The invention provides a method for detecting the relative content of phenylalanine in cyanobacteria cells in real time by using codon degeneracy, and belongs to the technical field of gene modification. The degeneracy of phenylalanine codons in synechocystis is utilized, the proportion of preference corresponding to phenylalanine in chloramphenicol resistance genes and rare codons in chloramphenicol resistance genes is modified by a genetic engineering modification method, and the expression efficiency of antibiotic genes is controlled. According to the method, a direct relation among preference/rare codon proportion, corresponding amino acid resistance gene translation and cell growth is established, and the relative content of phenylalanine for exogenous biosynthesis in cyanobacteria cells can be reflected in real time by detecting the real-time growth state of the cyanobacteria cells under resistance screening pressure.
