TABLE 1.

Antibacterial activity of lacidophilin.

Groups	OD₆₀₀ (37°C 72 h fermentation)	Inhibition zone diameter (against E. coli)	Inhibition zone diameter (against S. aureus)
Negative control	0.001 ± 0.001^b	0 ± 0^c	0 ± 0^c
Positive control	2.268 ± 0.189^a	16.593 ± 0.668^b	15.257 ± 0.386^b
The treated group	2.350 ± 0.063^a	19.830 ± 0.960^a	18.460 ± 0.685^a

Values are represented as mean ± SD from triplicate experiments. Different lowercase superscripts in the same column indicate that the antibacterial effect is significantly different (P < 0.05). The diameter of the inhibition zone around the Oxford cup is used to denote the antibacterial activity of lacidophilin.
