A gram-negative facultative anaerobic enteric bacterium, Klebsiella pneumoniae was isolated from the hindgut of the Formosan subterranean termite (FST). It was characterized using, fatty acid methyl ester (FAME) analysis, BIOLOG assay, sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and biochemical studies. The role of this isolate seems to be nitrogen fixation because the ...

The problem of microbial growth in fuels, especially biofuels, is a very important issue. Water necessity for to occur. Unfortunately, it hard exclude all water from fuel systems during daily operations, when biodiesel added the mix. aim this work was investigate impact ionizing radiation on selected properties fatty acids methyl esters order evaluate possibility using irradiation techniques st...

Research efforts into advanced emission control systems led to significant reduction of pollutant emissions modern internal combustion engines. Sustainable renewable fuels are used further reduce their Well-to-Wheels greenhouse gas emissions. The novel aspect this paper is the compatibility investigation existing technologies for achieving low with use sustainable vehicle tests. This done on a ...

In many EU countries and outside the EU, besides the addition of pure methyl ester B-100 to diesel oil, mixtures of methyl esters are also added to fuel. To be used as fuel, methyl esters must meet certain requirements, one of which is a certain level of acylglycerols. The paper presents results of determination of acylglycerols in diesel oil dotted with fatty acid methyl esters. The compounds ...

In order to improve pyrolysis chromatographic analysis of materials that release polar functional groups e.g. carboxylic acids, a simple and rapid methylation method based on TDUpyrolysis/GC-MS in the presence of tetramethylammonium hydroxide (TMAH) was developed. Linseed oil was selected as test material because of its high triglyceride content comprising both saturated and unsaturated fatty a...

Biodiesel, known as fatty acid methyl ester (FAME), was produced from crude cottonseed oil (triglycerides) by transesterification with methanol in the presence of sodium hydroxide. This process was optimized by applying factorial design and response surface methodology (RSM) with SAS and PSIPLOT programs. A second-order mathematical model was obtained to predict the yield as a function of metha...

Methyl oleate, an example of a FAME (fatty acid methyl ester), was produced by oleic (OA) photoesterification with TiO2 and UVA light. Different parameters were evaluated optimised: catalyst pretreatment, temperature (25–65 °C), loading (1–30 % w/wOA) : alcohol molar ratio (1 3–1 55). Response surface quadratic methodology obtained central composite rotational design (RSM-CCRD) used to evaluate...

Consumers' interest in the way meat is produced is increasing in Europe. The resulting free range and organic meat products retail at a higher price, but are difficult to differentiate from their counterparts. To ascertain authenticity and prevent fraud, relevant markers need to be identified and new analytical methodology developed. The objective of this pilot study was to characterize pork be...
