A. Experimental protocol. Bacterial survival was monitored for mixed or single bacteria on other surfaces (aluminum, plastic, stainless steel) at distinct temperature (15°C, 30°C, 37°C) for 11 days by a CFU assay (CFU). Ec, E. coli (ATCC 25922). Sa, S. aureus (ATCC 29213). B. Bacterial numbers immediately (within 20 min) after drying. Ec, E. coli (ATCC 25922). Sa, S. aureus (ATCC 29213). C. Changes in bacterial numbers at distinct temperatures (15°C, 30°C, 37°C) over 11 days, as determined by a CFU assay. Ec, E. coli (ATCC 25922). Sa, S. aureus (ATCC 29213). *, p<0.05 vs. the values at room temperature. **, p<0.05 vs. 30°C.
