Stability of Bacteriocin-Like Inhibitory Substance (BLIS) Produced by Pediococcus acidilactici kp10 at Different Extreme Conditions

Table 4

The activity of crude BLIS after exposure to different temperatures with different indicator microorganisms (L. monocytogenes ATCC 15313, E. coli ATCC 35218, and S. aureus ATCC 33591).

Temperature	BLIS Activity in AU/mL
	L. monocytogenes; ATCC 15313	E. coli ATCC; 35218	S. aureus; ATCC 33591
Control (crude BLIS)	4689.42	189.21	52.39
4°C (24 h)	4689.42	189.21	52.39
- 20°C (24 h)	2327.75	64.27	35.85
- 80°C (24 h)	2327.75	64.27	35.85
100°C (15 mins)	4689.42	154.25	ND
121°C (15 mins)	ND	ND	ND

ND=nondetectable.
Means values in the same row expressed with different superscript letters are significantly different at P< 0.05.
