Summary: This study investigated the impact of different suspension media and additives on the stability of astaxanthin isomers, identifying several vegetable oils and antioxidants that significantly improved stability. It was found that the (9Z)-astaxanthin demonstrated higher stability compared to other Z-isomers. These findings suggest the importance of selecting suitable suspension mediums and antioxidants for maintaining astaxanthin concentration and Z-isomer ratio over time.

Summary: The effects of dietary astaxanthin from different sources on growth, pigmentation, and physiological function in Oncorhynchus mykiss were studied. Astaxanthin supplementation improved pigmentation, growth, intestinal morphology, crude protein content in dorsal muscle, and decreased cholesterol levels and enzyme activity in plasma. Astaxanthin also enhanced antioxidant capacity and stimulated innate immune responses in fish.

Summary: By analyzing the microbiological properties, proximate composition, pH value, fatty acid composition, peroxide value, free fatty acids, histamine, and water holding capacity in rainbow trout fillets, it was found that additives such as 50mg vitamin E, 200mg vitamin E, 500mg probiotics, 50mg astaxanthin, and 500mg rosemary extract not only protected the physicochemical properties of the fish fillets but also maintained the content of polyunsaturated fatty acids. Among them, the feed containing 500mg probiotics and 50mg vitamin E had the best effect on maintaining the quality of rainbow trout fillets.

Summary: In this study, Corynebacterium glutamicum was engineered to produce astaxanthin by heterologous gene expression. An efficient extraction process using ethanol was established, and the optimal conditions were determined to be 90% ethanol, 60 degrees C, and a biomass-to-solvent ratio of 5.6 mg(CDW)/mL(solvent). The purified astaxanthin obtained showed high antioxidative activity.

Summary: Recent genome editing studies have focused on examining and modifying plant architectural phenotypes in cereals, aiming to improve crop yield and quality by optimizing plant structure. The profound impact of plant architecture on agronomic performance has led to a growing interest in controlling architectural traits in staple crops like rice through genetic and hormonal regulation.

Summary: Light plays a crucial role in regulating various developmental processes in higher plants, including the biosynthesis of chlorophylls, carotenoids, and phytosterols. The coordinated expression of MEP pathway genes, chlorophyll, carotenoid, and tocopherol pathway genes during de-etiolation reflects changes in corresponding metabolites levels. Light-responsive cis-regulatory elements in the promoter regions of light-upregulated genes provide a mechanistic basis for the observed phenotype during de-etiolation.
