The relationship between cellular protein content and selenium accumulation in freshwater microalgae

open access: yesIntegrated Environmental Assessment and Management, EarlyView.
Abstract Variability in the bioconcentration of selenium (Se) by primary producers at the base of the food web results in uncertainty in predictions of bioaccumulation and ecological risk to higher trophic level organisms. Water chemistry, speciation of Se, and periphyton community composition have all been suggested as factors that contribute to ...

The gut microbiome promotes the growth performance of black soldier fly larvae by detoxifying uric acid

open access: yesiMetaOmics, EarlyView.
This study demonstrates the detrimental effects of exogenous uric acid (UA) on the growth of black soldier fly (BSF) larvae, highlighting the role of gut microbiota in UA degradation. We isolated UA‐degrading bacterial strains associated with BSF, including Enterococcus faecalis AHAU24.

Host‐driven hepatic conversion of gut microbiota‐derived putrescine to spermidine mediates mannose's protective effects against hepatic steatosis in zebrafish

open access: yesiMeta, EarlyView.
Evidence for liver metabolism of gut‐derived microbial compounds into beneficial secondary metabolites has been lacking. Here, we demonstrate that Cetobacterium somerae (C. somerae), enriched by mannose supplementation under high‐fat diet conditions, convert arginine into putrescine.

Acute and Chronic Toxicity of Sediments Containing Platinum and Palladium on Freshwater Benthic Organisms Chironomus riparius and Hyalella azteca

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT The expanding demand for platinum group elements (PGEs) in industrial and medical applications has led to their increasing accumulation in aquatic sediments. However, their ecological impacts remain poorly understood, particularly for sediment‐dwelling invertebrates. This study assessed the toxicity of platinum (Pt) and palladium (Pd) across a
