Notes:
Ionophores (carbonyl cyanide m-chlorophenylhydrazone; valinomycin; and the hopderived compounds colupulone, trans-isohumulone and trans-humulinic acid) reduced the rate of dodecanal-dependent light emission from luxA/B-transformed cells of Lactococcus lactis subsp. diacetylactis F712 when the cells were suspended in a buffered medium (pH 6.4) containing glucose. This allowed an assay for ionophores to be devised and permitted measurement of the effects of such compounds on the test organism by the use of a non-destructive technique in real time.
