Ionizing radiation is known to penetrate food tissues, but the efficacy of the process against internalized bacteria is unknown. Leaves of Romaine lettuce and baby spinach were cut into pieces, submerged in a cocktail mixture of three isolates of Escherichia coli O157...

Allelopathy is a biological phenomenon of synthesizing and excreting compounds that can affect the growth various organisms, i.e., plant species. The aim this work was to investigate possible allelopathic influence aqueous extracts, obtained from species chia (Salvia hispanica L.), black cumin (Nigella sativa wormwood (Artemisia absinthium nettle (Urtica dioica on seed germination morphometric ...

Highly active cytochrome b6f complexes from spinach and the cyanobacterium Mastigocladus laminosus have been analyzed by liquid chromatography with electrospray ionization mass spectrometry (LCMS ). Both sizeexclusion and reverse-phase separations were used to separate protein subunits allowing measurement of their molecular masses to an accuracy exceeding 0.01% ( 3 Da at 30,000 Da). The produc...
