Values are mean±SD.
The values in parentheses are the inhibition rates (%).
Spontaneous means the revertants naturally formed without AFB1 and methanol extracts of ganjang.
Control means the revertants induced by AFB1 without methanol extracts of ganjang.
OWOG, onggi without glaze.
OWG, onggi with glaze.
CRM, ceramics.
STL, stainless.
GLA, glass.
Means with the different letters in the same column are significantly different (p<0.05) by Duncan’s multiple range test.
