Genotoxicity Assessment of Multispecies Probiotics Using Reverse Mutation, Mammalian Chromosomal Aberration, and Rodent Micronucleus Tests

Table 2

Genotyping of the test bacterial strains.

Strains	Histidine requirement	ΔuvrB mutation	rfa mutation	Ampicillin resistance
TA97	+	+	+	+
TA98	+	+	+	+
TA100	+	+	+	+
TA102	+	Θ	+	+
TA1535	+	+	+	Θ

+: the strain carries the mutation; Θ: the strain does not possess the feature.
