Figure 1. Measurement of the effects of the NaOH-sodium dodecyl sulfate (SDS) lysis solution on cultured Escherichia coli.

(A) Typical BACT scattergrams of the experiment. The E. coli culture (2×10⁸ cells/mL) was mixed with an equal volume of phosphate-buffered saline (PBS) (Control) or the NaOH-SDS solution (Treated). Then, the mixture was incubated for 5 min and subjected to UF-1000i. (B) The relationship between the range of concentrations of serially diluted E. coli culture (1×10⁴ to 10⁸ cells/mL) and the NaOH-SDS solubility. Each symbol represents the average of 3 independent experiments.
