Selected technology-critical elements as indicators of anthropogenic groundwater contamination
Environ Pollut. 2021 Apr 15;284:117156. doi: 10.1016/j.envpol.2021.117156. Online ahead of print.ABSTRACTGroundwater contamination originating from anthropogenic industrial activities is a global concern, adversely impacting health of living organisms and affecting natural ecosystems. Monitoring contamination in a complex groundwater system is often limited by sparse data and poor hydrogeological delineation, so that numerous indicators (organic, inorganic, isotopic) are frequently used simultaneously to reduce uncertainty. We suggest that selected Technology-Critical Elements (TCEs), which are usually found in very low co...

Legacy and emerging per- and polyfluoroalkyl substances (PFAS) in the Bohai Sea and its inflow rivers
In this study, the occurrence, distribution, sources, and risk of 29 legacy and emerging per- and polyfluoroalkyl substances (PFAS) in four kinds of environmental matrices in the Bohai Sea were investigated. The ∑PFAS concentrations were in the range of 0.40 ~ 61.4 ng/g dry weight (dw) in inflow river sediments, 0.48 ~ 61.4 ng/g dw in soil near river inflow, 0.37 ~ 4.18 ng/g dw in sea sediments, and 13.3 ~ 718 ng/L in seawater. PFAS with eight carbons accounted for > 62.2% by mass, in all samples. Perfluorooctanoic acid (PFOA) was the dominant PFAS both by mass and occurrence. Seawater from Laizhou Bay (south of the B...

Causal analysis of the temperature impact on deep-sea biodiversity
Biol Lett. 2021 Jul;17(7):20200666. doi: 10.1098/rsbl.2020.0666. Epub 2021 Jul 21.ABSTRACTThe deep sea comprises more than 90% of the ocean; therefore, understanding the controlling factors of biodiversity in the deep sea is of great importance for predicting future changes in the functioning of the ocean system. Consensus has recently been increasing on two plausible factors that have often been discussed as the drivers of deep-sea species richness in the contexts of the species-energy and physiological tolerance hypotheses: (i) seafloor particulate organic carbon (POC) derived from primary production in the euphotic zone...

Morphological and chemical classification of fine particles over the Yellow Sea during spring, 2015-2018
Environ Pollut. 2022 Apr 16:119286. doi: 10.1016/j.envpol.2022.119286. Online ahead of print.ABSTRACTAirborne fine particles can affect climate change and human health; moreover, they can be transported over significant distances. However, studies on characteristics of individual particles and their morphology, elemental composition, aging processes, and spatial distribution after long-range transport over the Yellow Sea are limited. Therefore, in this study, we conducted shipborne measurements of fine particulate matter of less than 2.5 μm in diameter (PM2.5) over the Yellow Sea and classified the individual particles in...

Critical Review of Biochemical Pathways to Transformation of Waste and Biomass into Bioenergy
Bioresour Technol. 2023 Jan 24:128679. doi: 10.1016/j.biortech.2023.128679. Online ahead of print.ABSTRACTIn recent years, biofuel or biogas have become the primary source of bio-energy, providing an alternative to conventionally used energy that can meet the growing energy demand for people all over the world while reducing greenhouse gas emissions. Enzyme hydrolysis in bioethanol production is a critical step in obtaining sugars fermented during the final fermentation process. More efficient enzymes are being researched to provide a more cost-effective technique during enzymatic hydrolysis. The exploitation of microbial ...

Niche differentiation of microbial community shapes vertical distribution of recalcitrant dissolved organic matter in deep-sea sediments
Environ Int. 2023 Jun 30;178:108080. doi: 10.1016/j.envint.2023.108080. Online ahead of print.ABSTRACTSedimentary organic matter provides carbon substrates and energy sources for microorganisms, which drive benthic biogeochemical processes and in turn modify the quantity and quality of dissolved organic matter (DOM). However, the molecular composition and distribution of DOM and its interactions with microbes in deep-sea sediments remain poorly understood. Here, molecular composition of DOM and its relationship with microbes were analyzed in samples collected from two sediment cores (∼40 cm below the sea floor), at depth...

Antimicrobial Activity of Lactobacillus Species Against Carbapenem-Resistant Enterobacteriaceae
Conclusion: Some Lactobacillus strains exhibit anti-CRE activity, which suggests potential applications for controlling or preventing CRE colonization or infection. Introduction Although Enterobacteriaceae are normal flora of the human intestinal system, they are also common pathogens causing human infections in the setting of both community-acquired and healthcare-associated infections (Hsueh et al., 2010; Toh et al., 2012; Lai et al., 2014; Jean et al., 2016). In this era of widespread antibiotic resistance, Enterobacteriaceae are no exception. Recently, the emergence of carbapenem-resistant Enterobacteriaceae (C...

Seasonal variability, long-term distribution (2001-2014), and risk assessment of polar organic micropollutants in the Baltic Sea
Environ Sci Pollut Res Int. 2021 Mar 23. doi: 10.1007/s11356-021-13254-5. Online ahead of print.ABSTRACTFrom 2001 to 2014, 13 surveys were conducted in the Baltic Sea, to determine its pollution of 50 micropollutants. The investigations focused mostly on the German western Baltic Sea; in 2008, one survey covered the entire Baltic Sea. Various groups of herbicides (such as triazines, phenoxyacetic acid, phenylurea), perfluoroalkyl substances, pharmaceuticals, and industrial products were analyzed during these surveys. The highest concentrations (median 1 to 4 ng/L) were observed for atrazine, simazine, chloridazone, 2,4-dic...
