英语翻译Figure 3 shows frequency shift curves of P.aeruginosa,S.aureus,A.baumannii,E.coli,and P.maltophilia detected by proposed MSPQCmethod.This indicates that P.aeruginosa can grow well in developedacetamide broth,whereas other bacterium cannot.This method canselectively detect P.aeruginosa.Figure 2.Quantitative Detection of P.aeruginosaThe FDT,at which the frequency drops rapidly,is influenced bythe amount and growth rate of P.aeruginosa.The relationship betweenthe FDT and the logarithm of initial concentration of bacterium canbe described in Eq.(3) (He et al.1994):logC ¼ \1A \3 FDT þ B ð3Þwhere A and B are constants.The concentration of microorganism can bequantitatively detected by MSPQC.Higher concentration of bacterialsuspension results in shorter FDT.Various concentrations of P.aeruginosa detected by the MSPQC areshown in Fig.4.In the range of 10–108 cfu ml–1,the logarithm value ofinitial P.aeruginosa concentration has a linear relationship with theFDT,which can be represented by the following equation.The relativecoefficient of this regression equation is R¼\10.984.FDT ¼ 15:46 \1 0:67 logC ð4ÞThis is the basis for quantitative detection of P.aeruginosa.If the FDTis obtained,the initial number of P.aeruginosa can be calculated fromEq.(4).Figure 3.Growth curve of P.aeruginosa (curve a),S.aureus (curve b),E.coli(curve c),A.baumannii (curve d),P.maltophilia (curve e),and blank curve(curve f); all suspension concentrations were 108 cfu ml–1.64 F.He et al.Downloaded By
