Research ArticleOpen accessIn the abstractReaction Kinetics of Versatile Peroxidase for the Degradation of Lignin CompoundsN. Busse, D. Wagner, M. Kraume, P. CzermakThe H2O2-dependent degradation of adlerol by a crude versatile peroxidase from Bjerkandera adusta, a new ligninolytic enzyme, was investigated. Adlerol (1-(3,4-dimethoxyphenyl)-2-(2-methoxyphenoxy)-1,3-propanediol)) is a non phenolic β-O-4 dimer whose structural architecture represents the most abundant unit (50-65%) of the valuable renewable biopolymer lignin. Lignin removel plays a key role in utilizing lignocellulosic biomass in biorefineries. Steady state analyses in the µL … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 4 · 20 Dec 2013 · 9,263 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 · 7,259 accessesView PDFCite
Research ArticleOpen accessIn the abstractSoft Path Water Management in Dry and arid Regions of the Arabian Peninsula by Rainwater HarvestingM. T. Amin, A. A. Alazba, U. ManzoorSaudi Arabia has limited renewable water resources and the groundwater is the main source of water in Saudi Arabia which. With an arid climate, it receives about 50-100 mm/year of rainfall in Central, Eastern and Northern regions. There are few studies investigating the future regional climate change and some has predicted a decrease in precipitation but with extreme climate events … …American Journal of Environmental Sciences, Vol. 9, Issue 2 · 13 Apr 2013 · 7,852 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhycoremediation and the Potential of Sustainable Algal Biofuel Production using WastewaterAdel A. Fathi, Mohamed M. Azooz, Mohamed A. Al-FredanWastewater remediation by microalgae is an eco-friendly process with no secondary pollution as long as the biomass produced is reused and allows efficient nutrient recycling. This study was undertaken to evaluate the remediation of wastewater by the green alga Chlorella vulgaris and the potential of these alga (biomass) to produce sustainable biofuel. The results shows that the cultivation of green … …American Journal of Applied Sciences, Vol. 10, Issue 2 · 27 Feb 2013 · 7,536 accessesView PDFCite
Research ArticleOpen accessIn the abstractPotential Applications of Chitosan Nanoparticles as Novel Support in Enzyme ImmobilizationHoda Jafarizadeh Malmiri, Mohammad Ali Ghaz Jahanian, Aydin BerenjianChitosan is an attractive natural biopolymer from renewable resources with the presence of reactive amino and hydroxyl functional groups in its structure. Due to the good biocompatibility of chitosan, it can be used in magnetic-field assisted drug delivery, enzyme or cell immobilization and many other industrial applications. In the past decade, nanotechnology has been a considerable research interest in the … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 4 · 25 Dec 2012 · 11,302 accessesView PDFCite
Research ArticleOpen accessIn the abstractAvailability and Physical Properties of Residues from Major Agricultural Crops for Energy Conversion Through Thermochemical ProcessesYaning Zhang, A. E. Ghaly, Bingxi LiPlant residues from the major agricultural crops (wheat, rice, corn, soybean, sugarcane, coffee and cotton) are abundantly available renewable resources that can be used to supply energy through thermochemical conversion processes. The available amounts of plant residues from these crops and their physical properties (moisture content, particle size, bulk density and porosity) were determined. The annual residues from the wheat, … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 3 · 4 Aug 2012 · 9,663 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhysical Properties of Wheat Straw Varieties Cultivated Under Different Climatic and Soil Conditions in Three ContinentsYaning Zhang, A. E. Ghaly, Bingxi LiOver 500 million tonnes of wheat straw are produced annually worldwide, the majority of which are burnt in the field causing significant environmental and health problems as well as serious traffic accidents in addition to loss of a valuable resource. Wheat straw is abundantly available and renewable and can be used as an energy source in gasification and combustion systems. … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 2 · 26 Jun 2012 · 21,088 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhysical Properties of Corn ResiduesYaning Zhang, A. E. Ghaly, Bingxi LiCorn residues (cobs, leaves and stalks) are abundantly available renewable materials that can be used as an energy source in gasification and combustion systems.
