Carbon–Phosphorus Limitation Is Associated With Shifts in Microbial Life‐History Strategies Across Vegetation Restoration Modes in Alpine Sandy Land on the Tibetan Plateau

Land Degradation &Development, EarlyView.
ABSTRACT Alpine sandy land on the Tibetan Plateau is fragile, with poorly developed soils, low nutrient availability, and weak biological resilience. Vegetation restoration is widely used to improve soil functioning, yet how microbial nutrient limitation and life‐history strategies vary among restoration modes remains unclear.

Honokiol as an α-glucosidase inhibitor

Frontiers in Pharmacology
Honokiol, a naturally occurring compound from Magnolia obovata Thunb., has many biological activities, but its anti-α-glucosidase activity is still unclear. Therefore, we determined its inhibitory effects against α-glucosidase.

Optimized Fertilization Balances Microbial Carbon and Nitrogen Use Efficiency: Evidence From Microbial Communities

Land Degradation &Development, EarlyView.
ABSTRACT Optimized fertilization involving reduced mineral N input and organic substitution can alter resource stoichiometry, microbial carbon use efficiency (CUE) and nitrogen use efficiency (NUE). However, how fertilization‐induced resource imbalance reshapes microbial community to regulate CUE and NUE remains unclear. We conducted a field experiment

Production of ß-glucosidase by Penicillium purpurogenum

, 2017
The fungus Penicillium purpurogenum was found to produce intracellular ß-glucosidase. Maximum activity of ß-glucosidase was observed on sucrose. Various cultural parameters of cultivation of P. purpurogenum for production of ß-glucosidase were optimized.

Biochar‐Induced Shifts in Resource Stoichiometry Shape Potential Nitrogen Limitation and Estimated Microbial Carbon Use Efficiency in Tropical Soils

Land Degradation &Development, EarlyView.
ABSTRACT Biochar is widely recognized as a promising amendment for enhancing soil carbon sequestration and microbial functioning, yet how biochar properties and application levels jointly influence potential microbial nutrient limitation and estimated microbial carbon use efficiency (CUE) remains unclear, especially in tropical farmland soils.

Improving Soil Health and Crop Yields Through Conservation Agriculture and Nutrient Management in Central India

Land Degradation &Development, EarlyView.
ABSTRACT Maintaining soil health and crop productivity in the semi‐arid Vertisols of central India poses a significant challenge under intensive agricultural practices. This 6‐year field study assessed the combined impact of different tillage methods, maize‐based crop rotations, and nitrogen management on soil's physical, chemical, and biological ...

Effect of Stand Density on Soil Microbial Carbon and Nitrogen Use Efficiency in Robinia pseudoacacia Plantations in the Loess Hilly‐Gully Region, China

Land Degradation &Development, EarlyView.
ABSTRACT Soil microbial carbon (CUE) and nitrogen (NUE) use efficiency are critical for soil carbon (C) sequestration and nitrogen (N) availability. However, how microbial CUE and NUE respond to stand density is unclear. Furthermore, it remains unclear whether the response of microbial CUE and NUE to stand density could be mediated by soil depth.

Storage treatment and diluent cause inconsistencies in commonly used fluorometric microplate enzyme assays conducted with saltmarsh soils

Limnology and Oceanography: Methods, EarlyView.
Abstract Fluorometric enzyme assays are a tool for determining potential enzyme activity in soils. A wide array of methodological approaches is adopted by different studies, making comparisons difficult. An important consideration is whether assay conditions replicate the environment of the samples or optimize potential enzyme activity.

Kigelia africana fruit fractions inhibit in vitro alpha-glucosidase activity: a potential natural alpha-glucosidase inhibitor

Background Diabetes affects 75% of people in low-income countries, where conventional drugs like metformin are available, but newer drugs like alpha-glucosidase inhibitors are not accessible to most Southern African patients.
