A microbial biosensor based on Lactobacillus delbruecki sp. bacterial cells for simultaneous determination of lactic and pyruvic acid.

本研究旨在开发一种可同时测定乳酸和丙酮酸的微生物生物传感器。将冻干的德氏乳杆菌（Lactobacillus delbruecki sp.）细胞与聚吡咯（polypyrrole, PPy）通过电聚合法固定在铂电极表面。在含铁氰化钾的介质中，乳酸浓度依据阴极峰（+0.2 V）处安培响应差异测定，丙酮酸浓度依据阳极峰（+0.1 V）处安培...
