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...

Preventing oxidative deterioration of fish oil is a significant challenge for the food industry. Natural antioxidants are widely incorporated into foods to prevent oxidation and extend shelf life. Vine tea (Ampelopsis grossedentata) extract has been shown to have antioxidant activity in vegetable oils, but the efficacy in fish oil is unknown. The goal of our study was to test the antioxidant ac...

Supercritical fluid extraction (SFE), which has received much interest in its use and further development for industrial applications, is a method that offers some advantages over conventional methods, especially for the palm oil industry. SC-CO₂ refers to supercritical fluid extraction (SFE) that uses carbon dioxide (CO₂) as a solvent which is a nontoxic, inexpensive, nonflammable, and nonpoll...

This paper presents an experimental program on rapid chloride permeability test on lightweight concrete produced from oil palm clinker aggregates. Oil palm clinker is obtained from by-product of palm oil milling. Utilising oil palm clinker in concrete production not only solves the problem of disposing this solid waste but also help to converse natural resources. The parameter of investigation ...

Crude oil plays an increasingly significant role in world economic development and also in the generation of wealth since nearly two-thirds of the world’s energy consumption comes from crude oil and natural gas. Worldwide consumption of crude oil exceeds $500 billion—roughly 10% of US GDP and crude oil is also the world’s largest and most actively traded commodity, accounting for about 10% of t...

Oxidative stress is an important etiology of chronic diseases and many studies have shown that natural products might alleviate oxidative stress-induced pathogenesis. The study aims to evaluate the effect of Argan oil and Syzygium aromaticum essential oil on hydrogen peroxide (H₂O₂)-induced liver, brain and kidney tissue toxicity as well as biochemical changes in wistar rats. The antioxidant co...

Introduction: In this study, the chemical composition and antimicrobial activity of essential oil of Ziziphora clinopodiodes and its potential application as a natural preservative in reducing the indigenous microbial population of hamburger were investigated. Method: Essential oil of Ziziphora clinopodiodes cultivated in Iran was obtained by Hydro-distillation method (HDM). Chemical compositio...

Were evaluated natural attenuation, biostimulation and bioaugmentation on the degradation of total petroleum hydrocarbons (TPH) in soils contaminated with diesel oil. Bioaugmentation showed the greatest degradation in the light (C12 C23) fractions (72.7%) and heavy (C23 C40) fractions of TPH (75.2%) and natural attenuation was more effective than biostimulation. The greatest dehydrogenase activ...

tea and sesame seed oils extracted by different methods (including supercritical fluid extraction (sfe), at a pressure of 350 atm, a temperature of 60oc, a static extraction time of 20 minutes, a dynamic extraction time of 30 minutes and 150 g kg-1 of ethanol as a modifier). solvent (se) and ultrasound-assisted solvent extraction (ue)), as natural anti-oxidants, were evaluated during 15 days st...
