Overview of extraction of astaxanthin from Haematococcus pluvialis using CO2 supercritical fluid extraction technology vis-a-vis quality demands

open access: yes, 2021
Microalgae biomass have been used as a source of nutrient-rich food, feed, and health-promoting compounds. Among the several commercially available microalgae, Haematococcus pluvialis is the most abundant source of natural astaxanthin (3, 3'-dihydroxy-β,

The Biosynthesis of Astaxanthin-XIII

open access: yesNIPPON SUISAN GAKKAISHI, 1972
The carotenoids of crab, Portunus trituberculatus, have been separated by absorption chromatography and further characterized by their absorption spectra and their behavior on the column. In some cases, reactions for specific functional groups were performed.

Effects of non-fish based raw materials on the fish muscle quality of salmonids [PDF]

open access: yes, 2013
Salmonids are considered as fatty fish and a healthy food. They are characterized by a high proportion of n-3 long chain polyunsaturated fatty acids (n-3 LCPUFA).

Cobalt Single‐Atom Nanozyme for Enhanced Intestinal Radioprotection and Tumor Radiosensitization via Bidirectional ROS Modulation

open access: yesAdvanced Science, EarlyView.
Orally administered, pH‐responsive Co‐SAN exerts dual functions: in the alkaline intestinal milieu, it scavenges reactive oxygen species (ROS) and suppresses the PI3K/AKT pathway and NETs formation, thus providing radioprotection; whereas in the acidic tumor microenvironment, it generates ROS and alleviates hypoxia, thereby enhancing radiosensitization.

Bioeconomy, sustainability, and digital technologies in Haematococcus lacustris biomass and astaxanthin production: advances and outlook

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Astaxanthin is a carotenoid with strong antioxidant properties, used in research on cancer treatment, ocular injuries, and neurological disorders. When produced by the microalgae Haematococcus lacustris, its antioxidant potential is even higher than that of the synthetic molecule, making it particularly attractive for pharmaceutical and ...

Preparation of astaxanthin-loaded liposomes: characterization, storage stability and antioxidant activity

open access: yesCyTA - Journal of Food, 2018
Astaxanthin-loaded liposomes were prepared by employing a thin-film ultrasound method with the utilization of soy phosphatidylcholine. The preparation conditions of astaxanthin-loaded liposomes were optimized through response surface methodology.

Enabling Bioprocess Upscaling Prediction Through Hybrid Modelling and Transfer Learning Under Small‐Data Scenarios

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Accurate prediction of bioprocess scale‐up is critical for accelerating the deployment of novel and sustainable biomanufacturing systems. However, this remains challenging as multi‐scale data is expensive to generate and mechanistic understanding is often incomplete, leading upscaling decisions to rely heavily on empirical expertise.
