Research ArticleOpen accessIn the abstractSolid State Fermentation of Mexican Oregano (Lippia Berlandieri Schauer) WastePaola Melendez-Renteria, Virginia Nevarez-Moorillon, R. Rodriguez-Herrera, Cristobal Noe AguilarProblem statement: Mexican oregano is recognized for their aromatic characteristics and flavor quality. Principal products obtained from the plant and marketing are the leaves and essential oil; however the extraction of the essential oil generates large amounts of agro industrial wastes; that can be used as support-substrates in Solid-State Fermentations (SSF). Approach: In this study a fungal bioprocess, as solid … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 3 Mar 2012 · 8,475 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCellulolytic Enzymes Production by Solid State Culture Using Pecan Nut Shell as Substrate and SupportMiguel A. Medina-Morales, José L. Martínez-Hernández, Heliodoro de la Garza, Cristóbal Noé AguilarProblem Statement: Great interest in the use of lignocellulosic biomass is increasing in order to diminish the accumulation of residues, such as pecan nut shells. One of the alternatives is the fungal degradation of these residues. Approach: The capacity of Trichoderma (coded as T1, T2 and T3) strains to produce cellulase and xylonite was evaluated. Results: Pecan nut shell fibers … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 6 Jun 2011 · 8,023 accessesView PDF Cite

Research ArticleOpen accessIn the abstractValidated High Performance Liquid Chromatographic Method for Analysis of Fenvalerate Pesticide in Chilies by QuEChERS Extraction Cleanup and High Liquid ChromatographyAhmed Ambarak Altorshani, Nor Kartini Abu Bakar, Eltayeb Elamin M. EidProblem statement: Contamination associated with pesticide use has increased as well, adversely impacting the environment and causing human health risks through residues on food. Approach: This study reports the extraction of Fenvalerate (FE) in chilies using QuEChERS based on High Performance Liquid Chromatography (HPLC) describes a simple, fast and inexpensive method. The chillie was extracted with acetonitrile Aliquots were cleaned-up … …American Journal of Applied Sciences, Vol. 7, Issue 12 · 31 Dec 2010 · 7,163 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUse of a Mixture of Thermophilic Enzymes Produced by the Fungus Thermoascus aurantiacus to Enhance the Enzymatic Hydrolysis of the Sugarcane Bagasse CelluloseJ. R. Monte, W. Carvalho, A. M. F. MilagresProblem statement: The production of hydrolytic enzymes by T. aurantiacus has been performed under solid-state fermentations using lignocellulosic materials. The influences of the inoculum size and of the fermentation medium on the production of hemicellulases and cellulases were studied. Filtrates from the cultures were used to hydrolyze a pulp of sugarcane bagasse and the produced enzymes were shown to be … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 4 · 13 Dec 2010 · 9,212 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFungal Culture Systems for Production of Antioxidant Phenolics Using Pecan Nut Shells as Sole Carbon SourceMiguel A. Medina, Ruth E. Belmares, Antonio Aguilera-Carbo et al.Problem statement: Many agro-industrial wastes have little or none utilization, when these materials could be a very rich source of several value-added compounds, such as: the pecan nut shells, which contain Antioxidant Phenolic (AP) molecules like tannins. Approach: In this study, a bioprocess for the liberation of AP from Pecan Nut Shells (PNS) was described. A chemical characterization of raw … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 8,042 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAdsorption of Pb(II) on Spent Leaves of Green and Black TeaAntonio Zuorro, Roberto LavecchiaProblem statement: In recent years much attention has been focused on the use of biomass residues as low-cost adsorbents for the removal of heavy metal ions from contaminated waters. Spent tea leaves, an abundantly available material that is currently disposed of as a solid waste, are potentially suitable for such applications. Approach: To provide some information on the adsorption properties … …American Journal of Applied Sciences, Vol. 7, Issue 2 · 28 Feb 2010 · 9,588 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffective Thermophilic Composting of Crop Residues for Inactivation of Tobacco Mosaic VirusA.E. Ghaly, F. Alkoaik, A. Snow, R. SinghAn effective thermophilic composting bioreactor, in which a homogenous distribution of temperature was maintained at 63-65°C by the addition of a bioavailable carbon and low mixing, was developed. The bioreactor operated on a mixture of tomato plant residues-wood shavings-municipal solid waste compost infected with tobacco mosaic virus (TMV). The initial C: N ratio and moisture content of the compost mixture … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 3 · 30 Sep 2006 · 6,963 accessesView PDF Cite
