F420H2:NADP oxidoreductase is found in methanogenic, sulfate-reducing and halophilic archaea and also in some bacteria. The putative gene encoding the enzyme was cloned from Methanobacterium thermoautotrophicum (strain Marburg) and heterologously expressed in Escherichia coli. The overproduced active enzyme was purified, characterized and crystallized.
A multiresidue method for the analysis of 35 common contaminants (including pesticides, polycyclic aromatic hydrocarbons and phenols) in lough and river waters from Castilla y León Spanish region, by using supercritical fluid chromatography (SFC) with five silica packed columns, is described. In order to decrease the detection limits, a preconcentration step by coupling solid-phase extraction to the SFC system was used. The different variables affecting the extraction procedure were studied and optimized, selecting the Isolute Env+ as the best sorbent. The detection limits achieved ranged from 0.4 to 2.6 micrograms l-1.
