Pal, palygorskite; CM-Pal, copper-modified palygorskite. Pal and CM-Pal were added to S. typhimurium cultures. The antibacterial rate was calculated from the difference in the cell numbers at 0 h and other time. The antibacterial rate was the average value±SD. Within rows, different superscripts (a–f) indicate a significant difference (P<0.05)
