Summary: In this study, ultrasonic pretreatment was used to accelerate the aqueous enzymatic extraction of gardenia fruit oil. The extraction conditions of two enzymes were optimized using the response surface method. Ultrasonic pretreatment reduced the protein content in the raw material and increased the fluidity of the powder. The oil extracted by ultrasound-assisted aqueous enzymatic extraction showed better quality and higher contents of tocopherol, squalene, and polyunsaturated fatty acids.

Summary: Enzyme-assisted aqueous extraction (EAAE) is a green and scalable method for producing fish oil and protein hydrolysates. This study investigated the effects of different parameters on emulsion formation, oil recovery, and crude oil composition during EAAE of Baltic herring. The results showed that EAAE resulted in a lower content of phospholipids and docosahexaenoic acid compared to solvent-extracted oil. Changing the fish to water ratio and adding ethanol led to a significant reduction in emulsion formation and increased oil recovery.

Summary: Recent research shows that high-molecular weight disinfection byproduct (DBP) fractions contribute more to cytotoxicity than the one-to two-carbon DBPs currently of concern. Peptides and lipids are major DBP precursors in water supplies. This study focuses on the analysis of chlorine byproducts of tyrosine and oleic acid to characterize high-molecular weight DBPs. The presence of these DBPs in drinking water and their cytotoxicity levels are investigated.

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: Colloid-enhanced ultrafiltration (CEUF), including micellar-enhanced ultrafiltration (MEUF) and polymer-enhanced ultrafiltration (PEUF), has shown promising potential in removing sulfate ions from aqueous solutions. PEUF has advantages over MEUF in terms of higher retention, cleaner effluent, and higher adsorption capacity, but faces challenges of severer flux decline and membrane fouling. Membranes with higher molecular weight cut-off can be used to overcome these disadvantages.

Summary: Residues from biomass processing/harvesting can be converted to high-value chemicals and fuels through pyrolysis. Pyrolysis oils derived from lignocellulosic biomass, particularly hemp residues, have potential as sources of bio-phenols. The extraction and recovery of phenolic compounds from pyrolysis oils require further investigation for optimizing pre-treatment, extraction, and analytical techniques. Considerable progress has been made in producing cost-effective renewable phenolic resins, but challenges remain in achieving satisfactory quality and low cost.

Summary: This study demonstrates the cost-effective production of biosurfactants using waste substrates and optimized cultural conditions. By using waste cooking oil as the sole carbon source, a biosurfactant with high stability in thermal, pH, and salinity conditions was successfully produced. The combination of indigenous bacteria and no-cost carbon sources from waste shows great promise in reducing production costs and producing biosurfactants tailored for harsh environments like the North Atlantic.

Summary: Gasification kinetics of six chars from residual origin were studied under relatively low temperature, low CO2, and high H2O partial pressures. The Random Pore Model (RPM) showed the best fit to experimental results, but the selection of the reaction model depended on the ash composition, specifically the presence of alkali and alkaline earth metals. Chars with ash content higher than 30% wt. were modeled with the RPM model, while chars with the highest K/Si ratio required modified versions of the RPM to accurately predict reaction rates. Textural properties played a key role in determining reaction parameters, such as the pre-exponential factor and activation energy, for chars with similar ash content and composition.
