<p> This document reveals 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 by a shorter metabolic pathway, and therefore reaches a higher level of end products (eg, astaxanthin) with desired stereoisomeric form and / or esterified form. </p> |
