Bacterial Identification by Gas Chromatographic Analysis of Fatty Acid Methyl Esters (GC-FAME)
For many years, analysis of short chain fatty acids (volatile fatty acids, VFAs) has been routinely used in identification of anaerobic bacteria. In numerous scientific papers, the fatty acids between 9 and 20 carbons in length have also been used to characterize genera and species of bacteria, especially nonfermentative Gram negative organisms. With the advent of fused silica capillary columns...
متن کاملCrystallization Behavior of Fatty Acid Methyl Esters
Biodiesel from most agricultural feedstocks has flow properties that are prone to startup and operability problems during cold weather. Biodiesel from soybean oil is generally a mixture of long-chain fatty acid alkyl esters composed of 0.15–0.20 mass fraction saturated esters (melting point [MP] 0 C) mixed with unsaturated esters (MP \ 0 C). This work investigates the crystallization properties...
متن کاملComparative Analysis of Eight Esterification Methods in the Quantitative Determination of Vegetable Oil Fatty Acid Methyl Esters (FAME)
Foram comparados os resultados de determinações quantitativas de ésteres metilícos de ácidos graxos de óleos vegetais (soja, linhaça e dendê) entre oito métodos de esterificação com catálises ácidas e básicas. Os métodos selecionados foram descritos por Metcalfe, 1966 (MET, ref. 17); Bannon, 1982 (BAN, ref. 18); Joseph e Ackman, 1992 (JAC, ref. 3); Hartman e Lago, 1973 (HLA, ref. 19); Jham, 198...
متن کاملGC/MS Analysis of Trace Fatty Acid Methyl Esters (FAME) in Jet Fuel Using Energy Institute Method IP585 Author
This paper describes the application of IP Method 585 for measuring trace amounts of FAME in jet fuel using the Agilent 5975C GC/MS system. This method uses selective ion monitoring (SIM) to improve FAME selectivity and sensitivity in the complex jet fuel sample matrix. This was demonstrated by running jet fuel samples spiked with known quantities of soybean biodiesel FAMEs. Full recovery of th...
متن کاملPreparation of fatty acid methyl esters for gas-liquid chromatography.
A convenient method using commercial aqueous concentrated HCl (conc. HCl; 35%, w/w) as an acid catalyst was developed for preparation of fatty acid methyl esters (FAMEs) from sterol esters, triacylglycerols, phospholipids, and FFAs for gas-liquid chromatography (GC). An 8% (w/v) solution of HCl in methanol/water (85:15, v/v) was prepared by diluting 9.7 ml of conc. HCl with 41.5 ml of methanol....
