To protect and sustainably use peat soils, it is important to maintain their high moisture content by keeping proper groundwater levels. This can be achieved by using existing water-retaining structures in their area, such as weirs and sluices. Beaver dams can also serve a similar function, as they block water outflow from peatlands, raising water levels and naturally retaining it. The water conditions created by beaver dams promote secondary environmental succession processes, leading to the sustainable use of environmental resources. The presented research focused on drainage–irrigation perspectives for a lowland fen in the face of hydrologic alterations and a search for proper organic soil and water management. The results of systematic observations of water level variability in the Mała riverbed were analysed, as well as in a selected area of the subsurface irrigation system, influenced by the presence of a beaver dam in the years 2015–2019. The research was conducted on a section of that system, used as permanent grassland in central Poland—the Solec site. Before the construction of the beaver dam, measurement results indicated the draining nature of the Mała River, supported by an extensive network of drainage ditches. After the construction of the beaver dam, water levels in the Mała River bed above the dam increased, as did groundwater levels in the adjacent area, up to 40 m from the riverbank. In the analysed site, the beaver dam caused the groundwater level to increase by 0.25–0.45 m in 2015, compared to the neighbouring quarter, located outside the range of the dam. At observation points A and B, located 40 m and 115 m from the river, respectively, the groundwater table was usually within the acceptable drainage standards for organic soils (complex C—dry), while in the case of point C, located 240 m from the river (medium mineral soil complex), the water table was mostly below the maximum drainage standard. The conducted groundwater table depth estimations were purposely compared to the existing standards to further outline the impact of selected measures, e.g., the bever dams, to maintain hydrologic conditions of a managed fen.
Comprehensive Triterpenoid Saponin Profiling of Beta vulgaris L. Root Extracts and Their Functional Application in Cleansing Gels
(MDPI, 2026-09-29) Gierałt, Bartosz; Malinowska, Magdalena Anna; Tekieli-Galas, Anna; Kowalczyk, Mariusz; Spórna-Kucab, Aneta
Plant-derived bioactive ingredients are increasingly valued in cosmetic formulations due to their multifunctionality and natural origin. This study evaluated beetroot (Beta vulgaris L.) extracts as plant-derived surfactant-supporting ingredients in cleansing gels, with DPPH radical-scavenging response assessed as a secondary formulation-level endpoint. Three cultivars—Dark Red Round (red), Boldor (yellow), and Snow Ball (white)—were characterized for triterpenoid saponin composition and functional performance. Unlike previous studies focused primarily on the phytochemical characterization of beetroot saponins, the present work integrates cultivar-dependent chemical profiling with comparative evaluation of the corresponding extracts in the same cleansing formulation. UHPLC–CAD–QTOF–HRMS/MS analysis tentatively annotated 30 triterpenoid saponins and revealed cultivar-dependent differences. Semi-quantitatively estimated total saponin concentrations were 17.5, 15.1, and 11.6 g/kg dry extract for Dark Red Round, Boldor, and Snow Ball, respectively, with oleanolic acid-based saponins predominating. Cleansing gels containing 1% (w/w) beetroot extract were evaluated for physicochemical, rheological, and functional properties. Extract-enriched gels showed increased foamability, cultivar-dependent foam stability, and pseudoplastic shear-thinning behavior. Surface tension remained substantially lower than that of water but increased moderately after incorporation of the extracts, indicating modification rather than further surface-tension lowering of the existing surfactant system. DPPH screening showed cultivar-dependent radical-scavenging responses, with the highest inhibition observed for the red beetroot formulation (8.94%). Overall, triterpenoid saponin-containing beetroot extracts modified the functional performance of the cleansing formulations, particularly their foaming and oil-emulsification properties. These findings support their potential as sustainable, plant-derived surfactant-supporting ingredients in multifunctional cleansing formulations.

