The impact of different concentrations of three amino acids (cysteine, histidine and methionine) which are part of the amino acid sequence of rusticyanin on dissolution of pyrite is investigated by the application of electrochemical techniques. Cyclic voltammetric studies conducted in the anodic direction from corrosion potential have shown that in the vicinity of corrosion potential, histidine and methionine do not influence dissolution of pyrite independently on their concentrations. On the other hand, cysteine and solutions of these amino acids in the molar ratios Cys:His:Met/1:1:1 and Cys:His:Met/1:2:1 accelerate dissolution at concentrations 10⁻² mol L⁻¹ and 10⁻³ mol L⁻¹. Potentiodynamic polarization measurements showed that methionine does not affect the anodic and cathodic dissolution at all concentrations, while histidine does not affect significantly on the anodic dissolution at all concentrations. Cysteine and solutions of three amino acids in the molar ratio Cys:His:Met/1:1:1 and Cys:His:Met/1:2:1 cause intensive cathodic inhibition and anodic activation at concentrations 10⁻² mol L⁻¹ and 10⁻³ mol L⁻¹ respectively.

通过应用电化学技术研究了不同浓度的三种氨基酸（半胱氨酸，组氨酸和蛋氨酸）（它们是质朴霉素的氨基酸序列的一部分）对黄铁矿溶解的影响。从腐蚀电位沿阳极方向进行的循环伏安研究表明，在腐蚀电位附近，组氨酸和蛋氨酸不会独立于其浓度而影响黄铁矿的溶解。另一方面，半胱氨酸和这些氨基酸以Cys：His：Met / 1：1：1和Cys：His：Met / 1：2：1摩尔比的溶液在10 ^-2  mol L ^-1的浓度下加速溶解和10 ^-3  mol L ^-1。电位动力学极化测量表明，蛋氨酸在所有浓度下均不影响阳极和阴极溶解，而组氨酸在所有浓度下均不显着影响阳极溶解。半胱氨酸和三种氨基酸摩尔比为Cys：His：Met / 1：1：1和Cys：His：Met / 1：2：1的溶液在浓度为10 ^-2  mol L ^-1时引起强烈的阴极抑制和阳极活化作用和10 ^-3  mol L ^-1。
