分离得到海洋放线菌菌株MB 97,经微生物学系统鉴定及 16SrDNA序列分析 ,定名为玫瑰黄链霉菌(StreptomycesroseoflavusMB 97)。将该菌制成生物制剂 ,在克服大豆连作障碍中应用 ,以 75kg/hm2 用量作为基肥一次施入 ,田间试验结果表明 ,在微区条件下以重茬 6年大豆为对照 ,可使大豆增产 19.4 % ;大面积示范试验 ,可使大豆增产 13.9%～ 18.3% ;经黑龙江省、湖北省两年 2 2点联网试验 ,可使大豆平均增产 15 .2 %。

Electrochemical behavior of FAD at a gold electrode studied by electrochemical quartz crystal microbalance

The electrochemical behavior of flavine adenine dinucleotide (FAD) at a gold electrode involving adsorption of the reduced form FADH(2) and desorption of the oxidized form FAD has been studied by using electrochemical quartz crystal microbalance (EQCM). EQCM can present information not only about the electrochemical behavior but also about the mass changes on the electrode surface. The electrochemical properties and frequency shifts were investigated in FAD solutions at different pH values, concentrations and scan rates. Reversible voltammograms were observed when pH<4.5 and irreversible voltammograms were found when pH greater than or equal to 4.5. It is found to be a diffusion controlled process when the concentration of FAD is lower than 2x10(-4) moll(-1) (pH 1.5). On the contrary, at concentrations higher than 2x10(-4) moll(-1) (pH 1.5), it is found to be an adsorption controlled process.