The Content and Stocks of Organic Carbon and Labile Carbon Fractions Are Key Properties for the Sustainable Use of Terrestrialized Former Mill Ponds
(MDPI, 2026) Mendyk, Łukasz; Glina, Bartłomiej; Glatzel, Stephan; Markiewicz, Maciej; Sewerniak, Piotr; Ukalska-Jaruga, Aleksandra
The basins of former mill ponds are a common element of the cultural landscape, while soil science studies focusing on mill pond sediments remain relatively rare. One of the key properties relevant to the sustainable management of these sites is the content and stocks of organic carbon in the soils developed from the mill pond sediments. Therefore, the study aimed to analyze the total organic carbon (TOC) and total nitrogen content, as well as its stocks in the studied soils, the share of the labile fractions of these compounds in relation to the environmental factors influencing these properties and finally their potential changes over time (stability). The obtained results confirmed that the studied soils (mostly classified as Gleyic Fluvisols and Fluvic Phaeozems) are characterized by a high amount of TOC. This manifests in the large TOC stocks in the upper 50 cm (mean = 18.1; min = 8.35; max = 35.5 kg m−2) and in the whole soil profiles (mean = 43.7; min = 10.6; max = 93.6 in kg m−2). The dissolved organic carbon share in TOC content was slightly over 1% on average (mean = 1.06; min = 0.19; max = 4.75) and the specific UV absorbance averaged about 2.40 L mg C−1 m−1, indicating the relatively large proportion of recalcitrant organic fractions and low potential for further degradation.
Salinity-driven evolution of psychrotolerant Bacillus velezensis S_51 strain reveals metabolic adaptations to osmotic stress and enhanced glycine betaine production
(Springer Nature, BioMed Central (BMC), 2026) Goszcz, Aleksandra; Musiałowski, Marcin; Ciuchciński, Karol; Stasiuk, Robert; Błaziak, Kacper; Furtak, Karolina; Junkier, Aleksandra; Bernatowicz, Anna; Schiavon, Michela; Dębiec-Andrzejewska, Klaudia
Soil salinisation limits agricultural productivity by disrupting microbial homeostasis and plant–microbe interactions. Osmoprotectants, including glycine betaine, play a crucial role in protecting microbial cells against osmotic stress by stabilising cellular structures and maintaining osmotic balance. To optimise microbial production of glycine betaine, adaptive laboratory evolution (ALE) was applied to Bacillus velezensis S_51 under increasing sodium chloride (NaCl) concentrations, providing insight into the underlying metabolic and genomic adaptations. After 10 sequential passages (500 generations), the evolved strain exhibited an adaptive shift in growth preference towards higher salinity from 0% to 4% (0.68 M) NaCl, indicating niche specialisation. This adaptation was accompanied by a pronounced increase in osmoprotection, with intracellular glycine betaine levels rising by ~262-fold relative to the ancestral strain, reaching to 882.25 ± 68.58 µM g⁻¹ DM. Metabolic profiling revealed a non-uniform reorganisation of substrate utilisation, with differentiation between ancestral (P1) and evolved (P10) strains largely driven by a limited subset of compounds (~62% contribution of key substrates). The evolved strain showed a ~ 4–5-fold increase in the number of effectively utilised carbon (C) and nitrogen (N) sources, with selective enhancement of specific amino acids (e.g., L-serine, L-aspartic acid) and reduced utilisation of several carbohydrates and hexose phosphates, indicating redistribution of substrate utilisation profiles under osmotic constraints. Functional trait analysis showed increased biofilm formation and elevated indole-3-acetic acid (IAA) production (from 0.1 to 0.13 µg mL⁻¹), while siderophore production remained stable. Genomic analysis identified mutations in key regulatory genes, including kapB, spo0A, and comP, suggesting an association between phenotypic shifts and regulatory network reconfiguration. Together, these results demonstrate that ALE drives coordinated metabolic, physiological, and regulatory adaptation, enhancing microbial fitness under saline conditions and supporting its application in saline soil biotechnologies.
