Impact of salinity and time on structure and functional potential of wastewater treatment biofilms in intermittent sand bioreactors
This study aimed to identify the changes in the microbial community due to both salt and days of operation through 16s rRNA sequencing and KEGG functional predictions. Results showed that the overall community structure and diversity were distinct as wastewater salinity varied from 0%-1.3%. At 1.3% salinity Zoogloea, a common genus in wastewater treatment plants, was not present and Aequorovita, Thaura and Dokdonella became the dominant genera. Nitrosomonas, an important ammonia oxidizing bacteria, increased in abundance with days of operation but was not significantly impacted by an increase in salinity. This finding was ...

Polonium-210 in total diet: a case study from Kuwait
AbstractThe activity concentrations of210Po have been determined in the most consumed Kuwaiti diet components including water and beverages. The total210Po annual intake has been calculated and was around 97.5 ± 4.1 Bq y−1 with roughly equal contributions from fish and seafood, grains, beverages, and protein (20.5 ± 0.2, 18.7 ± 0.2, 18.1 ± 1.1, and 16.7 ± 1.0 Bq y−1 sequentially). The annual intake of210Po was estimated by taking into account the loss of210Po during the cooking of seafood, tea making, and the preparation of leafy vegetable samples. The annual committed effective dose due ...

Development of a highly sensitive aptamer-based electrochemical sensor for detecting saxitoxin based on K < sub > 3 < /sub > Fe(CN) < sub > 6 < /sub > regulated silver nanoparticles
In this study, we developed a novel aptamer-based electrochemical sensor (AECs) for the sensitive detection of STX based on a K3Fe(CN)6 regulated silver nanoparticles (Ag NPs) modified with aptamer. The AECs was constructed by immobilizing aptamer on Ag NPs surfaces. Under optimized conditions, the AECs showed a linear response towards STX in the range from 0.04 to 0.15 μM with the regression equation of Y = -8.0 + 233.7 X (R2 = 0.9956). The limit of detection (LOD) was calculated to be 1 nM (based on 3 N/S), which is significantly lower than the regulatory limits for STX in seafood. Moreover, the AECs showed excellent se...

The highly selective rhodol-based putrescine probe and visual sensors for on-site detection of putrescine in food spoilage
Talanta. 2023 Dec 28;270:125615. doi: 10.1016/j.talanta.2023.125615. Online ahead of print.ABSTRACTPutrescine (Butane-1,4-diamine) has been regarded as a vital marker of spoiling protein-rich foods, especially meat and seafood. The detection of putrescine in food is considered a convenient and powerful method for evaluating the degree of spoilage of protein-rich foods. Herein, a novel rhodol-based fluorescent probe RSMA (formyl-rhodol Schiff base with methoxyaniline) was developed to detect putrescine. RSMA exhibited excellent linearity (R2 = 0.9912) in the concentration range of 0-45 μM of putrescine with a detection lim...

The Role of Supersulfide in Methylmercury Detoxification
Yakugaku Zasshi. 2024;144(1):41-45. doi: 10.1248/yakushi.23-00162-1.ABSTRACTMethylmercury is a ubiquitous neurotoxic substance present in the environment, and health concerns, especially through the consumption of seafood, remain. Glutathione (GSH)-mediated detoxification and the excretion of methylmercury are known metabolic detoxification pathways. We have also discovered a mechanism by which endogenous super-sulfides convert methylmercury to nontoxic metabolites such as bis-methylmercury sulfide. However, these metabolites are present in very small quantities, and the significance of the detoxification of methylmercury ...

Tracking antimicrobial resistance indicator genes in wild flatfish from the English Channel and the North Sea area: A one health concern
In conclusion, sul1 and intI1 genes emerge as robust indicators of AMR contamination in the marine environment, evident in seawater and species representing a benthic food web. Further studies are imperative to delineate marine species' role in accumulating and transmitting AMR to humans via seafood consumption. This research sheds light on the urgent need for a concerted effort in comprehending and mitigating AMR risks in marine ecosystems within the context of One Health.PMID:38160773 | DOI:10.1016/j.envpol.2023.123274 (Source: Environmental Pollution)
