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...

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...

Amomothrips Bhatti, a newly recorded genus of Thripinae from China (Thysanoptera: Thripidae)

Li, Yajin, Xie, Yonghui, Zhang, Hongrui, Li, Zhengyue (2018): Amomothrips Bhatti, a newly recorded genus of Thripinae from China (Thysanoptera: Thripidae). Zoological Systematics 43 (2): 211-214, DOI: 10.11865/zs.201819

Unraveling biochar’s role: dosage-dependent impacts on continuous-cropping soil microbiome and metabolites

Although biochar is a promising soil amendment for shaping soil microbial communities and modulating allelochemical levels in continuous cropping soils, its effects on the soil microbiome -particularly through benzoic acid metabolism in tobacco continuous cropping systems-remains...

Transcriptomic and metabolic basis of volatile compound dynamics in apricot fermentation

Abstract Here, we assessed the capacity of Wickerhamomyces anomalus LY13 to produce natural aroma compounds from apricot residue by combining time-resolved GC-MS profiling with RNA-Seq across five fermentation stages (0, 16, 32, 48, and 64 h). Without genetic engineering, W. anom...

Nicotine pharmacokinetics and abuse liability of commercially available tobacco products: an open-label, randomized, controlled study

This clinical study evaluated the abuse liability and nicotine pharmacokinetics of five tobacco products: conventional cigarettes, heated tobacco products (HTPs), e-cigarettes, snus, and tobacco-free nicotine pouches (NPs). In a controlled, randomized trial with adult smokers, we...

Residual-stress-driven deformation of thin-walled ring gears during hobbing

Thin-walled ring gears are prone to hobbing-induced distortion because material removal redistributes body residual stress (BRS) and introduces machining-induced residual stress (MIRS). This study distinguishes BRS and MIRS and establishes a coupled finite element method (FEM) wo...

Genomic and phenotypic characterization of phosphate-solubilizing strain YNK-FB0058, which potentially represents a novel species within the genus Phyllobacterium

Phosphate-solubilizing bacteria are soil-dwelling probiotics that promote plant growth and convert unavailable phosphorus into absorbable forms for plants. A phosphate-solubilizing strain, YNK-FB0058, which potentially represents a novel species within the genus Phyllobacterium ,...

Robust control of multi-joint robotic arm visual servoing based on neural network and adaptive command filtering

This paper proposes a multi joint robotic arm visual servo robust control strategy based on neural networks and daptive command filtering, aiming to solve dynamic uncertainty and nonlinear problems. By constructing an image plane feature point error model and deriving the image J...

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...
