Grable and Siemer (1968) presented a relationship between redox potential
(Eh) and oxygen concentration (%).
Investigating mitochondrial redox potential
with redox-sensitive green fluorescent protein indicators.
Mean redox potential
of potting medium for flooded plants varied from + 67 mV to -297 mV for mahogany and from + 189 mV to - 260 mV for pond apple indicating that hy poxic conditions existed in the root zones of flooded plants within 2 d after flooding in both experiments.
2+] which simultaneously reduces the redox potential
Other reason for biological acceleration of galvanic interaction was the chelation of cysteine secreted by Tf with pyrite, which altered the redox potential
of Fe2+:Fe3 couple, thus accelerating the oxidation of pyrite sulfides as + indicated by Rojas and Tributsch, (2001).
Samplings were done twice per month from April to August: redox potential
(Eh, in mVolt) is a chemical indicator for the quality of superficial layer of sediment.
A correlation has been observed between the redox potential
and anticancer activity for Cu chelates of elesclomol and its analogs, suggesting that the ability to promote redox cycling of Cu(II) to Cu(I) is necessary for anticancer activity.
(Eh) was determined in the wet soils at 0, 7, 14, and 21 days after imposition of treatments and during recovery periods.
To provide an indication of soil oxygen content, soil redox potential
was measured with a metallic combination electrode (Accumet Model 13-620115, Fisher Scientific, Pittsburgh, PA) attached to a portable volt/pH meter (Accumet model AP62, Fisher Scientific, Pittsburgh, PA).
Whole fresh and dried fruits were assessed for phenolics, ascorbic acid, antioxidant activity and redox potential
did not exhibit any discernable pattern; it was generally high, ranging from 200--400 mV.
The lowest pH and redox potential
under submerged conditions were observed for the clay soils but pH and redox potential
were not limiting to the growth of rice for any soil (Table 2).
