Summary: The study found that microwaves were most effective for lipid extraction from Nannochloropsis oceanica, while ultrasound was more efficient for Nannochloropsis gaditana. The choice of cell disruption process should take into account various parameters such as the type of microalgae studied, total lipid extraction, desired fatty acids, and energy consumption.

Summary: In this study, a rapid cell rupture method using glass beads was selected for the lysis of spent brewer's yeast to obtain beta-glucans. The optimal parameters for cell lysis were found to be a cell suspension concentration of 5%, a ratio of yeast/glass beads of 1:2, and a vortexing cycle of 3, with a disruption efficiency of 99.8%. The beta-glucan fraction extracted from the optimal sample showed a high content of beta-glucan.

Summary: This study investigated the effective carotenoid extraction from Phaffia rhodozyma biomass by improving the extraction process and evaluating color properties, antioxidant activity, and energy consumption. The results showed that the adapted acetone procedure and freeze-drying pretreatment achieved high carotenoid extraction and antioxidant activity. Economic evaluation indicated that the adapted process was more cost-effective than the standard process.

Summary: The efficiency of microbial fuel cells (MFCs) relies on the charge transfer capability from microbes to anodes, with redox mediators playing a crucial role. This study looked at the influence of 2-methyl-1,4-naphthoquinone (menadione (MD)) on yeast cells and found that baker's yeast cells were more resistant to dissolved MD. The maximal calculated power output of a designed baker's yeast-based MFC cell anode was 0.408 mW/m(2) at 24 mV.

Summary: Non-enveloped virus-like particles (VLPs) are protein nanoparticles with great potential for biopharmaceutical applications. However, their large size poses challenges for conventional protein downstream processing (DSP). Size-selective separation techniques offer a solution by exploiting the size difference between VLPs and host-cell impurities. This review discusses the principles, applications, and benefits of size-selective separation techniques in DSP of VLPs and their subunits.

Summary: The study examines the time-varying effect of income inequality on renewable energy consumption, with a short period of negative relationship between 1995 and 2002, followed by a switch to positive relationship from 2010 onwards. Different measures of renewable energy show heterogeneous effects of income inequality, emphasizing the need for policymakers to consider the channels through which income inequality works when developing dynamic policies for renewable energy uptake or transition.

Summary: The study utilizes non-parametric modeling technique to examine the time-varying impact of renewable and non-renewable energy consumption on economic growth from 1990 to 2015. The results indicate that non-renewable energy consumption has a significant positive effect on economic growth in OECD countries, while the impact of renewable energy is statistically insignificant in most parts of the study period. In non-OECD countries, both renewable and non-renewable energy consumption promote economic growth, suggesting the potential role of developing countries in the transition to renewables.

Summary: Due to environmental concerns and consumer demand, there is a need for alternative pasteurization techniques to produce safe and high-quality milk in a sustainable manner. In this study, a new non-thermal moderate electric field (MEF) system was developed, which significantly reduced energy consumption, processing time, and cost compared to conventional thermal pasteurization methods, while also achieving better bacterial inactivation.

Summary: Energy is crucial for driving and sustaining economic growth in a country. This study investigates the relationship between energy consumption and economic growth in selected developed and developing countries from 1993-2019. Using the Pedroni co-integration method, the study determines the long-term relationship between economic growth and energy consumption. The results show that energy consumption has a positive and significant impact on economic growth in both groups of countries.

Summary: The study examines the effects of forest plantation area, renewable energies, GDP, and technological innovation on CO2 emissions in New Zealand. It finds that planted forest areas can reduce CO2 emissions in the long run but not in the short run. Non-renewable energy consumption is the major contributor to CO2 emissions in both short and long term. Technological innovation and renewable energy consumption can reduce carbon emissions in the short term but contribute to increased CO2 emissions in the long term. The forest plantation areas in Manawatu-Whanganui and Gisborne are important regions for reducing CO2 emissions.
