Summary: This study investigated the nutritional compositions of marine microalgae from different phyla under the same conditions. Results showed variations in protein, carbohydrate, lipid, amino acid, fatty acid, vitamin, and pigment compositions. The principal component analysis and grey relational analysis were performed to evaluate their nutritional values. These findings have significant implications for the utilization of marine microalgae nutrients in aquaculture and other industries.

Summary: Microalgae-derived fatty acids, particularly those from S. limacinum, show potential as tyrosinase inhibitors to treat hyperpigmentation disorders. These fatty acids demonstrate dose-dependent increase in tyrosinase activity and have lower toxicity to melanoma and keratinocyte cells.

Summary: This study cloned fatty acid desaturases and elongases genes from Ruditapes philippinarum and analyzed their tissue distributions. The expressions of these genes were significantly higher in the digestive glands and intestine. Feeding the bivalves with microalgae of varying fatty acid compositions showed that the bivalves can modulate gene expressions to adapt to different dietary compositions and have the capacity for LC-PUFA biosynthesis.

Summary: Microalgae are a valuable natural resource for producing a variety of value-added products. The optimal light intensity for their growth is around 26,400 µmol photons m(-2) s(-1), with higher intensity leading to increased lipid synthesis and triacylglyceride content. Light intensity also affects the synthesis of fatty acids and carotenoids in microalgae biomass. Additionally, combining light with other stresses can enhance the productivity of algae.

Summary: The study found that replacing fishmeal protein with Chlorella vulgaris and fish oil with a blend of Schizochytrium sp. and Microchloropsis gaditana did not have adverse effects on the growth, feed utilization, muscle fatty acid composition, and liver histology of Sparus aurata. The replacements did lead to an increase in lipid retention and deposition mainly in the liver, but no other significant changes were observed. The study suggests that these replacements can be made without negatively impacting the growth performance, feed efficiency, proximate composition, and muscle EPA and DHA levels of the fish.

Summary: Through genetic identification and analysis of nutrient compositions, the study found that the edible broods of Vespa hornets in China and Korea contain varying levels of protein and amino acids. The high content of unsaturated fatty acids in hornets could potentially provide health benefits, including reducing cardiovascular disorders and inflammation. Additionally, the high minerals content in hornets, such as iron, zinc, and a high K/Na ratio, may help mitigate mineral deficiencies in populations with inadequate nutrition.

Summary: The hexane extract of Chaetoceros muelleri showed high activity against various bacteria species, especially Mycobacterium tuberculosis, while the methanol extract was inactive against all tested microorganisms. Other extracts demonstrated antibacterial potential and could be promising for the development of new antibacterial compounds.

Summary: The study aimed to analyze biomass production and fatty acid profiles in Coccomyxa AP01 under different nutritional conditions. Results showed that nutrient deprivation induced significant changes in fatty acid profiles, with phosphate deprivation leading to high biomass yield and production of valuable saturated and polyunsaturated fatty acids. Coccomyxa AP01 is considered a promising source of various fatty acids for commercial purposes, including biodiesel production, pharmaceutical and cosmetic applications, and aquaculture fish feeds.

Summary: The study investigated the effects of convective drying at different temperatures on the drying kinetics and quality parameters of Salicornia fruticosa, finding that the Henderson model was the most suitable for predicting equilibrium moisture content. The Midilli-Kucuk model showed the best fitting to drying curves. Drying had significant effects on two quality parameters, with the optimum drying temperature identified as 70 degrees C.

Summary: The study introduces a novel enzyme improvement platform, Immobilized Biocatalyst Engineering (IBE), which integrates protein engineering (PE) and enzyme immobilization (EI) to simultaneously enhance biocatalysts. The IBE approach allows for the evaluation of thousands of variants in a short time, leading to the discovery of highly stable and active heterogeneous biocatalysts that show significant improvement over traditional methods. This innovative approach increases the probability of finding suitable biocatalysts for highly demanding processes.

Summary: This study demonstrates the potential enzymatic production of galactaric acid from galacturonic acid by protein engineering of glucose oxidase. Two variants of glucose oxidase with amino acid substitutions F414K and Y68W were identified and showed catalytic activity towards galacturonic acid with minimal glucose oxidation activity. Further experiments indicate structural and functional differences in the variants. Additionally, the study shows the possibility of simultaneous pectin depolymerization and galactaric acid production from citrus pectin using engineered glucose oxidases and pectinase.
