Photocatalytically Activated Cu‐N1S3 Single‐Atom Nanozyme: Enhancing Enzyme Activities and Antibacterial Synergy for Highly Efficient Fruit Preservation

Advanced Science, EarlyView.
This study presents S‐coordinated Cu single‐atom nanozymes (Cu/CNS) fabricated via mild photocatalytic self‐assembly strategy. The nanozyme exhibits exceptional multi‐enzyme activity and near‐perfect antimicrobial efficacy. Incorporated into chitosan‐gelatin film, it enables pH‐responsive, broad‐spectrum fruit preservation, more than doubling the shelf‐

The Prevalence and Control of Bacillus and Related Spore-Forming Bacteria in the Dairy Industry [PDF]

, 2015
peer-reviewedMilk produced in udder cells is sterile but due to its high nutrient content, it can be a good growth substrate for contaminating bacteria. The quality of milk is monitored via somatic cell counts and total bacterial counts, with prescribed ...

GbWAKL20 Phosphorylates GbNFYB8 to Modulate Verticillium Wilt Resistance in Cotton

Advanced Science, EarlyView.
Wall‐associated receptor‐like kinases (WAKLs) play pivotal roles in extracellular–intracellular signal transduction. Upon sensing Verticillium dahliae infestation at the plasma membrane, GbWAKL20 accumulates and transmits signals to the nucleus via endoplasmic reticulum‐mediated Golgi vesicle transport.

Detection of Bacterial Endospores in Soil by Terbium Fluorescence

International Journal of Microbiology, 2011
Spore formation is a survival mechanism of microorganisms when facing unfavorable environmental conditions resulting in “dormant” states. We investigated the occurrence of bacterial endospores in soils from various locations including grasslands (pasture,

Surface appendages of bacterial spores [PDF]

Molecular Microbiology, 2006
SummaryBacilli and Clostridia generate dormant, highly resistant cells, called spores, in response to stress. Spores of many species are decorated by morphologically diverse structures of unknown function called appendages that have yet to be studied at the molecular level. In this issue, Walker et al. employ reverse genetics to identify genes encoding

Gut Bacterium Lysinibacillus Sphaericus Exacerbates Aspirin‐induced Intestinal Injury by Production of Carboxylesterase EstB

Advanced Science, EarlyView.
Schematic overview illustrating the detrimental role of gut microbiota in aspirin‐induced intestinal injury. L. sphaericus and its secreted carboxylesterase EstB are identified as key drivers that catalyze aspirin hydrolysis into salicylic acid, thereby exacerbating intestinal injury. Inhibition of EstB by the dietary compound flavanomarein effectively

Bacillus sphaericus mosquito pathogens in the aquatic environment

Memorias do Instituto Oswaldo Cruz, 1995
The fate of Bacillus sphaericus spores in the aquatic environment was investigated by suspending spores in dialysis bags in fresh and seawater. Spore viability was lost more rapidly in seawater. Neither B. sphaericus nor B. thuringiensis israelensis (B.t.

Systematic Engineering of Proteases in Saccharopolyspora Spinosa Reveals Synergistic Enhancement of Spinosad Biosynthesis via Substrate Flux Optimization

Advanced Science, EarlyView.
ARTP mutagenesis yielded Saccharopolyspora spinosa mutant D184 with improved extracellular nitrogen utilization. An integrated workflow of protease genetic manipulation, multi‐omics, and rational synergy design pinpointed a pepP‐clpP‐htpX synergistic triangular combination.

Emerging Applications of Bacterial Spores in Nanobiotechnology

Journal of Nanobiotechnology, 2003
Bacterial spores are robust and dormant life forms with formidable resistance properties, in part, attributable to the multiple layers of protein that encase the spore in a protective and flexible shield.
