The data obtained are consistent with hydrogen atom abstraction by the tert-butylperoxy radical followed by radical combination

  • Removal of<i>p</i>-Alkylphenols from Aqueous Solutions by Combined Use of Mushroom Tyrosinase and Chitosan Beads
    作者:Kazunori YAMADA、Tomoaki INOUE、Yuji AKIBA、Ayumi KASHIWADA、Kiyomi MATSUDA、Mitsuo HIRATA

    Enzymatic removal of p-alkylphenols from aqueous solutions was investigated through the two-step approach, the quinone conversion of p-alkylphenols with mushroom tyrosinase (EC 1.14.18.1) and the subsequent adsorption of quinone derivatives enzymatically generated on chitosan beads at pH 7.0 and 45 °C as the optimum conditions. This technique is quite effective for removal of various p-alkylphenols from an aqueous solution. The % removal values of 97–100% were obtained for p-n-alkylphenols with carbon chain lengths of 5 to 9. In addition, removal of other p-alkylphenols was enhanced by increasing either the tyrosinase concentration or the amount of added chitosan beads, and their % removal values reached >93 except for 4-tert-pentylphenol. This technique was also applicable to remove 4-n-octylphenol (4NOP) and 4-n-nonylphenol (4NNP) as suspected endocrine disrupting chemicals. The reaction of quinone derivatives enzymatically generated with the chitosan’s amino groups was confirmed by the appearance of peaks for UV–visible spectrum measurements of the chitosan films incubated in the p-alkylphenol and tyrosinase mixture solutions. In addition, 4-tert-pentylphenol underwent tyrosinase-catalyzed oxidation in the presence of hydrogen peroxide.
    在 pH 值为 7.0 和 45 °C 的最佳条件下,研究人员通过两步法研究了酶法去除水溶液中的对烷基酚:用蘑菇酪氨酸酶(EC 1.14.18.1)转化对烷基酚的醌,然后将酶法生成的醌衍生物吸附在壳聚糖珠上。这种技术对去除水溶液中的各种对烷基酚非常有效。碳链长度为 5 至 9 的对正烷基酚的去除率为 97%-100%。此外,通过提高酪氨酸酶浓度或增加壳聚糖珠的添加量,也可提高对其他对烷基酚的去除率,除 4-叔戊基苯酚外,其他对烷基酚的去除率均大于 93%。该技术还适用于去除疑似干扰内分泌的化学物质 4-正辛基苯酚(4NOP)和 4-正壬基苯酚(4NNP)。在对烷基酚和酪氨酸酶混合物溶液中培养的壳聚糖薄膜的紫外可见光谱测量中出现了峰值,这证实了酶生成的醌衍生物与壳聚糖的氨基发生了反应。此外,4-叔戊基苯酚在过氧化氢的存在下发生了酪氨酸酶催化的氧化反应。

    公开号:US20110059215A1
    公开(公告)日:2011-03-10
    Disclosed is a method for cheaply and easily producing theaflavins. After adding a large quantity of water to raw tea leaves that have not undergone wilt treatment, the tea leaves are crushed in a blender and then let stand, shaken, or agitated, thereby efficiently convening four types of catechins in the raw tea leaves to theaflavins. After adding water and crushing the raw tea leaves, letting the tea leaves stand allows theaflavins to be selectively obtained with high yield. Shaking the raw tea leaves which have had water added and been crushed allows four types of theaflavins to be obtained with high yield. The generated theaflavins can be easily collected using a method such as extraction by organic solvent.
