A purple non-sulfur bacterium producing polyhydroxybutyrate and the conserved region of pha synthase gene

open access: yesBioscience Journal, 2016
This study aimed to screen purple non-sulfur bacteria capable of accumulating granules or polyhydroxybutyrate (PHB) inside the cells, identify the potent strain, assay the enzyme or PHA synthase, and compare the PHB synthase gene with that of related ...

Revolutionising Agricultural Sustainability: New ‘Furrow Tillage’ can Mitigate Short‐Term Soil‐to‐Atmosphere CO2 Flux and Promote Soil‐Plant‐Microbe Health

open access: yesAdvanced Science, EarlyView.
Furrow tillage resolves the conventional‐vs.‐no‐tillage trade‐off by simultaneously cutting CO2 efflux to 2.0–3.0 g C m−2 d−1 and unlocking high nutrient availability for the rice rhizosphere. This scalable agronomic solution strengthens soil health, enhances plant physiology, reshapes microbial metabolism, and shifts paddy systems toward a net ...

Metatranscriptomic analysis of sulfur oxidation genes in the endosymbiont of Solemya velum

open access: yesFrontiers in Microbiology, 2011
Thioautotrophic endosymbionts in the Domain Bacteria mediate key sulfur transformations in marine reducing environments. However, the molecular pathways underlying symbiont metabolism and the extent to which these pathways are expressed in situ are ...

A Glucose Metabolism‐Modulatory Nanobiohybrid Vaccine Platform Promotes Anti‐Tumor Immunity by Orchestrating Autophagy‐Dependent Cross‐Presentation and H2S‐Enhanced NLRP3 Inflammasome Signaling

open access: yesAdvanced Science, EarlyView.
A nanobiohybrid vaccine was designed by constructing a hydrogen‐bonded organic framework coencapsulated with glucose oxidase (GOx) and tumor antigens. This nanobiohybrid vaccine executed a GOx‐catalyzed enzyme reaction that disrupted glucose metabolism and induced redox imbalance in dendritic cells, leading to autophagy‐dependent antigen cross ...

Soft Hypoxia‐Adaptive Bioelectronics Integrating PEDOT:PSS/Polydopamine/Enzyme Biocomposites for Closed‐Loop Therapeutics of Chronic Wounds

open access: yesAdvanced Science, EarlyView.
Hypoxia‐adaptive bioelectronics based on poly(3,4‐ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS)/polydopamine (PDA)/enzyme biocomposites couple O2‐centric biosensing with embedded O2 therapy to address oxygen‐deficient chronic wounds. Local O2 provision restores enzyme‐based metabolite sensing, while catalase‐mediated oxygen generation and

Discovery of an Antiviral Electron Transfer Process to Create Catalytically Self‐Sufficient Viral Restriction Factors

open access: yesAngewandte Chemie International Edition, EarlyView.
CYB5R3 is identified as a putative electron‐transfer partner of viperin (RSAD2), explaining why ER localisation is required for antiviral activity. Its utilisation enabled the engineering of immune‐silent, catalytically self‐sufficient antiviral restriction factor enzymes (iCAREs) that produce an antiviral nucleoside triphosphate analogue (ANTA ...

Mining Oral Probiotics Based on Their Pathogen Inhibition and Deodorization Roles

open access: yesFood Bioengineering, EarlyView.
A promising oral probiotic strain Streptococcus salivarius MY‐6 stood out from 41 candidate lactic acid bacteria through the high‐throughput strategy based on its inhibitions of the growth and biofilm formation of the main oral pathogens Fusobacterium nucleatum and Porphyromonas gingivalis, as well as its elimination of oral malodor‐associated ...
