Isolation and characterization of quinoa antimicrobial peptides and its effect on the microbial diversity of fresh apple juice.
Food Chem
December 2024
Xinjiang Key Laboratory of Biological Resources and Genetic Engineering, College of Life Science and Technology, Xinjiang University, Urumqi 830017, China. Electronic address:
This study developed antimicrobial peptides (AMPs) from quinoa with high antibacterial activity and stability by mixed-bacteria fermentation. Furthermore, among 9 peptide fractions purified by membrane separation and chromatography, F1 could effectively inhibit the growth and propagation of bacterial microorganisms in apple juice. Subsequently, F1 identified LC-MS/MS as 95 peptides, molecular weights 494.

Key Laboratory of Microbial Pesticides (Ministry of Agriculture and Rural Affairs), National Biopesticide Engineering Research Centre, Hubei Biopesticide Engineering Research Centre, Hubei Academy of Agricultural Sciences, Wuhan 430064, China.
This study investigates a novel antimicrobial peptide AtR905 derived from the endophytic fungus , which was successfully expressed in , purified, and characterized, and highlighted as a promising potential biocontrol agent against various plant pathogens. The results indicated AtR905 exhibited broad-spectrum antimicrobial activities against key pathogens such as and with very low minimal inhibitory concentrations (MICs). Stability tests confirmed that AtR905 retains its antimicrobial properties under varying thermal, pH, and UV conditions.

Department of Medical Microbiology, Faculty of Medicine, University of Debrecen, Nagyerdei Krt. 98., Debrecen, 4032, Hungary.
The sudden emergence of multidrug- and pan-resistant Candida auris isolates, combined with limited treatment options, poses significant global challenges in healthcare settings. Combination based therapies are promising alternative options to overcome C. auris related infections, where echinocandin and isavuconazole (ISA) combinations may be an interesting and promising approach.

Faculty of Medicine and Medical Sciences, University of Balamand, Kalhat, Tripoli P.O. Box 100, Lebanon.
Cyanobacteria, also known as blue-green algae, are a diverse phylum of photosynthetic, Gram-negative bacteria and one of the largest microbial taxa. These organisms produce cyanotoxins, which are secondary metabolites that can have significant impacts on both human health and the environment. While toxins like Microcystins and Cylindrospermopsins are well-documented and have been extensively studied, other cyanotoxins, including those produced by and , remain underexplored.

Membranes (Basel)
December 2024
School of Marine Science and Technology, Harbin Institute of Technology at Weihai, Weihai 264209, China.
The issue of environmental pollution caused by wastewater discharge from fruit juice production has attracted increasing attention. However, the cost-effectiveness of conventional treatment technology remains insufficient. In this study, a gravity-driven membrane bioreactor (GDMBR) was developed to treat real fruit juice wastewater from secondary sedimentation at pressures ranging from 0.
