This study provided the first scientific evidence of T3SS prohibiting and antibacterial properties for the traditional knowledge in Myanmar of using plants as medicines for treating infections and gastrointestinal disease. Further researches are proposed to discover the active chemical compounds and mechanism of L. scandens (Roxb.) Buch.-Ham. ex Wight &Arn, M. nagi Thunb., T. citrina Roxb. ex Fleming, T. vulgaris L., and C. bejolghota (Buch.-Ham.) Sweet as antivirulence drugs and the potential of M. gagei J.R.Drumm and M. ferrea L. as new broad spectrum plant antibiotics. PMID: 30402120 [PubMed]

This study prepared antibacterial nanocomposite films for food packaging from Montmorillonite, which was modified by quaternary ammonium salts such as cetyltrimethylammonium bromide (CT), hexadecyl-tributyl phosphonium bromide (HD) and corn starch (CS). After this, it determined the antimicrobial activity of CS nanofilms against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) bacteria. Dispersion of silicate layers and starch nanocomposite films was analyzed by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM), and the results indicated that pre...

Because of the increasing concern about antibiotic resistant pathogen, photothermal therapy (PTT) as a new treatment strategy has received considerable attention. In this work, gold nanorods (GNRs) photoexcited by the near-infrared (NIR) light were immobilized on Ti surface by electrostatic surface self-assembly technique. Field emission scannin...

In this study, we successfully developed two novel antimicrobial peptides (AMPs), named crab-ALF2A and crab-ALF6A, which contain changes to the amino acid sequences of the lipopolysaccharide binding domain and signal peptide, respectively, of the ALF of the swimming crab Portunus trituberculatus. The crab-ALF2A peptide showed potent antimicrobial activity against the Gram-positive bacteria Bacillus cereus, Staphylococcus aureus, and Streptococcus iniae (minimal effective concentration [MEC] 1.51–1.93 μg/mL) and the Gram-negative bacteria Pseudomonas aeruginosa and Escherichia coli (MEC 1.87–1.98 μg/mL...

AbstractBioactive composite films were obtained by addingLactobacillus paracasei into a hydroxypropyl cellulose (HPC) ‐konjac flour (KF) matrix through a casting method. The mechanical, optical, and barrier properties were tested to determine the influence of the addition of lactobacilli into complex films. For purpose of evaluating the surface morphology of the composite films, scanning electron microscopy and a tomic force microscopy were carried out. Fourier transform infrared spectroscopy andX‐ray diffraction analyses were conducted to evaluate intermolecular interactions and crystallinity, respectively. Moreover, ...

In this study, 13 endophytic fungi strains were isolated from orchids, Dendrobium nobile, Dendrobium hibiki, and Oncidium altissimum. Two strains namely KDH5 and VDN3B were reported for the synthesis of SNPs by using 1 mM and 10 mM of silver nitrate solutions respectively. The present of SNOs was observed in wavelength ranging from 400 nm to 450 nm corresponding to the plasmon absorbance of SNPs. By applying various volume ratio of silver nitrate solution to fungal extracellular metabolites filtrate (FEMF), the UV-Vis spectrum showed an increasing trend of absorption intensity indicated that the concentration of SNPs synth...
