Plastid Engineering for Photosynthesis‐Driven Synthesis of Hyaluronic Acid in Tobacco

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Hyaluronic acid (HA) is a glycosaminoglycan composed of alternating units of N‐acetylglucosamine and glucuronic acid. High moisture retention, viscoelasticity and biocompatibility are unique features that make HA polymers attractive compounds for medical applications and aesthetic purposes.

Extraction of Astaxanthin from Haematococcus pluvialis and Preparation of Astaxanthin Liposomes

open access: yesMolecules
Astaxanthin has 550 times more antioxidant activity than vitamin E, so it can scavenge free radicals in vivo and improve body immunity. However, the poor stability of astaxanthin becomes a bottleneck problem that limits its application. Herein, Haematococcus pluvialis (H.
