Increased disturbance of terrestrial ecosystems in recent years for purposes of mineral extraction has created interest in development and optimization of reclamation methodologies for these lands. Currently, criteria for judging surface mine reclamation success, or progress toward reclamation goals, predominantly rely on aboveground indicators that fail to account for the abundance and composi...

The recent resurgence of the late blight pathogen, Phytophthora infestans (Mont.) de Bary, as a major agricultural threat, as well as the associated changes in genetic complexity of this organism, have necessitated careful scrutiny and characterization of populations of P. infestans so that appropriate control methods can be implemented. Several techniques for molecular and genetic characteriza...

Assessment of free fatty acid (FFA) concentration and isotopic enrichment is useful for studies of FFA kinetics in vivo. A new procedure to recover the major FFA from plasma for concentration and isotopic enrichment measurements is described and validated. The procedure involves extraction of plasma lipids with hexane, methylation with iodomethane (CH(3)I) to form fatty acid methyl esters (FAME...

Fatty acids are widely occurring in natural fats and dietary oils and they are known to have antibacterial and antifungal properties. However, little is known on the antibacterial and antifungal properties of the blindyour-eye mangrove (Excoecaria agallocha) and this study for the first time determines the fatty acid composition and the antibacterial and antifungal activities of Fatty Acid Meth...

Fatty acid methyl esters, which are used as biodiesel, can be produced by esterification of fatty acids in supercritical methanol. However, a reverse reaction, esters hydrolyzed to regenerate due the presence water, is making it difficult reduce content sufficiently. In this study, oleic was treated methanol at 310 °C/20 MPa with flow-type reactor adding formate improve yield ester. As result, ...

Increases in biodiesel prices remains a challenge, mainly due to the high cost of conventional oil feedstocks used during production and challenges associated with using homogeneous catalysts process. This study investigated conversion waste-derived black soldier fly (BSF) maggot feedstock over hydroxy sodalite (HS) zeolite synthesized from waste coal ash (CFA) production. The product prepared ...

The objective of this work was to establish fixed bed sorption enhanced reactors (SER) and simulated moving bed reactors (SMBR) for the production of high purity biodiesel (fatty acid methyl ester, FAME) using esterification reactions between fatty acids (FA) in used oils and methanol. This study has demonstrated that these processes have tremendous potential in terms of overcoming the low conv...

Oil methanolysis over modified CaO catalysts was studied to assess the catalytic performance and define an appropriate kinetic model. by commercial glycerol a deep eutectic solvent (DES), choline chloride : (ChCl Gly), obtain catalytically active complexes of glycerol. The main goal investigate effect obtained on reaction rate fatty acid methyl ester (FAME) content describe variation triacylgly...

Increased energy consumption and the depletion of petroleum reserves have pushed up oil prices globally. Diminishing reserve is another global risk factor. ProducingBiodiesel vegetable oils animal fat by transesterification can be a considerable alternative. In this study, biodiesel produced from waste cooking method with methanol in presence HCl as catalyst. Biodiesel production begins mixing ...

The olive tree (Olea europaea L.) fruit oil attracts widespread interest because of its high content monounsaturated fatty acids. However, a neglected area in the field is edaphoclimatic factors impact, which poorly understood. Bearing this mind, purpose investigation was to evaluate impact conditions on acids’ composition. Therefore, we have investigated acids methyl ester (FAME) profile 38 mo...
