armoracia rusticana/superoxide dismutase

Peroxidase associated with isolated horseradish cell walls catalyzes the formation of H2O2 in the presence of NADH. The reaction is stimulated by various monophenols, especially of coniferyl alcohol. NADH can be provided by a bound malate dehydrogenase. This system is capable of polymerizing

Isolated cell-wall suspensions from horseradish in the presence of 5×10(-4) M MnCl2 catalyze the production of hydrogen peroxide at the expense of either NADPH or NADH. This reaction is inhibited by scavengers of the superoxide free radical ion such as ascorbate or dihydroxyphenols or by superoxide

Bioproducts production using monomeric sugars derived from lignocellulosic biomass presents several challenges, such as to require a physicochemical pretreatment to improve its conversion yields. Hydrothermal lignocellulose pretreatment has several advantages and results in solid and liquid streams.
