Phospholipase C catalyzes the hydrolysis of the sn-3 phosphate head group in phospholipids including phosphatidylcholine, phosphatidyletanolamine, and phosphatidylserine with the formation of 1,2-diacylglycerol and water soluble phosphate esters phosphorylcholine, phosphorylethanolamine, and phosphorylserine. Phospholipase C from P. pastoris is intended for use in the refining of soybean oil an...

bioremediation, the process by which microorganisms degrade organic compounds to non-toxic or less toxic substances, has been widely used for cleanup of coastal ecosystems after oil spills. in this study, the hydrocarbon degradation rate and half lives in three bioremediation strategies (natural attenuation, biostimulation, and bioaugmentation) were compared in weathered crude oil (wco) contami...

Soybeans are subject to potential contamination from toxic weed seeds during harvest, transportation and storage. The more common foreign seeds include those from jimsonweed, cocklebur, nightshade, cowcockle, corncockle, morning glory, castor, pokeweed, and crotalaria. This review addresses itself to the chemistry and toxic principles of these contaminants. Since jimsonweed seeds are probably t...

The present investigation was conducted to study the effect of processing (soaking and germination) and cooking methods (ordinary cooking and autoclaving) on the chemical composition, sugars and phytic of two varieties soybean seeds, Giza, 21 and Giza, 35. The processing and cooking methods caused increase in both protein and crude fiber contents. Meanwhile, crude oil and carbohydrates contents...

Soybean lecithin containing a mixture of phospholipids (PLs) is an important co product obtained during soybean oil refining. Saturated rich PLs find several applications in food, cosmetic and pharmaceutical areas. The present study reports a simple, rapid, efficient and continuous hydrogenation process using 10% Pd/C catalyst at various temperatures and pressures. Degree of hydrogenation was m...

Mudflats are ecologically important habitats that are susceptible to oil pollution, but intervention is difficult in these fine-grained sediments, and so clean-up usually relies on natural attenuation. Therefore, we investigated the impact of crude oil on the bacterial, diatom and archaeal communities within the upper parts of the diatom-dominated sediment and the biofilm that detached from the...

Germination rate in contaminated soils cannot be used as the sole indicator to select suitable species for phytoremediation trials, since it does not predict the plant development after germination. As a result, most screening tests for selection of specie with phytoremediation potential to treat contaminated soils include germination rate and biomass production. These screenings take several m...

Crude oil spilled from the Herbaysprit in Oecember 2007 and contaminated Tae Ann Sound shoreline. A weathered oiled sediment collected at the spill area (Tai Ann beach) from 3 months to 12 months after the spil l. The fingerprinting and data interpretation techniques oil spill characterization and identification studies and environmental investigations discussed indude oil spill identification ...
