Enhanced Production of Astaxanthin and Zeaxanthin by Paracoccus Sp. LL1 Through Random Mutagenesis

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Astaxanthin, a high‐value carotenoid with potent antioxidant and anti‐inflammatory activities, is increasingly in demand in various industries. This study reports the successful enhancement of astaxanthin and zeaxanthin production in Paracoccus sp. LL1 through random mutagenesis using ethyl methanesulfonate (EMS).
