Microbicidal efficacy of test samples against contaminated suspension. The CFU/mL for total viable bacterial cells (TC) and coliform bacteria (CF) following treatment for 15 min with undiluted and two-fold diluted BiSCaO Water and 0.4 and 0.2 wt.% of BiSCaO suspension, dispersion, and colloidal dispersion could completely sterilize (<10 CFU/mL), while about 10,000 CFU/mL of both TC and CF with 12h-stirred BiSCaO Water remained viable even with the no diluted test sample. Plating and counting were performed as a set of four technical replicates (n = 4) and error bars represent means ± S.D. ND denotes not detected.
