Copper nanoparticles (CuNPs) embedded in polyvinylpyrrolidone (PVP) and polyethylene oxide (PEO) fiber-matrices were prepared through centrifugal spinning of PVP/ethanol PEO/aqueous solutions, respectively. The prime focus the current study is to investigate antibacterial activity composite fibers against Escherichia coli (E. coli) Bacillus cereus (B. cereus) bacteria. During fiber formation, p...

The action of mustard gas on six animal, one plant, and two bacterial viruses; also on bacteria, yeast, and the pneumococcus-transforming principle has been studied. The viruses include Newcastle's disease of chickens, equine encephalomyelitis (Eastern strain), feline pneumonitis (Baker), rabbit papilloma (Shope), fixed rabies, rabbit myxoma, tobacco mosaic, T(2)r(+) phage of E. coli B, and a S...

Functionally graded epoxy composites with various concentration profiles of Fe3O4@TiO2 core–shell nanoparticles (NPs) were synthetized and characterized, with focus on their antibacterial properties. The NPs consisted of rutile, anatase, magnetite and hematite. Graded composites were produced starting with homogeneous 2 vol% to 12 vol% NPs suspensions using a magnetophorese process, leading to ...

1. The seven bacterial viruses of the T group active against E. coli, are rapidly inactivated at gas-liquid interfaces. 2. The kinetics of this inactivation whether brought about by shaking or by bubbling with nitrogen are those of a first order reaction. 3. This inactivation may be prevented by the addition of enough protein to maintain the gas-liquid interface in a saturated condition. 4. The...

1. Photodynamic therapy could be an alternative treatment for highly prevalent local antibiotic-resistant pathogens. 2. Photodynamic inactivation using toluidine blue O was observed on both reference strains and clinical samples, including methicillin-resistant Staphylococcus aureus, e x t e n d e d s p e c t r u m β l a c t a m a s e – p r o d u c i n g Escherichia coli and Klebsiella pneumoni...

Incorporation of black soldier fly larvae (BSFL) in fecal sludge management shows promise as a resource recovery strategy. BSFL efficiently convert organic waste into valuable lipids and protein, which can be further processed commercial products. Ensuring the microbial safety waste-derived products is critical to success resource-oriented sanitation requires development effective treatment. Th...
