Compostable and Recyclable Baroplastic Triblock Copolymers Enable Low‐Energy Polymer Processing

Small, EarlyView.
Baroplastic Poly(L‐lactide)‐block‐poly(ethylene glycol)‐block‐poly(L‐lactide) triblock copolymers enable ambient‐temperature processing under moderate pressure, reducing energy demand while preserving polymer integrity. The materials show rapid industrial compostability, effective chemical and physical recyclability, and compatibility with heat ...

Lysogeny in Leuconostocs

Nihon Chikusan Gakkaiho, 1980
Lactic streptococciおよびlactobacilliの溶原性についていくつかの報告が行われているが,leuconostoc菌種の溶原性についての報告は,著者らが知るかぎりにおいて見い出せない.本報告は,leuconostoc菌種の溶原性の検索を目的としleuconostoc 32菌株をマイトマイシンC処理により,その溶原性の有無を調べた.Leuconostoc菌株の溶原性のマイトマイシンCによる誘発は,その濃度に大きく依存しまたマイトマイシンCに対する感受性は,leuconostoc菌株によってことなった.Leuconostoc菌株を培養し対数期初期にマイトマイシンCを液体培地1ml当り最終濃度0.5μgおよび5.0μg加えて溶原菌株の誘発を行った.Leuconostoc ...

Large‐Scale Structural Dynamics in the Tail Fiber Modulate the Infective Transition of the T7 Bacteriophage

Small, EarlyView.
During host recognition, the fibers of T7 bacteriophages transition from a capsid bound state to an extended conformation, which requires some level of fiber flexibility. By using high‐speed atomic force microscopy, we show that the fibers have an internal molecular hinge and a torsionally compliant coiled‐coil region.

Temperate phage-antibiotic synergy across antibiotic classes reveals new mechanism for preventing lysogeny

mBio
A recent demonstration of synergy between a temperate phage and the antibiotic ciprofloxacin suggested a scalable approach to exploiting temperate phages in therapy, termed temperate phage-antibiotic synergy, which specifically interacted with the lysis ...

Characterization of the dynamic microbiome evolution across thrips species

Insect Science, EarlyView.
Comprehensive survey of the microbiome in thrips. The dominant bacterial genera found in thrips include intracellular ones, such as Wolbachia and Spiroplasma, and extracellular ones, including Serratia, Pantoea, and Acinetobacter. We isolated and sequenced high‐quality genomes of two dominant symbionts, Pantoea dispersa and Serratia marcescens.

Human Group A Streptococci Virulence Genes in Bovine Group C Streptococci

Emerging Infectious Diseases, 2010
Phage-encoded virulence genes of group A streptococci were detected in 10 (55.6%) of 18 isolates of group C streptococci that had caused bovine mastitis.

Effect of the microbiome on pathogen susceptibility across four Drosophilidae species

Insect Science, EarlyView.
Four Drosophilidae species were used to investigate how variation in the host microbiome influences susceptibility to infection. Microbial composition and abundance differed among species and treatments. The effects of microbiome manipulation on host survival were both species‐ and pathogen‐specific.

The tryptophan prenyltransferase ComQ from Bacillus subtilis 168 can prenylate daptomycin at Trp1

The FEBS Journal, EarlyView.
ComQ168 from Bacillus subtilis 168 catalyzes C‐terminal tryptophan farnesylation of ComX to generate a competence‐inducing pheromone. Recombinant ComQ168 also modifies cyclic peptides, including Daptomycin, likely at the N‐terminal tryptophan. Structural modeling highlights a C‐terminal binding region, supporting substrate promiscuity and establishing ...

Nitric Oxide Tunes Secreted Metabolite Bioactivity

Molecular Microbiology, EarlyView.
Pseudomonas aeruginosa produces phenazine metabolites that can react with nitric oxide (·NO) to form nitrosylated compounds. The formation of these metabolites results in rapid loss in P. aeruginosa viability and diminishes phenazine antimicrobial activity against other organisms, including Staphylococcus aureus. ABSTRACT The radical nitric oxide (·NO)

Protein STM3547 From Salmonella typhimurium Is a Phosphofructose Kinase B‐Type Enzyme With Ribose Kinase Activity

Molecular Microbiology, EarlyView.
The metabolism of ribose starts with the phosphorylation of its 5′ hydroxyl group. Salmonella typhimurium has two kinases that perform this function, namely ribose rinase (RbsK) and deoxyribose kinase (DeoK). Here we report a new ribose kinase that we named RikA. The illustration was partially created in BioRender.
