Effects of plant extracts on sodium azide (NaN₃) mutant frequency.

Treatment	Mutant frequency and % of NaN3^#
	Preexposure*		Coexposure*
	1 mg/mL	5 mg/mL	1 mg/mL	5 mg/mL
NaN3	6.70 (100)
I	4.80 (72)^a	0.85 (13)^a	7.67 (114)	5.81 (87)
II	3.13 (47)^a	0.28 (4)^a	7.05 (105)	0.60 (9)^a
III	0.53 (8)^a	0.32 (5)^a	0.34 (5)^a	0.24 (4)^a
IV	1.53 (23)^a	0.45 (7)^a	1.77 (26)^a	0.49 (7)^a
V	0.24 (4)^a	0.34 (5)^a	1.33 (20)^a	0.77 (11)^a

#Calculated from mutant colonies (Table 4)/viable colonies. *Plant extracts were incubated with bacteria either 30 minutes before NaN₃ (preexposure) or incubated with the bacteria and NaN₃ (coexposure). ^aSignificant difference (P < 0.05) from NaN₃.
