Effects of detergents on H8 activity.

Detergent	Relative activity (%)
	0.001% (v/v)	0.01% (v/v)	0.1% (v/v)
Tween 20	128.9 ± 5.6	112.3 ± 4.9	110.6 ± 3.4
Tween 80	102.9 ± 3.4	103.8 ± 3.0	112.3 ± 2.7
Triton X-100	113.4 ± 1.8	84.2 ± 0.5	62.8 ± 3.0
SDSa	33.0 ± 0.6	1.4 ± 0.2	LDb

^aThe concentrations of SDS used were presented in w/v.

^bLD indicates that the value was less than the limit of detection.
