生物催化2-氰基吡嗪生产吡嗪酰胺的方法及其菌株
摘要：
本发明提供了一种生物催化生产2－氰基吡嗪生产吡嗪酰胺的方法，及其制备过程中所用到的一株新菌株——粘质沙雷氏菌(Serratia marcescens)ZJB－09104。所述方法包括：在以2－氰基吡嗪为底物、以粘质沙雷氏菌(Serratia marcescens)培养获得的腈水合酶为催化剂的反应体系中，于pH6.0～8.0、20～40℃下进行催化水合反应，制得所述吡嗪酰胺。本发明将粘质沙雷氏菌菌株ZJB－09104用于生物催化生产吡嗪酰胺实验，结果表明，该菌可有效生物催化生产吡嗪酰胺，12h内2－氰基吡嗪转化率达到83.8％，因此该菌在生物催化生产吡嗪酰胺的领域中具有广泛的应用前景。
摘要（英）：

The invention provides a method of producing 2-cyanopyrazine by biocatalysis to produce pyrazinamide and a new strain, Serratia marcescens ZJB-09104, which is used in the preparation process. In the method, the pyrazinamide is obtained through the catalytic hydration reaction under the conditions that the pH is 6.0-8.0 and the temperature is 20-40 DEG C in a reaction system which uses 2-cyanopyrazine as a substrate and nitrile hydratase which is obtained by the culturing of the Serratia marcescens as a catalyst. The method applies the Serratia marcescens ZJB-09104 to the experiments producing pyrazinamide by biocatalysis. Results show that the strain has a wide application prospect in the field of producing pyrazinamide by biocatalysis as the strain can effectively produce the pyrazinamide by biocatalysis and the transformation ratio of the 2-cyanopyrazine.attains 83.8 percent within 12h.
