【摘要】 细菌耗氧能使基质资化而生成代谢物质。运用生物电池盒,设计了一种能快速检测环境污染细菌的电子测试装置。以鲜牛奶中的污染杂菌和啤酒生产发酵过程中的酵母菌为研究样品,通过向试样样品中添加适量的生物催化剂和离子激励剂进行微生物的检测。并分析研究了细菌代谢和电子发生的过程,包括各测量电极与辅酶的氧化还原反应,以及溶液中各反应物的电化学过程。实验结论表明,该方法能有效的测定牛奶中的污染微生物含量,它相对于传统活菌落检测方法相比,具有快速、简便、实时检测等优点。更多还原

【Abstract】 Hyperplasia of germs in biologic cell can consume certain amount of oxygen and thus will lay the foundation on which to metabolize and produce some substance. Using a Biologic cell, we have designed a kind of electric equipment for measurement which can quickly detect the environment-polluted germs, and take a sample of the environment-polluted germs in fresh milk and the microzyme in the process of beer produced. Adding proper amount of bio-coenzyme and ion-incentive to the germs liquor, we use the electric equipment to detect the sample in order to investigate the process of electron generation and germ’s metabolization, including the measurement of the oxidation-reduction between the pole and the coenzyme, and the electrochemistry process of every reaction matter in the liquor. The result of our study shows that the method can effectively check the germ’s number in fresh milk, and when compared to the traditional method (plate cultivating germs),it has the advantages of quickness,convenience and timeliness.更多还原
