Advances in microbial production of 5-aminolevulinic acid

Abstract:

5-aminolevulinic acid is the key intermediate of the tetrapyrrole biosynthesis pathway in organisms and has broad application potentials. This review summarized and discussed recent progress in microbial production of 5-aminolevulinic acid, including screening, isolation and mutation of microbes to produce 5-aminolevulinic acid; microbial whole-cell transformation to synthesize 5-aminolevulinic acid depending on the C4 pathway; construction of high-yield 5-aminolevulinic acid producing strains by metabolic engineering. Finally, future research directions in microbial production of 5-aminolevulinic acid were addressed.
