Aerobic thermotolerant methane oxidizers utilize as a sole carbon and energy source, predominantly they are associated with the phylum Proteobacteria. Here we present two further new strains (HGS-45: coccusshaped HGF-47: rod-shaped vibrioid) of obligate proteobacterial methanotrophic bacteria, which were isolated from an abandoned tropical natural gas field wet soil sample in northeast Banglade...

dispersive liquid-liquid microextraction method (dllme) combined with high-performance liquid chromatography-ultraviolet detection (hplc-uv) was used to determine thiamine (b1), nicotinamide (b3) and pyridoxine (b6) in sour cherry juice. this method was rapid, simple and sensitive. separation was accomplished using a c18 column. the optimum chromatographic conditions were found to be: mobile ph...

in this study, we combined ionic liquid-based dispersive liquid liquid micro extraction (il-dllme) with faas for determining the palladium in different real samples at the trace level. 1-hexyl-3-methylimidazolium hexafluorophosphate [hmim][pf6] ionic liquid and 1-(2-pyridylazo) 2-naphthol (pan), were chosen as the extraction solvent and the chelating agent, respectively. the hydrophobic pd–pan ...
