Evolution of free amino acids and volatile compounds in dry‐cured fermented 'salchichón' sausages superficially inoculated with different molds

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Surface molds contribute to flavor development in dry‐cured fermented sausages through their effects on proteolysis, amino acid catabolism, and volatile compound formation. This study evaluated the influence of Aspergillus oryzae, Penicillium camemberti, Penicillium roqueforti and Penicillium nalgiovense on the evolution of free ...

Effects of Straw Incorporation and Tillage Depth on Soil Quality in Mollisol Profiles

Land Degradation &Development, EarlyView.
ABSTRACT Although improvements in soil quality under straw incorporation have been well documented, responses across soil profiles under different tillage depths remain unclear. To address this issue, a field experiment was established in 2011 in Mollisols with conventional tillage (20 cm depth) without straw (CT) and with straw (SCT), no tillage with ...

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.

Midgut proteases from larval spodoptera littoralis (lepidoptera: noctutoae) [PDF]

, 1992
The presence and properties of proteases present in larval midgut extracts from Spodoptera littoralis was investigated. Trypsin and chymotrypsin activities were found mainly in the midgut lumen while leucine aminopeptidase and dipeptidyl aminopeptidase ...

APRELIMINARY CHARACTERIZATION OF DIGESTIVE PROTEASE IN THE MID-GUT OF THE THIRD LARVAL INSTAR OF GASTEROPHILUS INTESTINALIS [PDF]

Veterinary Medical Journal - Giza, 2005
Protinases contained in the mid-gut of the early third instar of Gasterophilus intestinalis have been tentatively identified by midgut hydrolysis of synthetic substrates. Trypsin was identified by maximal hydrolysis of benzoyl-DL-arginine-p-nitroanilide (

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

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.

Effects of polystyrene nanoparticles on the microbiota and functional diversity of enzymes in soil

Environmental Sciences Europe, 2018
Background The increasing production of nanoplastics and the fragmentation of microplastics into smaller particles suggest a plausible yet unclear hazard in the natural environment, such as soil.

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.
