The present invention relates to a method for the biocatalytic synthesis of substituted and unsubstituted phenylacetic acids and ketones from styrenes and bicyclic aromatic hydrocarbons using enzymes of microbial styrene degradation in a whole-cell sensor, as well as a kit for the biocatalytic synthesis of substituted and unsubstituted phenylacetic acids and ketones containing a whole-cell catalyst and the use of the method, wherein the method comprises the following steps:
a) providing at least one type of whole-cell catalyst, containing genes which code for the enzymes of styrene degradation and are under the functional control of a regulatable promoter, in an aqueous component,
b) activating the whole-cell catalyst with an inducer and/or an activator, leading to expression of the gene,
c) bringing the activated whole-cell catalyst into contact with a substrate,
d) isolating the reaction products produced, which are advantageously not further metabolized by the whole-cell cat and advantageously accumulate in the aqueous component.
本发明涉及一种利用微生物苯乙烯降解酶在全细胞传感器中从苯乙烯和双环芳香烃合成取代和未取代苯乙酸和酮的生物催化方法,以及包含全细胞催化剂的生物催化合成取代和未取代苯乙酸和酮的试剂盒,以及该方法的使用,其中该方法包括以下步骤:a)提供至少一种含有编码苯乙烯降解酶的基因且受可调控启动子功能控制的全细胞催化剂类型,在水相组分中,b)使用诱导剂和/或活化剂激活全细胞催化剂,导致基因表达,c)将激活的全细胞催化剂与底物接触,d)分离所产生的反应产物,这些产物优点是不会被全细胞催化剂进一步代谢,并且优点是在水相组分中积累。
