- Editorial - Special issue CHEMPOR 2023 – 14th International Chemical and Biological Engineering ConferencePublication . Pinho, Simão; Barreiro, FilomenaThe 14th International Chemical and Biological Engineering Conference (CHEMPOR 2023), organized by Bragança Polytechnic University and the Portuguese Engineers Association, was held in Bragança, Portugal, on September 12–15, 2023. CHEMPOR 2023 focused on recent developments in various settings, including biorefinery, biotechnology, energy and environment, innovative materials, and the creation and design of novel reaction and separation processes, always foreseeing industrial applications for a sustainable future. The conference served as a melting pot to celebrate creativity, diversity, and friendship among participants, fostering the exchange of ideas and enabling fruitful interactions. It brought together professionals from the academic, industrial, scientific, and technological communities, uniting over 300 delegates from 12 countries. This collection of papers from CHEMPOR 2023 vividly illustrates how biological and chemical engineers are tackling the major societal challenges of our time. They highlight converging initiatives to promote sustainability through a circular economy where materials are valued and renewable. The papers present contemporary contributions in wastewater treatment, waste and biomass valorization, energy transition solutions, efforts to mitigate climate change, and bio-based approaches to produce, separate, and purify valuable compounds using ionic liquids or eutectic solvents. The selected works featured in this special issue represent an excellent reflection of the conference spirit. The attendees' dedication to seeking innovative solutions and producing high-quality scientific outputs also stood out. Finally, we want to express our profound appreciation to all the participants and our enormous gratitude to all our sponsors and associated scientific journals and publishers. In particular, we acknowledge the editorial team of Separation and Purification Technology, especially Bart Van der Bruggen and Raquel Aires-Barros, for their significant support and enthusiasm.
- Editorial: Microbial safety of animal-based food productsPublication . Andrade, María J.; Álvarez, Micaela; Rodrigues, PaulaThe studies gathered in this Research Topic focus on several key areas to ensure the safety of animal food products. Firstly, rapid pathogen detection is being improved through technologies like SWIR-HSI combined with advanced machine-learning techniques. Secondly, the use of natural antimicrobials, such as essential oils delivered via liposomes, is being explored to combat microbial development while minimizing negative impacts on food quality. Thirdly, investigations have revealed a link between high crayfish consumption and rhabdomyolysis, emphasizing the need to control the toxins in the food chain. Finally, studies on the relationship between diet and colorectal cancer have suggested a potential inverse association between high fish intake and risk of developing colorectal adenoma, suggesting a possible preventative role for fish consumption. These combined efforts aim to enhance the safety and quality of animal-derived foods through advanced detection methods, natural preservation strategies, and a broader understanding of foodborne threats.
- Focus Issue: Innovation Pathways to Sustainability in MountainsPublication . Balsiger, Jörg; Zimmermann, Anne B.; Azevedo, João C.; Schmidt-Vogt, DietrichThis editorial examines the role of innovation in promoting sustainable development in mountainous regions. It critiques simplistic narratives that frame mountains primarily as sources of renewable energy or as areas needing to be relocated due to climate risks, arguing that such perspectives neglect regional diversity and the capacity for action of local actors. The authors propose a multidimensional understanding of innovation that includes technological, social, institutional, and knowledge-based practices rooted in local contexts. The issue brings together studies illustrating how community practices, circular economy strategies, participatory governance, and knowledge co-production can address environmental and socioeconomic challenges. Overall, mountainous regions are presented as important locations for experimentation and learning in transitions towards sustainability.
- Focus Issue: Woodland Resurgence and Sustainability in Mountains—Patterns, Drivers, and Social-Ecological ConsequencesPublication . Schmidt-Vogt, Dietrich; Azevedo, João C.; Grau, H. Ricardo; Nowreen, Sara; Portner, BrigitteIn recent decades, the resurgence of forests and other woodlands has become apparent in different regions of the world, challenging the perception of deforestation as the dominant land cover change pattern. Woodland resurgence has been particularly pronounced in mountain areas, where conditions limit the scope for agricultural mechanization and rural outmigration has favored land abandonment. In addition, many governmental and nongovernmental initiatives to promote forest management, restore forests, protect biodiversity, and conserve ecosystem services have focused on mountain areas.
- Note: Cytonuclear patterns of a honey bee population from the Azores show a stable population at the nuclear but not at the mitochondrial DNA levelPublication . Henriques, Dora; Lopes, Ana Rita; Costa, Maíra; Quaresma, Andreia; Doblas-Bajo, Mónica; Pinto, M. AliceThe Azores archipelago has been the stage for multiple introductions of Apis mellifera from varying origins, which have led to widespread admixture and the existence of phenotypically and genotypically heterogeneous populations. This is evident on the São Miguel Island, where the historically introduced black phenotype of A. m. iberiensis (lineage M) co-exists with the contemporaneously introduced yellow phenotype of C-lineage ancestry. Interestingly, the cytonuclear markers used herein revealed that C-lineage ancestry is residual at the nuclear level for both the black (5.82 ± 1.66%) and yellow (5.91 ± 1.85%) phenotypes, although this is more pronounced at the mitochondrial level (27.27% for black and 14.74% for yellow). While the C-lineage contribution has remained stable at the nuclear level for over 20 years, there has been a recent decrease in the proportion of C-derived mitotypes.
