Abstract

Brown seaweed A.nodosum has been widely used for feed and biostimulant purposes for many years. However, due to its high-water content (ranging >80% MC) it presents challenges like increasing costs of transportation and storage for downstream processing. Therefore, an effective dewatering step is essential to reduce the moisture content, concentrate the biomass and improve handling and processing efficiency. Mechanical dewatering is commonly applied as a pretreatment step in biorefining as it removes readily mobile water and reduces the moisture available for microbial deterioration during handling and storage. However, the efficiency of mechanical dewatering can be limited by the strong water-holding capacity of seaweed tissues and cell-wall components, resulting in substantial residual moisture in the pressed biomass. In this context, this study evaluates calcium chloride (CaCl2 ) and magnesium chloride (MgCl2 ) as pretreatment agents prior to hydraulic pressing of A. nodosum, assessing their effects on dewatering efficiency and the partitioning of protein-bound amino acids between the liquid and solid fractions.

Abstract

The valorization of seafood by-products is often framed as a technical opportunity, yet adoption in practice depends on whether small and medium-sized enterprises (SMEs) can embed new systems in their operational, economic, spatial, and regulatory realities. Drawing on survey-based evidence from Greek fisheries and seafood enterprises, the analysis identifies key operational and economic constraints and translates them into a configurational model of adoption credibility for blue SMEs. In the proposed TIDE framework, adoption credibility depends on alignment across four distinct dimensions: Technological Fit, Institutional Enablement, Deployment Fit, and Economic-Organizational Fit. The framework links firm-level conditions with techno-economic performance metrics, including cost–benefit indicators (e.g., CAPEX/OPEX per unit, avoided disposal costs, payback period) and system optimization variables, such as throughput variability and process efficiency. The theoretical insights illustrate that optimal valorization outcomes depend on the alignment between system design and SME-specific constraints, particularly in relation to deployment models (on-site units, shared hubs, and mobile services). The study provides a structured approach for integrating cost–benefit analysis and technical optimization with real-world adoption conditions, offering practical guidance for designing scalable, low-CAPEX/OPEX valorization solutions.

Abstract

The widespread use of per- and polyfluorinated substances (PFAS) over the past several decades has resulted in extensive soil contamination. Soil serves as a significant reservoir and a potential long-term source of PFAS. While the high stability and persistence of PFAS facilitates accumulation in soil, some PFAS, such as several perfluoroalkyl acids (PFAAs), exhibit relatively high mobility allowing them to leach into the surrounding environment and possibly travel long distances. Remediation of contaminated sites is necessary to avoid severe environmental and human impacts. Soil stabilization represents a non-destructive soil remediation method which involves incorporation of binding materials (sorbents) into the contaminated soil to reduce contaminant leaching and bioavailability.

Abstract

Abstract The use of Saccharomyces cerevisiae to ferment alcoholic beverages is an ancient tradition, with genetic evidence indicating origins in Neolithic Asia, although the domestication process of the species is not fully understood. Kveik is a group of traditional yeasts used in farmhouse brewing in western Norway preserved through generations of rural brewing practice. While recent studies have highlighted the distinctiveness of kveik, its precise phylogenetic position, genetic diversity, and domestication history remain unclear. We performed whole-genome sequencing on 64 isolates from 25 traditional brewing cultures from Western Norway selected using cultural heritage criteria and generated telomere-to-telomere assemblies for selected strains. Phylogenomic and population genetic analyses reveal that kveik strains form a paraphyletic and early-diverging group with respect to other domesticated S. cerevisiae strains. Most strains exhibit low diversity among isolates from the same brewing culture, strong geographic clustering, and little evidence of gene flow or admixture. Mitochondrial genomes and Ty1 retrotransposon profiles corroborate this distinct lineage history. We further show that previously reported signals of gene flow between kveik and Asian fermentation strains are likely artifacts caused by population structure and selection. Divergence time estimates suggest that the common ancestor of beer, kveik, and other liquid-phase fermenting strains originated from ancestral populations 4,000 to 8,000 years ago. Our genomic resource sheds light on yeast evolution and domestication. Kveik likely comprises some of the oldest domesticated lineages in continuous use until today, connecting intangible cultural heritage to an early genetic origin.
