“…N 2 , N 2 O, N 2 O -, NH 4 + ), ammonium has the highest economic value. It has an important potential as fertilizers [42][43][44] and as nitrogen source for microorganism cultures producing biohydrogen [45][46][47]. The use of cheap inorganic nitrogen source appears relevant from an economical point of view, contrarily to organic nitrogen sources which are often more expensive [48].…”

“…Then the extraction buffer (pH 8.2) containing 0.2 mol Tris-HCl, 1 mmol EDTA, 5 mmol FAD and 2 mmol ß-mercaptoethanol per liter, plus 0.025% (w/v) casein milk powder was added and quickly mixed in the mortar while in frozen state. The insoluble arenaceous quartz and extraction medium were added at a rate of 1.5 g and 15 mL*g -1 fresh weight, respectively [6] . The tissue was suspended through additional grinding as the mixture thawed, using the shearing action of ice crystals to aid in grinding.…”

“…(11,12) Nitrate reductase (NR) is the first enzyme involved in nitrate assimilation in higher plants. (13) The enzyme catalyzes the rate-limiting and regulated step, the two-electron reduction of NO 3 -to NO 2 -, in the pathway of inorganic nitrogen assimilation. (14) The enzyme has been isolated from a variety of sources including algae, fungi, yeast, and higher plants (15,16) and, in all cases, has been shown to consist of multimeric proteins composed of identical subunits, each of which contains three cofactors, flavin adenine dinucleotide (FAD), a b-type cytochrome (cytochrome b557), and molybdenum cofactor prosthetic groups in a 1:1:1 stoichiometry per subunit.…”
