Effect of bile salts (concentration 0.1 to 0.6) on L. plantarum (BLp) bacteriocin activity against Gram-negative bacteria.

	Gram-negative bacterial strains	Zone of inhibition (mm) vs. bile salt (solution variations in %)					Pearson's correlation b/w solution variations and activity (P value = 0.05 (two-tailed))	R squared (r2)
		0.1%	0.2%	0.3%	0.4%	0.6%
BLp bacteriocin	K. pneumoniae	10.10	8.66	10.30	7.30	6.23	P = 0.074956 (not significant)	0.7063
	P. aeruginosa	15.46	12.76	14.30	7.63	4.23	P = 0.020608 (significant)	0.8707
	E. coli	29.86	10.16	20.66	8.16	7.50	P = 0.164037 (not significant)	0.5295
	A. baumannii	5.43	3.66	4.43	2.80	1.80	P = 0.027335 (significant)	0.8446
	S. paratyphi	25.16	15.50	23.5	7.36	6.36	P = 0.092823 (not significant)	0.6646
