Table 1. Biological activity of GS granules.

Sample	MIC (μg/ml) for bacteria					HC90 (μg/ml) for haematocrit
	E. coli	P. aeruginosa	S. aureus	E. faecalis	S. mutans	0.25%	2.5%
GS solution	16	32	4	8	2	12 ± 3	28 ± 4
GS granules	16	64	4	8	2	38 ± 2	676 ± 48

MIC was performed with three biological replicates in at least two independent experiments. HC₉₀ data are means of three independent experiments ± s.d.
