Abstract: The positive mutagenic response to six chemicals and doubtable positive mutagenic response to two chemicals and negative mutagenic response to two chemicals were demonst rated by a spontaneous dark mutant (kmutant) , St rain T9171 , isolated from photobacterium phosphoreum T3 Spp. Mutagenic mutant has higher sensitivity to genotoxic chemicals as compared with conventional Ames test . It is possible to become a simple sensitive short-term bioloical test method for the detection to mutagenic compounds in environment .

Key words: Photo 　bacteria, Dark mutant
