Abstract: Disclosed herein are recombinant polynucleotide sequences, vectors, host cells and methods for producing astaxanthin. The recombinant polynucleotide sequence is designed to provide a higher level of astaxanthin precursors via a shorter metabolic pathway, and thereby attains higher level of end products (e.g., astaxanthin) with desired stereoisomeric form and/or esterified form.
