Minimum inhibitory concentration (MIC) and Minimum bactericidal concentration (MBC) of DS, and extracted DS polyphenols necessary to inhibit microbial growth in vitro expressed in mg/mL.

Microorganism	DS mg/mL (SD)		DS polyphenols mg/mL (SD)
	MIC	MBC	MIC	MBC
Escherichia coli	30 (±0.83)	40 (±0.97)∗	30 (±0.11)	32 (±0.73)∗
Staphylococcus aureus	30 (±0.76)	35 (±0.54)∗	20 (±0.82)	23 (±0.94)∗

Mean and SD of results are expressed as three independent experiments in triplicates. Significant differences between each treatment and microorganism indicated as ^∗p < 0.05.
