Antibacterial and antifungal activity of horse oil, hydrolysed horse oil and sophorolipids measured by inhibition of bacterial or fungal cell growth. The antibacterial capacity of 0.5% horse oil, hydrolysed horse oil or sophorolipids against E. coli, P. aeruginosa and S. aureus was examined and compared with that of the 30% butylene glycol (BG) positive control (A). The antifungal capacity of different concentrations of sophorolipids against C. albicans and A. niger was also examined and compared with that of the 30% BG positive control (B). Data are presented as the mean ± SD from three separate experiments respectively. **P < 0.01 vs. BG group; ***P < 0.001 vs. BG group.
