TL;DR
H2O2 treatment is suitable for improving the high-value antioxidant levels, and a short-term treatment can induce its rapid accumulation, as it showed the strongest correlation with H2O2 concentration and astaxanthin content.
Multi-stress induction represents a promising strategy for enhancing astaxanthin accumulation in Haematococcus lacustris; however, productivity optimization requires balancing cellular enrichment with biomass formation. This study investigates the main effects of three critical process variables, namely temperature, CO...
The industrial cultivation of Haematococcus pluvialis for astaxanthin is constrained by a fundamental trade-off: stress promotes astaxanthin accumulation but suppresses growth. To overcome this, we applied adaptive laboratory evolution (ALE) under progressive high acetate stress (2.5-5-7.5 g/L NaAc). This approach gen...
This study demonstrates the combined optimization of isozyme combination and environmental stress to elevate the synthesis of astaxanthin and other carotenoids in D. salina, providing new research ideas and experimental evidence for the future construction of high-yield engineered algal strains.
Findings suggest that low-dose ethephon elicitation may be a simple strategy to enhance phycobiliprotein accumulation in Arthrospira platensis.
An effective strategy for improving astaxanthin biosynthesis is demonstrated and the industrial potential of BE1 for natural astaxanthin production is highlighted, demonstrating an effective strategy for improving astaxanthin biosynthesis.
