Minimum inhibitory concentration (MIC) of caprylic acid, polygalacturonic acid, and combinations.

	MIC PG alone	MIC CAP alone	MIC PG + CAP
MRSA	0.5%	0.03%	0.25/0.01%
Ps. aerguinosa	0.75%	>0.05%	0.25/0.05%
C. albicans	>1%	>0.05%	0.25/0.01%
E. coli	1%	>0.05%	0.75/0.02%
			0.5/0.04%
S. enteridits	>1%	>0.05%	0.75/0.01%
			0.5/0.02%

MICs were determined by microbroth dilutions in accordance with CSLI (Clinical and Laboratory Standards Institute) M07 guidelines. Pathogens were exposed to a range of dilutions of PG (0, 0.25, 0.5, 0.75, and 1%), independently and in combinations (checkerboard) with a range of dilutions of CAP (0, 0.01, 0.02, 0.03, 0.04, and 0.05%). MIC was determined by visual scoring for growth (“>” denotes greater than).
