Physical, Volatile, and Flavour Precursor Changes in Faba Bean During Rhizopus oryzae Fermentation

Faba bean (Vicia faba L.) is increasingly recognised as a nutritious and sustainable food ingredient, although its characteristic beany and green odours can limit consumer acceptance. Fermentation offers a potential strategy to modify the sensory and functional properties of legu...

Multi-omics insights into linalool-mediated modulation of microbial metabolism during cigar tobacco solid-state fermentation

Mold contamination in solid-state fermentation (SSF) severely compromises product stability and safety, leading to spoilage and off-flavor formation. Although synthetic preservatives are used, they often induce ecological instability and residual risks, prompting a shift toward n...

Boosting Iturin A Production in Bacillus velezensis by Multimodule Engineering, Operon Restructuring, and Pickering Emulsion Fermentation

Abstract Iturin A is a valuable natural cyclic lipopeptide with broad application potential in multiple fields such as food preservation and agricultural production. However, its industrial production remains limited due to low fermentation yield. In this study, iturin A biosynth...

Transparent Ultraviolet-Shielding Poly(ester amide) Elastomers with Excellent Elastic Recovery via Hydrogen-Bonding Compensation

Abstract Developing sustainable elastomers that synergistically integrate intrinsic ultraviolet (UV) shielding, high elasticity, and optical transparency remains a fundamental challenge, as rigid chromophores essential for UV absorption inherently compromise network dynamics and...

Global Habitat Suitability and Distribution Shift Predictions of Myzus persicae Under Climate Change Based on an Optimized MaxEnt Model

Myzus persicae (Sulzer) is a globally important agricultural pest and a vector of numerous plant viruses. However, its potential global distribution under future climate change remains insufficiently quantified. In this study, we used 5531 occurrence records, six key bioclimatic...

Study on the influence of different heating modes on aerosol release stability of heated tobacco products

Abstract The puff-by-puff release stability of aerosols generated by heated tobacco products (HTPs) is a key factor influencing consumers’ sensory experience. This study systematically investigates the effects of different heating modes and the compatibility between heated tobacc...

NtNAC50–NtEXLB1 module enhances cadmium tolerance by strengthening root antioxidant defence and maintaining root structural homeostasis

Cadmium (Cd) contamination inhibits plant growth and threatens the safe production of crops, but the root-mediated regulatory mechanisms that simultaneously enhance Cd tolerance and reduce tissue Cd accumulation remain incompletely understood. This study aimed to determine the fu...

Mitigation of ammonia and nitrous oxide emissions and cutdown of composting cycle during Enteromorpha prolifera composting with the co-addition of attapulgite and biochar

Abstract Since 2007, annual blooms of the green macroalga Enteromorpha prolifera have occurred in China’s coastal waters, posing serious threats to local aquaculture and ecological environment. Composting is an ideal way for managing E. prolifera waste. This study explored how at...

Adsorption of the dinotefuran enantiomers by Mg‐modified peanut shell biochar: mechanism, site identification, and density functional theory validation

Abstract BACKGROUND The chiral pesticide dinotefuran, a neonicotinoid insecticide with high water solubility and persistence, poses significant ecological systems risks by interfering with the structure and functions of aquatic ecosystems and accumulating progressively through th...

Mechanistic Decoupling of the cis - and trans -Cleavage Activities of Cas12a via Phosphorothioate-Induced Kinetic Trapping

Abstract CRISPR-Cas12a is widely utilized for genome engineering and nucleic acid diagnostics, being distinguished by its indiscriminate single-stranded DNA (ssDNA) trans-cleavage activity triggered by its specific cis-target recognition. However, the precise kinetic coordination...
