This study demonstrates a simple one-pot green method for biosynthesis of terpenoids encapsulated copper oxide nanoparticles (CuONPs) using aqueous leaf extract of Eucalyptus globulus (ELE), as reducing, dispersing, and stabilizing agent. Indeed, the greater attachment and internalization of ELE-CuONPs in Gram-positive and -negative biofilm producing clinical bacterial isolates validated the hypothesis that terpenoids encapsulated CuONPs are more stable and effective antibacterial and antibiofilm agent vis-à-vis commercially available nano and micro sized analogues. Gas chromatography-mass spectroscopy (GC–MS)...

(Natural News) Traveling to outer space is a pretty tough gig for astronauts trying to stay healthy, as shuttling back and forth to places like Mars and the Moon significantly increases one’s risk of developing infections from antibiotic-resistant “superbugs,” experts claim. Not only is there a higher risk of contracting bugs like MRSA (methicillin-resistant Staphylococcus...

Publication date: Available online 20 March 2019Source: Journal of Hazardous MaterialsAuthor(s): Soyoung Baek, Sung Hee Joo, Michal ToborekAbstractTreating multidrug-resistant bacteria has been a challenging task, although the bacteria have been reported as a trace contaminant present in tap water. Given emerging issues on antibiotic-resistant bacteria, the present study investigated a novel treatment method in which ZnO nanoparticles (NPs) are encapsulated in an alginate biopolymer solution to explore primary antibacterial mechanisms. The antibacterial effects of this technology on two model antibiotic-resistant bacteria ...

oacute;n JJ, Webster TJ Abstract The green synthesis of biomaterials is of significant interest as it enables the safe and sustainable preparation of noble metallic nanoparticles for medical applications. Microalgae polysaccharides have received attention due to their outstanding properties such as biocompatibility, biodegradability and low cost. In addition, due to their variety of remarkable biological and physicochemical properties, polysaccharide-based nanoparticles have advantageous features yet to be explored. The primary objective of the current research was to investigate exopolysaccharides isolated from g...

In this study, after minimal inhibitory concentrations (MICs) and minimal bactericidal concentrations (MBCs) of sole tannic acid and β-lactam were investigated for each isolate, the synergistic activities of β-lactams combined with tannic acid against one MRSA ATCC 43300 and four MRSA clinical isolates were investigated with the concentrations starting at four fold of MICs of sole treatments of tannic acid and β-lactam by using checkerboard assay. To investigate sole and combination activities of tannic acid an d β-lactams, MIC and MBCs were observed. Results of this study showed that the activities of ...

This study isolated bacteria from the intestine of Sagor catfish (Hexanematichthys sagor) and screened it for antagonistic properties. Five out of 334 bacterial isolates inhibited growth of fish pathogens. The 5 bacterial strains included relatives of Shewanella haliotis, Myroides odoratimimus, Vibrio harveyi, Vibrio alginolyticus and Alcaligenes faecalis. The growth profiles and probiotic properties of these bacteria were examined. The results showed that the isolate 9 (3) 7.5.2.1, whose closest relative was S. haliotis exhibited growth and probiotic advantage compared to the other bacterial strains, such as highest doubl...
