in this study, silver nanoparticles were synthesized  using the fungus, aspergillus fumigatus. the effects of three independent variables including glucose content of culture media, initial ph and initial spore concentration on biosynthesis of silver nanoparticles were investigated. these variables affect cell morphology, cell mass, size and morphology of silver nanoparticles and degree of silv...

Because of the reactivity of oxygen with biologically impor tan t compounds, e.g. unsaturated lipids, SH-conta in ing proteins and cofactors, and redox compounds (see review by Haugaard , 1968), cells in aerobic envi ronments require some mean(s) for protect ion from indiscr iminate oxidation. Since the superoxide free radical, O2, is apparently a major product of the reaction of 02 with reduce...
