Effects of replacing chemical fertilizer with organic fertilizer on organic carbon mineralization and carbon cycle functional genes in yellow soil

Scientific Reports
Fertilization-mediated soil organic carbon (SOC) mineralization is a key process in agroecosystem carbon cycling, yet the microbial mechanisms involved under different fertilization regimes remain unclear.

Polyethylene microplastics mineralize slowly in soil but integrate into soil structures and organic matter

Microplastics and Nanoplastics
Polyethylene is the most abundant microplastic in agricultural soils and can alter soil properties and plant health. However, microbial mineralization rates and the fate of polymer-derived carbon in soil remain poorly understood. We incubated UV-aged 13C-

The stoichiometry of soil microbial biomass determines metabolic quotient of nitrogen mineralization

Environmental Research Letters, 2020
Soil nitrogen (N) mineralization is crucial for the sustainability of available soil N and hence ecosystem productivity and functioning. Metabolic quotient of N mineralization ( Q _min ), which is defined as net soil N mineralization per unit of soil ...

Phosphorus availability and microbial immobilization in a Nitisol with the application of mineral and organo-mineral fertilizers [PDF]

Anais da Academia Brasileira de Ciências, 2015
ABSTRACT The aim of this study was to evaluate P availability, P and C contained in the microbial biomass, and enzymatic activity (acid phosphatases and β-glucosidases) in a Nitisol with the application of mineral and organo-mineral fertilizers. The experiment was performed in a protected environment with control over air temperature and soil moisture.

Gut Microbiota‐Isoallolithocholic Acid Crosstalk Promotes Calcium Oxalate Kidney Stone Formation via PARP1‐Mediated Parthanatos

Advanced Science, EarlyView.
ABSTRACT Bile acids have been implicated in calcium oxalate (CaOx) nephrolithiasis. Here, we employ multi‐omics approaches to identify isoallolithocholic acid (isoalloLCA) as the key bile acid elevated in the feces, serum, kidney, and urine of CaOx rats, confirmed by spatial metabolomics.

Microbial Mineral Weathering for Nutrient Acquisition Releases Arsenic [PDF]

Applied and Environmental Microbiology, 2009
ABSTRACT Tens of millions of people in Southeast Asia drink groundwater contaminated with naturally occurring arsenic. How arsenic is released from the sediment into the water remains poorly understood. Here, we show in laboratory experiments that phosphate-limited cells of Burkholderia fungorum mobilize ...

The Mitogen‐Activated Protein Kinase GhNTF3 Modulates the Arbuscular Mycorrhizal Symbiosis‐Immunity Trade‐Off in Cotton by Regulating Salicylic Acid Biosynthesis

Advanced Science, EarlyView.
AM symbiosis induces GhWAK13 to promote fungal colonization. GhNTF3 negatively regulates symbiosis by promoting SA biosynthesis. GhWAK13 sequesters GhNTF3 at the membrane, limiting its nuclear translocation and relieving SA‐mediated suppression. Under Verticillium stress, GhNTF3 enters the nucleus and interacts with GhJAZ6 to activate SA signaling ...
