Bw. Chang et al., An improving method for determination of Escherichia coli population basedon multi-channel series piezoelectric quartz crystal system, SENS ACTU-B, 65(1-3), 2000, pp. 105-107
A new application of conductometry based on multi-channel series piezoelect
ric quartz crystal (MSPQC) is described for quantification of the bacteria
population and the antibiotic effect. The result of MSPQC system showed a g
ood linear relation (r = -0.9885) between the frequency detection time (FDT
) and its initial concentration of Escherichia coli, and the antibiotic tha
t effected on the metabolism activity of E. coli had a significant variatio
n of slope as a quantification index. (C) 2000 Elsevier Science S.A. All ri
