Abstract: Provided is a recombinant microorganism including at least two genes for producing itaconic acid and its derived monomers, and the at least two genes are located on the same expression vector. The at least two genes include one encoding cis-aconitic acid decarboxylase and the other one encoding aconitase, and the genome of the recombinant microorganism includes a gene encoding the molecular chaperone protein GroELS. Also provided is a method for producing itaconic acid by using the microorganism.

Abstract: A Escherichia coli strain for producing 5-aminolevulinic which has double pdxY genes is provided. A method of producing 5-aminolevulinic acid is provided, the method comprises providing the above Escherichia coli; and inoculating the above Escherichia coli into liquid modified M9 medium containing carbon source, IPTG, glycine, succinic acid and pyridoxal to cultivate the above Escherichia coli thereby producing 5-amino-levulinic. By the above Escherichia coli and the method of producing 5-aminolevulinic acid, the strain with high growth rate and 5-aminolevulinic productivity and the mothed of quickly producing 5-aminolevulinic acid with high 5-aminolevulinic productivity are provided.

Abstract: Provided is a non-naturally occurring microorganism capable of producing cadaverine, wherein the microorganism is genetically modified to overexpress lysine decarboxylase and pyridoxal kinase. Also provided is a method for producing cadaverine by using such microorganism without adding external pyridoxal 5?-phosphate.

Abstract: A tracer particle is provided.
