Summary: This study investigates the bio-fractionation of Paracoccus carotinifaciens biomass to obtain Astaxanthin (ASX) and related carotenoids using the solvent N,N-dimethyl cyclohexylamine (DMCHA). DMCHA showed higher extraction yield compared to acetone and ethanol, with 88.2% of the extracted ASX being recovered after washing. The study also demonstrated the possibility of extracting carotenoids with recycled solvent, with a minimal efficiency drop and lower energy footprint.

Summary: This study found that spraying loquat trees with 0.1% zinc sulphate resulted in increased levels of soluble sugars and decreased acid contents in loquats. The activities of key enzymes were measured and gene expression analysis revealed the potential involvement of certain enzymes and genes in regulating sugar-acid metabolism in loquats.

Summary: This study examined the effects of Paracoccus carotinifaciens supplementation on egg production and quality, as well as the dynamics of carotenoid levels in the egg yolk and the taste of astaxanthin-rich egg yolk. The results showed that supplementation did not affect production performance or egg quality, and the levels of astaxanthin in the egg yolk reached saturation after seven days of supplementation before decreasing. Additionally, supplementation did not affect the taste of the egg yolks. Overall, understanding the incorporation of astaxanthin into egg yolks can be beneficial for value-added egg production.

Summary: Feeding laying hens diets containing astaxanthin with higher Z-isomer ratios significantly increased astaxanthin concentration in egg yolk and color fan score. Z-isomers of astaxanthin exhibit higher bioavailability compared to all-E-isomer, leading to greater egg yolk-accumulation efficiency.

Summary: The study found that the pitting and erosion corrosion of aluminium brass condenser tubes in a seawater cooled nuclear power station was caused by inadequate ferrous sulphate dosing and relatively excess chlorine concentrations. Microscopic studies and surface chemical analysis were carried out to understand the mechanism of corrosion, with major corrosion product identified as copper chloride. Detailed XPS study has provided valuable supportive data to elaborate on the mechanism of Al-brass chemical corrosion.

Summary: The effects of high-temperature supercritical CO2 extraction on Z-isomerization and recovery of carotenoids from Paracoccus carotinifaciens were investigated. The study found that high-temperature extraction increased the Z-isomer ratio and improved carotenoid recovery. Higher pressure and ethanol content resulted in lower Z-isomer ratios and higher recoveries of carotenoids.

Summary: The study concluded that ferrous sulphate, iron hydroxide polymaltose complex, and ferrous ascorbate have comparable efficacy and safety profiles in the treatment of iron-deficiency anaemia during pregnancy. While ferrous ascorbate showed significantly higher haemoglobin levels compared to ferrous sulphate at day 90, overall the three groups showed similar levels of haemoglobin.

Summary: Detonation nanodiamond (ND) has shown its potential to improve the mechanical and biological properties of gelatin-based hydrogels. In this study, natural cross-linker tannic acid (TA) and ferrous sulphate (FS) were used to optimize the swelling and disintegration of extrudable and 3D printable gelatin hydrogels. The improved dispersion of ND particles helped to improve the mechanical properties and stability of the hydrogels.

Summary: The feasibility of ferrous sulphate solution for remediation of hexavalent chromium contaminated soil was explored through injection tests under different pressures. The results showed that the injection of FeSO4 solution at different pressures caused a decrease in hydraulic conductivity and the formation of mixed iron(III)/chromium(III) hydroxide. Fe(II) mobility was stronger at higher pressures and the maximum iron increment was observed at 100 kPa. The injection pressure of 70 kPa was found to be the most efficient for remediation with a range of 87.43-95.12% efficiency.
