Summary of contact angles (degrees) with aqueous, low- and high-ionic-strength solutions for lactobacillus strains with and without SLP^a

Lactobacillus strain	SLP	Contact angle (°)
		10 mM KCl	100 mM KCl
L. acidophilus ATCC 4356	Yes	76 ± 4	47 ± 3
L. crispatus JCM 5810	Yes	66 ± 9	70 ± 13
L. casei ATCC 393	No	32 ± 5	65 ± 5
L. casei 393*/CA5A′	Yes	45 ± 7	50 ± 7
L. gasseri LMG9203	No	45 ± 3	70 ± 9
L. johnsonii LMG9436T	No	42 ± 6	47 ± 4

^aContact angles represent mean values of 10 measurements, equally distributed over two bacterial lawns, prepared out of different bacterial cultures.
