Fig. 1From: Shaping the subway microbiome through probiotic-based sanitation during the COVID-19 emergency: a pre–post case–control studyTests of PCHS-Bacillus and disinfectant compatibility. PCHS-Bacillus viability in the presence of the indicated disinfectants was assessed in vitro on hard nonporous surfaces. a PCHS-Bacillus spores spread on surfaces and subsequently treated with the indicated disinfectants. b PCHS-Bacillus spores spread on surfaces previously treated with the indicated disinfectants. c PCHS-Bacillus growing bacteria seeded on surfaces previously treated with the indicated disinfectants. All results are expressed as mean CFU ± S.D. of duplicate samples in two independent experiments, measured after 24 h incubation on TSA platesBack to article page
