项目摘要

Application of a bisphenol A(BPA)-degrading bacterial strain to regenerate thermographic papers was proposed. BPA contained in such troublesome papers make strongly-colored compounds in the renewal processes by the reaction with redox dyes which are also contrained in the papers, and thereby spoils the renewal of papers. If we can utilize BPA-degrading bacteria for removing BPA.above-mentioned problem may be overcome. An isolated bacterial strain Pseudomonas paucimobilis FJ-4 could completely and efficiently degrade BPA via its cleavage at the propane-part. Production of the catabolic enzymes was highly inducible and the optimal pH and temperature of FJ-4 for BPA degradation were 7.0-7.2 and ca.30゚C,respectively. FJ-4 showed the capability of degrading BPA contained in a thermographic paper pulp, which consequently lead to the decolorization of the colored matter made from a redox dye catalyzed by BPA.The decolorization was not affected at all by the presence of chemicals such as CaCO_3, NaOH,AL_2(SO_4)_3 which are used in existing paper renewal processes. These results suggested that renewal processes of renewal of themographic paper using BPA-degrading bacteria is possible.
提出了一种双酚a (BPA)降解菌株在热像纸再生中的应用。这些麻烦的纸张中含有的双酚a在更新过程中与纸张中含有的氧化还原染料发生反应,产生强烈的颜色化合物,从而破坏了纸张的更新。如果我们能利用双酚a降解细菌去除双酚a。上述问题是可以克服的。一株分离的少动假单胞菌FJ-4可以通过其在丙烷部分的裂解完全有效地降解BPA。FJ-4降解BPA的最佳pH和温度分别为7.0 ~ 7.2和ca.30ºC。FJ-4表现出降解热印纸浆中BPA的能力,从而导致由BPA催化氧化还原染料制成的有色物质脱色。现有纸张更新工艺中使用的CaCO_3、NaOH、AL_2(SO_4)_3等化学物质对脱色效果没有影响。这些结果表明,利用双酚a降解菌对热像纸进行更新是可行的。
