  1. For laser diffraction, Pickering emulsions which showed physical stability index of 100% after 4 days were only analyzed. For apparent viscosity and zeta potential analyses, Pickering emulsions which remained stable after 1 day were only analyzed.
  2. ND not determined; MC microorganism concentration (%); Different lowercase and uppercase letters indicate significant differences (p < 0.05) among different microorganisms at the same concentration of 10 wt% and 15 wt%, respectively. For a same microorganism, the asterisk (*) shows significant differences (p < 0.05) between different concentrations (10 wt% and 15 wt%).
