS025 as a Potent Producer of Glycolipid Biosurfactant Mannosylerythritol lipidsMartha Sari, Atit Kanti, I. Made Artika, Wien KusharyotoMannosylerythritol Lipids (MEL’s) are glycolipid biosurfactants that contain 4-O-β-D-mannopyranosyl-meso-erythritol as a hydrophilic moiety and fatty acids as a hydrophobic moiety. MEL’s are abundantly produced by several kinds of microorganism and are one of the most promising biosurfactants currently known. The search for a novel endogenous producer of MEL’s was undertaken based on the available collection of the yeast strains from … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 4 · 20 Dec 2013 · 8,103 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancement of Nutritional Quality of Wheat (Triticum aestivum) by Metabolic Engineering of Isoflavone PathwayAhmed Mohamed El-Shehawi, Abdelmegid Ibrahim Fahmi, Mona Mohamed Elseehy, Hesham Ahmed NagatyIsoflavones are large group of secondary metabolites produced in legumes such as soybeans. They have essential biological functions as nutraceutical and health functions for human. They are involved in plant resistance to biotic and abiotic stresses, symbiotic relationship with nitrogen-fixing organisms and plant competition (allelopathy). In this report, isoflavonoids were expressed in wheat (Triticum aestivum) via introducing the key enzymes … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 4 · 20 Dec 2013 · 7,139 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Phosphorus Application with Avail on Growth and Yield of Winter Wheat in Southeastern Coastal PlainsPawel WiatrakPhosphorus (P) application with Avail may affect plant growth and grain yields of winter wheat (Triticum aestivum L.) under dryland conditions. The objective of this study was to determine the effects of two P application rates (45 and 90 kg ha-1) with and without Avail polymer on growth and yields of dryland winter wheat near Blackville, SC from 2010 to … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 3 · 16 Sep 2013 · 7,141 accessesView PDFCite
Research ArticleOpen accessIn the abstractCombustion, Performance and Emission Characteristics of Diesel Engine with Neem Oil Methyl Ester and its Diesel BlendsL. Prabhu, S. Sathish Kumar, M. Prabhahar, K. RajanBiodiesel, an alternative fuel is derived from the fats of animals and plants. As energy demands increase and fossil fuels are limited, research is directed towards alternative renewable fuels. The main advantages of using this alternative fuel are its renewability, biodegradability and better quality of exhaust gases. It is technically competitive and environmentally friendly alternative to conventional petro-diesel fuel for … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 7,264 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnaerobic Transformation of Biodegradable Waste; Simultaneous Production of Energy and FertilizerAmirhossein Malakahmad, Syazana Nasrudin, Noor Ezlin Ahmad Basri, Shahrom Md ZainAlmost 40% of the total waste produced in developing countries is made of biodegradable waste. Typically the waste including the biodegradable portion is transported to the so-called landfills without any segregation process, treatment and utilization in advance. Although mitigation practices such as source reduction, reuse and recycle are essential and required to be practiced in any integrated waste management plan, … …American Journal of Environmental Sciences, Vol. 9, Issue 2 · 10 Mar 2013 · 7,379 accessesView PDFCite
