The present invention disclosed is a method for screening metabolites essential for the growth of microorganism using metabolic flux analysis. More specifically, the present invention relates to the method for screening metabolites essential for the growth of microorganism, by selecting a target microorganism, constructing a metabolic network model of the selected microorganism, inactivating the consumption reaction of each of metabolites in the constructed metabolic network model, analyzing the metabolic flux of the metabolites to select metabolites essential for the growth of the microorganism, and confirming the selected metabolites using the utilization of each of the metabolites, defined as flux sum (Φ ). According to the present invention, metabolites essential for the growth of microorganism, and genes involved in the essential metabolites, can be screened in a convenient manner, and drug-target genes against pathogenic microorganisms can be predicted by deleting genes associated with the metabolites screened according to the method. |
