Experiments were designed to evaluate the corrosion-related consequences of storing/transporting fatty acid methyl ester (FAME) alternative diesel fuel in contact with natural seawater. Coastal Key West, FL (KW), and Persian Gulf (PG) seawaters, representing an oligotrophic and a more organic- and inorganic mineral-rich environment, respectively, were used in 60 day incubations with unprotected...

In recent years, biodegradable and alternative biodiesel has attracted increased attention worldwide. Producing biodiesel from biomass involves critical separation and purification technology. Conventional technologies such as gravitational settling, decantation, filtration, water washing, acid washing, organic solvent washing and absorbent applications are inefficient, less cost effective and ...

The bacterial pathogens Erwinia carotovora subsp. atroseptica, E. carotovora subsp. carotovora and E. chrysanthemi are responsible for soft rot diseases, affecting plants in the field and/or in storage. Thirty-one strains from Portugal and elsewhere were characterised by classical, fatty acid methyl ester (FAME) and molecular methods (MSP-PCR and BOX-PCR). Ten strains were identified as E. caro...

Burkholderia (Pseudomonas) cepacia is a common environmental bacterium which can be pathogenic for plants and humans. In this study, four strategies were used to identify aquatic isolates: API test strips, hybridization with species-specific DNA probes for the 16S and 23S rRNA genes, fatty acid methyl ester (FAME) profiles, and growth on selective medium (TB-T agar [C. Hagedorn, W. D. Gould, T....

Automating fatty acid derivatization and preparation of calibration standards on an Agilent 7696A Sample Prep WorkBench for fatty acid methyl esters (FAME) analysis can provide comparable precision, better recoveries, and more accurate calibration compared to manual procedures. Hands-on time, reagent usage, and exposure to hazardous chemicals are all greatly reduced. This automated approach has...

The aim of this study was to evaluate the impact of catechol and phenol added to culture media separately and with glucose as an additional, easily-degradable carbon source on fatty acid methyl ester (FAME) composition in Pseudomonas vesicularis. Simultaneously, the degradation rates of aromatic substrates used were investigated in single and binary substrate systems. Both catechol and phenol t...

The aim of this work was the study and evaluation winery by-products in framework circular bioeconomy. Grape seeds grape skins from Greek Ionian Islands varieties were analyzed an attempt to provide appropriate basis for model development their sustainable exploitation at a local or regional level. collected directly wineries immediately after vinification process by chromatographic spectroscop...

Both the continuous and batch transesterification of linseed oil were examined in order to maximize the fatty acid methyl esters (FAME) yield. The continuous process was conducted in a packed bed reactor using calcium oxide as a heterogeneous catalyst. In addition, the impact of two variables, namely the molar ratio of methanol to oil and the flow rate (ml/min), on the FAME yield were stu...

Anaerobic manure storage systems are one of the major contributors to the odor and environmental pollution associated with swine (Sus scrofa) production systems. The microbial ecology of manure storage systems and the relationships between microbial communities and odor production are largely unknown. In this study, we used community fatty acid methyl ester (FAME) analysis to generate lipid pro...
