||Tetrazolium dye assay.
||cell hosting lambda plasmid has selective advantage over non-hosting cell. Based on a tetrazolium dye assay, the increased fitness of the lambda lysogen during aerobic growth seems to result from a continued high metabolic rate as glucose becomes limiting, whereas the metabolic rate of the nonlysogen declines.
