Chlorpyrifos degradation and its impacts on phosphorus bioavailability in microplastic-contaminated soil
This study explores the degradation pathways of CPF (6 mg kg-1, 12 mg kg-1 of CPF addition) in soils with different levels of polylactic acid MPs (PLA-MPs) (0.0 %, 0.1 %, 0.5 %, 1.0 % w/w), and analyzes soil P fractions and phosphatase enzyme activities to investigate soil P bioavailability under different treatments. Results show that the degradation of CPF fits to a first-order decay model, with half-lives (DT50) ranging from 11.0 to 14.8 d depending on PLA-MPs treatment. The concentration of its metabolite 3, 5, 6-trichloropyridine 2-phenol (TCP) reached a peak of 0.93-1.67 mg kg-1 within 7-14 days. Similarly, the degra...

Phosphate Recovery from Urban Sewage by the Biofilm Sequencing Batch Reactor Process: Key Factors in Biofilm Formation and Related Mechanisms
Environ Res. 2024 Apr 23:118985. doi: 10.1016/j.envres.2024.118985. Online ahead of print.ABSTRACTThe biofilm sequencing batch reactor (BSBR) technique has been deployed in the laboratory to enrich phosphorus from simulated wastewater, but it is still not clear what its performance will be when real world sewage is used. In this work, the effluent from the multi-stage anoxic-oxic (AO) activated sludge process at a sewage plant was used as the feed water for a BSBR pilot system, which had three reactors operating at different levels of dissolved oxygen (DO). The phosphorus adsorption and release, the biofilm growth, and the...

Sphingomonas lacusdianchii sp. nov., an attached bacterium inhibited by metabolites from its symbiotic cyanobacterium
This study provided new ideas to understand the interactions between Microcystis and its attached bacteria. KEY POINTS: • A novel bacterium (JXJCY 53 T) was isolated from the cyanosphere of Microcystis sp. FACHB-905 (MF-905) • JXJCY 53 T modulated the growth and microcystin production of MF-905 • MF-905 could control the attached bacteria by specific chemicals other than microcystins (MCs).PMID:38661971 | PMC:PMC11045571 | DOI:10.1007/s00253-024-13081-x (Source: Applied Microbiology and Biotechnology)

Genetic Prediction of Micronutrient Levels and the Risk of Colorectal Polyps: A Mendelian Randomization Study
Previous epidemiological and experimental studies have yielded conflicting results regarding the influence of human micronutrient levels on the risk of colorectal polyps (CP). In our study, we conducted a two-sample Mendelian randomization (MR) investigation to probe the link between 13 human micronutrients (calcium, selenium, magnesium, phosphorus, folate, vitamins B-6, B-12, C, D, beta-carotene, iron, zinc, and copper) and the genetic susceptibility to CP.

PINK: a tender X-ray beamline for X-ray emission spectroscopy
A high-flux beamline optimized for non-resonant X-ray emission spectroscopy (XES) in the tender X-ray energy range has been constructed at the BESSY II synchrotron source. The beamline utilizes a cryogenically cooled undulator that provides X-rays over the energy range 2.1 keV to 9.5 keV. This energy range provides access to XES [and in the future X-ray absorption spectroscopy (XAS)] studies of transition metals ranging from Ti to Cu (K α , K β lines) and Zr to Ag (L α , L β ), as well as light elements including P, S, Cl, K and Ca (K α , K β ). The beamline can be operated in two modes. In PINK m...

Recalcification stabilizes cadmium but magnifies phosphorus limitation in wastewater-irrigated calcareous soil
In this study, we selected calcareous agricultural soil irrigated with wastewater for over 50 years to examine the recalcification effects of sugar beet factory lime (SBFL) at doses of 0%, 2.5%, 5%, and 10%. We found that SBFL promoted Cd transformation in the soil from active exchangeable species to more stable carbonate-bonded and residual species, which the X-ray diffraction patterns also confirmed results that CdSO4 reduced while CdS and CaCdCO3 increased. Correspondingly, the soil bioavailable Cd concentration was significantly reduced by 65.6-84.7%. The Cd concentrations in maize roots and shoots were significantly r...

Toxicology. 2024 Apr 21:153810. doi: 10.1016/j.tox.2024.153810. Online ahead of print.ABSTRACTBlack phosphorus (BP) is a new type of nanomaterial, which has been widely used in many biomedical fields due to its superior properties, but there are few studies on the toxicity of BP, especially in the reproductive system. To explore the effects of BP exposure on reproduction and reveal its molecular mechanism, we firstly investigated the potential toxicity of black phosphorus nanoparticles (BPNPs) in vivo. The results showed that BP exposure in pregnant mice can reduce the weight of fetal mice and placenta. H&E staining fu...
