A Novel Bifunctional Wax Ester Synthase Involved in Early Triacylglycerol Accumulation in Unicellular Green Microalga Haematococcus pluvialis Under High Light Stress

Frontiers in Bioengineering and Biotechnology, 2022
The bulk of neutral lipids, including astaxanthin esters and triacylglycerols (TAGs), are accumulated in the green microalga Haematococcus pluvialis under high light (HL) stress. In this study, a novel bifunctional wax ester synthase (WS) gene was cloned

Chlorella vulgaris biorefineries: sustainable biofuels and high‐value carbon capture

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 4, Page 1683-1707, July/August 2026.
Abstract Global reliance on fossil fuels has created urgent economic and environmental challenges, yet large‐scale use of algal biomass remains limited by production costs. Industrial scaling is constrained by inefficient harvesting and the technical challenges of processing recalcitrant cell walls.

Kombucha Tea Fortified With Spirulina Maxima and Haematococcus pluvialis: Impact on Physicochemical Properties, Bioactive Profile, and Antioxidant Capacity

Food Science &Nutrition, Volume 14, Issue 7, July 2026.
The fortification of kombucha tea with microalgae significantly enhances its bioactive profile, where Spirulina maxima (4%) acts as the optimal fermentation enhancer by increasing phenolics and organic acids, while Haematococcus pluvialis (4%) serves as the best astaxanthin source, with both microalgae contributing to elevated antioxidant activity ...

Update of the list of qualified presumption of safety (QPS) recommended microbiological agents intentionally added to food or feed as notified to EFSA 24: Suitability of taxonomic units notified to EFSA until March 2026

EFSA Journal, Volume 24, Issue 7, July 2026.
Abstract The Qualified Presumption of Safety (QPS) process was developed to provide a harmonised safety assessment approach to support EFSA Scientific Panels and Units. The QPS approach assesses the taxonomic identity, body of knowledge and safety of microorganisms intentionally added to the food and feed chain.
