(a) Effect of different pH values on the production and killing activity of killer toxin produced by D. hansenii against pathogenic bacteria and yeasts. (b) Inhibition zone distributed within wells filled with partially purified concentrated killer toxin after 48 h at 37°C. S. aureus was used as sensitive bacteria. (c) C. albicans was used as sensitive yeast. Values in the same column followed by the same letter are not statistically different by Duncan's multiple range test at (p < 0.05).
