Summary: This study demonstrates that hand-made synthesized silver ultra nanoclusters are highly effective bactericides and anti-biofilm agents, eradicating biofilms at low concentrations. The researchers suggest that disrupting the chemical constitution of crosslinks may be a key mechanism in the antibacterial effects of the nanoparticles.

Summary: The study investigated the bactericidal effect of copper, silver, and chitosan nanoparticles against E. coli infection in broilers, and found that Ch-Ag NPs not only had the best antibacterial effects, but also acted as a growth promoter in broilers without leaving any residues in edible organs.

Summary: Bacterial motility can be a significant predictor of AgNP resistance, guiding the development of nanoenabled antimicrobials. The study of bacterial resistance to AgNPs is still in its early stages, with limited understanding of the underlying mechanisms. The resistance to subinhibitory concentrations of AgNPs in Escherichia coli K-12 MG1655 strain was found to be associated with a cusS mutation, potentially enhancing silver ion efflux and suggesting a role for flagellum-based motility in the resistance mechanism.

Summary: This study investigates the controlled release of antibacterial ions in phosphate-based coacervates (PC) gels. The results show that the gel can release antibacterial ions over time and significantly reduce bacterial growth. Biocompatibility studies also demonstrate an increase in cell viability when the gel is dissolved.

Summary: The emergence of carbapenem-resistant Escherichia coli poses a significant threat to public health. This study characterized 184 clinical strains of carbapenem-resistant E. coli and found differences in resistance patterns, resistance genes, plasmids, and sequence types. Silver nanoparticles showed efficacy against carbapenemase-positive E. coli.

Summary: Bacterial encapsulation is a novel biotechnological strategy for generating fuels and valuable chemicals. In this study, an optimal alginate encapsulated TiO2/Escherichia coli hybrid system was established to efficiently produce hydrogen under visible light. The encapsulated system exhibited enhanced hydrogen production even in the presence of oxygen.

Summary: A silver nanomaterial called Ag Nano Flowers (AgNFs) was developed as an effective drug carrier and adjuvant to restore drug susceptibility in multidrug-resistant bacteria. The combination therapy of AgNFs with antibiotics significantly reduced the doses of both compounds and eradicated drug-resistant bacteria by enhancing bacterial respiration and up-regulating the tricarboxylic acid cycle.

Summary: In this study, engineered Escherichia coli were used to improve the conversion of formate into hydrogen and carbon dioxide, while utilizing ethyl acetate production to overcome issues with by-product accumulation and low yields. High co-production yields exceeding 70% were achieved for both ethyl acetate and hydrogen, with in situ product removal via gas stripping proposed as an efficient technique.

Summary: Metal clusters, such as iron-sulfur clusters, play important roles in sustaining life and metalloprotein functions. In this study, the formation and crystal structure of a planar square tetranuclear silver cluster were reported when silver ions were mixed with human copper chaperone Atox1. Quantum chemical studies revealed that the tetranuclear silver cluster has an aromatic all-metal structure, representing the first observation of such structure in a protein.

Summary: This study explored the genetic engineering of Escherichia coli for hydrogen production. The introduction of exogenous hydrogenase and inactivation of endogenous hydrogenases resulted in both hydrogen production and uptake. Disabling the pathways for ethanol, lactate, and succinate production significantly increased hydrogen production. Unexpectedly, high expression of exogenous hydrogenase completely repressed hydrogen production, and the introduction of heterologous enzyme repressed the endogenous hydrogen production ability.

Summary: This study reports the green synthesis of silver nanoparticles using Eichhornia crassipes extract and evaluates its antimicrobial activity against Escherichia coli. The results show that the synthesized nanoparticles exhibit strong inhibitory effects against Escherichia coli after 120 minutes of reaction at 95 degrees Celsius. Further research is needed to investigate the appropriate synthesis parameters and concentration for the biomedical applications and antibacterial control systems.

Summary: The study found no viable culturable Escherichia coli in the meconium of healthy neonates, with E. coli colonization occurring postnatally rather than prenatally. E. coli colonization in neonates delivered vaginally occurred on the second day, possibly due to inoculation from the vaginal canal during delivery. The results suggest that the antimicrobial action in the prenatal colon's meconium may protect babies' gut from infection during delivery.
