Enzymatic Synthesis of Astaxanthin n-Octanoic Acid Esters

open access: yesJournal of Oleo Science, 2008
We examined the enzymatic synthesis of astaxanthin n-octanoic acid esters. Carriers for the immobilized enzyme and reaction conditions such as water content, reaction temperature, and time were examined using Candida cylindracea lipase (Lipase OF). Lipase OF) immobilized by a hydrophobic anion exchange resin (10% w/w content of lipase) gave the best ...

Carotenoid accumulation in Haematococcus pluvialis in mixotrophic growth [PDF]

open access: yes, 2001
The microalga Haematococcus pluvialis was cultured with NaNO3 from 0 to 1 g l−1 and optimal growth was obtained at 0.15 g l−1. Sodium acetate and malonate (from 0 to 2% w/v) enhanced the accumulation of astaxanthin three and five times higher ...
