Abstract
In the current study, sodalite was prepared from natural material (Um Had feldspar), Quseir area, Red Sea, Egypt via hydrothermal processes. It was modified by adding (Ca, Mg, Fe and Zn) ions to improve their antimicrobial properties. The prepared and modified samples were examined using Fourier-Transform Infrared (FT-IR), X-ray diffraction (XRD), surface area, and scanning electron microscopy (SEM). The sodalite composites were applied to study their antimicrobial effects on different human foodborne pathogenic bacteria (five strains) and food spoilage yeasts (seven strains). The inhibition zone's diameter for the composite samples against pathogenic bacteria, it turns out Zn-sodalite was the best one against the Gram-positive bacteria Staphylococcus and the Gram-negative bacteria Escherichia coli and Salmonella sp., while Ca-sodalite works better against the Gram-positive bacteria Bacillus cereus. Mg-sodalite and Ca-sodalite were recorded the highest inhibition zone 14±2 against Listeria monocytogenes while Fe-sodalite is the lowest one against all pathogenic bacteria. Concerning the pathogenic yeasts, Zn-sodalite with its different concentrations possessed the highest antifungal activity against Candida parapsilosis AUMC 10217 giving inhibition zone diameter ranging from 19±0.71 to 23±0.82 mm, followed by Fe-sodalite, while Ca-sodalite and Mg-sodalite exhibited the lowest effect. Fe-sodalite gave a powerful effect on Candida albicans AUMC 10216 followed by Zn-sodalite (10:90%). Fe-sodalite and Mg-sodalite had a weak antifungal effect on the yeast Rhodotorula mucilaginosa AUMC 10731. The study demonstrates that sodalite composites are promising sustainable, cost effective and eco-friendly alternative antimicrobial agents.
