The analysis of the non-volatile components of heated fatty acid esterified propoxylated glycerols
… of the oils showed increases in % polymer, free fatty acids, total acids, total aldehydes, food oil sensor readings, and red and yellow color during heating, while peroxides decreased. Heated oils, with antioxidants, were fractionated with supercritical carbon dioxide into relatively pure …

Investigations of the Tribological Effects of Engine Oil Dilution by Vegetable and Animal Fat Feedstock Biodiesel on Selected Surfaces
… and animal fat feedstocks. Therefore, the fatty acid methyl ester components of biodiesel may vary upon these sources of feedstock. In this thesis work, engine oil is diluted with vegetable (canola oil, peanut oil and soybean oil biodiesel) and animal (chicken fat) feedstock biodiesels at …

Novel supercritical biodiesel plant design & process scale-up
… separation systems (ASS) to separate Free Fatty Acid Methyl Ester (FAME)/Biodiesel (BD), glycerol and methanol.</p> <p>We investigated E. Coli to digest glycerol and make ethanol at anaerobic conditions. We have designed various primers that make this DNA. We developed a scaled-up plant …

Improvements to the biodiesel process
Biodiesel (fatty acid methyl ester, FAME) is a renewable diesel fuel made from vegetable oil and methanol. The two main problems with the process are disposal of waste streams and product purity. This thesis studies biodiesel process improvements, especially glycerol conversion to hydrogen and …

A preliminary analysis of the lipid contents of a biofilm from a Yellowstone hydrothermal pool
… allowed for the identification of decanoic acid methyl ester, a fatty acid methyl ester. From the column chromatography, only the saturated hydrocarbon fraction yielded interesting compounds; these were a series of n-alkanes (n-C₁₇, n-C₂₀, and n-C₂₃ - n-C₃₁), two branched alkanes …

The effect of waste cooking oil methanol molar ratio on yield and properties of biodiesel produced in a mini plant
… from WCO are difficult and costly when free fatty acid content more is than 2%. There are some problems of WCO such that it can lead to pollution and health risk. Therefore, this research were carried out to propose a simple small pilot plant to produce biodiesel using WCO and to investigate …

Synthesis and evaluation of polyol based biolubricants from vegetable oils
… point while the content of polyunsaturated fatty acids (PUFA) was negatively correlated with oxidative stability. Brassica rapa cultivars, with less than 3.5% saturated fat and less than 20% polyunsaturated fat, can be an excellent feedstock with improved cold fluidity and oxidative …

Studies of the nature of Burkholderia cepacia in cystic fibrosis
… metabolic capabilities, antibiotic sensitivity, fatty acid methyl ester (FAME) profiles restriction digest analysis of chromosomal DNA by pulsed-gel electrophoresis (PFGE) (with the use of two separate restriction enzymes) and outer membrane protein (OMP) profiles. This revealed isolates of the …

Hydrothermal liquefaction of microalgae: Influence of varying cell compositions on biocrude yield and quality
… yield is strongly determined by the increasing fatty acid methyl ester (FAMEs) content and not gross lipid content as previously thought. A model linking biomass composition to HTL biocrude yield is proposed based on the contributions from a baseline (non-FAMEs) fraction and FAMEs fraction of …

Phenotypic and genetic diversity of pseudomonads associated with the roots of field-grown canola
… sequences and selected phenotypic properties (fatty acid methyl ester (FAME) profiles, antibiotic resistance, extracellular enzyme production and carbon substrate utilization). On the basis of 16S rRNA and cpn60 gene sequences, two major clusters were observed, the Pseudomonas fluorescens …

Monitoring of Biodiesel Transesterification Process Using Impedance Measurement
… been the subject of extensive investigation. Fatty acid methyl ester (FAME) based Biodiesel manufactured from vegetable oils or animal fats is an excellent candidate to replace common diesel fuel being renewable, non-toxic and often giving rise to reduced exhaust gas emissions. The …

Metabolism of omega-3 fatty acids in carriers of apolipoprotein E epsilon 4
… have found that consuming a diet rich in omega-3 fatty acids such as docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) can decrease the risk of developing Alzheimer’s disease. However, the benefit of consuming omega-3 fatty acids is not seen in APOE4 carriers. Additionally, studies have …

Synthesis of environmentally-friendly polyurethane dispersions based on soybean oil- derived polyols and their applications in advanced water-based and uv-cure coatings
… soy-polyol was developed from epoxidized soy fatty acid methyl ester (ESFAME). The cationic ring opening of oxirane oxygen groups from ESFAME resulted in polyol with average hydroxyl number 88 mgKOH/g and number average molecular weight 1517.</p> <p>The indigenous soy-polyol was used as soft …
