Polygalacturonase (PG) production by Fomes sclerodermeus using solid-state fermentation (SSF) was carried out. Maximal PG activity (26 U/gdw) was obtained between days 11 and 13 at the end of exponential growth. PG activity in the crude extract was more stable at pH 5-6 and 30 degrees C and had optimum activity at pH 5 and 50 degrees C. Optimal conditions for PG extraction were: one time extrac...

This study aimed to examine the corrosion behavior of Inconel 625 in a molten salt system sodium sulfate and vanadium pentoxide at varying temperatures durations. The products, microstructure, element distribution hot extruded Na2SO4 V2O5 systems were analyzed using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS) analyses. demonstrates that allo...

So-called specific ion effects strongly impact physicochemical phenomena in among others, morphologies of polymeric membranes. This can be correlated to the identity ions, rather than just their charge or concentration. We use this effect tune properties layer-by-layer membranes prepared with polyelectrolytes polydiallyldimethylammonium chloride and polystyrene sodium sulfonate. To systematical...

In this study, the ability of Nepeta cataria L. to grow and synthesize bioactive compounds on soil treated with different salt concentrations was tested evaluate opportunity cultivating it in soils affected by salinization. N. grown containing specific amounts NaCl, Na2SO4, their mixture. After harvesting, plants were analyzed from morphological physiological point view. Salinity stress inhibit...
