Summary: This study produced protein hydrolysates from microalgal Chlorella biomass using enzymatic hydrolysis, which showed cosmetic and nutraceutical properties. The hydrolysates had high degree of hydrolysis and bioactivities, including antioxidative and tyrosinase inhibition activities. The molecular weight of the hydrolysates was determined to be <= 2 kDa, and they contained essential amino acids meeting the human nutrient requirements. This highlights the potential use of enzymatically derived protein hydrolysates from microalgae in cosmetic and nutraceutical applications.

Summary: This study compared the enzymatic hydrolysis efficiency of wet, freeze-dried, and oven-dried microalgal biomass, with and without an acidic pretreatment. The results showed that wet microalgal biomass had a higher glucose yield compared to oven-dried biomass, possibly due to the hindered accessibility of enzymes in the cross-linked cells of the latter. Acidic pretreatment significantly improved the glucose recovery, with potential for direct saccharification process. The enzymatic hydrolysate of wet microalgal biomass was successfully used for ABE fermentation, producing 7.2 g/L of ABE, indicating its potential in bioalcohol fuel fermentation.

Summary: The study investigated the emulsifying behavior of untreated insoluble microalgae protein fraction and two of its hydrolysates obtained at different temperatures and acid concentrations. Emulsions with Hydrolysates 85 showed the smallest droplet size and highest apparent viscosity, with gravitational separation hindered as oil content increased. The results suggest that Hydrolysates 85 may be a good emulsifier for concentrated emulsion-based foods with high oil content.

Summary: To facilitate biomolecules extraction and bioaccessibility of Chlorella pyrenoidosa, a novel industry-scale microfluidization (ISM) was used to disrupt cells effectively. Microscope images showed ISM damaged cell integrity, disorganized cell wall structure, pulverized cell membrane and promoted the release of intracellular components. The decrease of particle size and the increase of ζ-potential also confirmed the cell disruption. The cell breakage ratio of sample treated at 120 MPa was 98%. Compared with untreated samples, total soluble solid content and protein extraction rate of the sample treated at 120 MPa increased by 2 degrees Brix and 12%. Protein was degraded by ISM, the release of intracellular protein and the reduction of molecular weight increased protein digestibility by 20% in in vitro gastric phase. Lipid yield and chlorophyll b content were also increased by ISM. These results provided a new solution to cell disruption of microalgae and expanded the application field of ISM.

Summary: This research focuses on the enzymatic hydrolysis of meat waste as a green technology to obtain high-value products. Optimized process variables for protein hydrolysis included pH 8.0, temperature 50°C, and Eo/So 0.16 AU/g, resulting in easily digestible and pleasant-tasting protein hydrolysates and collagen. For lipid hydrolysis, the optimal process variables were Eo'/So' 0.83 kLU/g, pH 8.0, and temperature 50°C, with unsaturated fatty acids being the predominant components. The combination of Alcalase and Resinase enzymes showed potential for simultaneous recovery of protein hydrolysates, collagen, and fatty acids.

Summary: With their ability to fix CO2 using sunlight, algae and microalgae are being studied for the production of proteins and valuable compounds. However, the successful utilization of algal biomass relies on effectively disrupting the recalcitrant cell wall. This study evaluated different methods to break up the cell wall and measured success by protein and carbohydrate release. The analysis also identified factors contributing to the robustness of the cell wall.

Summary: This study produced Azolla pinnata fern protein concentrate (AFPC) through alkaline solubilisation with isoelectric precipitation and investigated the effects of different proteases on the physicochemical, techno-functional properties, and biological activities of Azolla fern protein hydrolysates. The results showed that enzymolysis with all proteases decreased hydrophobicity, denaturation temperature, and secondary structures as the degree of hydrolysis increased. Techno-functional properties including water and oil holding capacities, emulsion properties, and foam stability were reduced with increasing hydrolysis, except for solubility and foaming capacity. Hydrolysis with all proteases had a positive effect on antioxidant and antibacterial activities. The study suggests the potential application of Azolla fern protein hydrolysates as nutraceutical and functional food ingredients.

Summary: This study investigated the effects of enzymatic hydrolysis and activated carbon decoloration on antioxidative activities and peptidomic patterns of microalgae protein hydrolysates using a peptidomic approach. Activated carbon decoloration significantly increased color lightness but decreased antioxidative activities and relative abundances of peptides, particularly aromatic amino acid containing peptides. Understanding the dynamics of production processes at a molecular scale can enhance the production and quality control of bioactive peptides from Auxenochlorella pyrenoidosa.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
