将电阻抗法应用于细菌种类鉴别试验。笔者用自制的微生物传感器和电阻抗测量装置等,在一定条件下,利用微生物在生长繁殖过程可使培养基的电阻抗值减低的现象,通过测量接种细菌的培养基电阻抗值,并将细菌在培养期间内取得的所有电阻抗值数据描记成“阻抗曲线图谱”。试验证实,不同种类细菌所形成的阻抗曲线图谱是不相同的,是该种细菌所特有的。我们可以根据这些 “阻抗曲线图谱”的形态差异进行细菌种类鉴别,试验研究取得了预期的结果。 The electrical impedance method used in bacterial species identification test. Using self-made microbial sensors and electrical impedance measurement devices, under certain conditions, the use of microorganisms in the process of growth and reproduction can reduce the electrical impedance of the medium by measuring the bacterial resistance of the medium inoculated with electricity, and bacteria All electrical impedance data taken during the incubation period are described as “impedance profile.” Experiments confirmed that different types of bacteria formed by the impedance curve is not the same, is unique to the bacteria. We can identify bacterial species based on the morphological differences of these “impedance profiles” and the experimental results have achieved the expected results.
