摘要

Egg contamination with microbial pathogens is an enduring worldwide concern. Natural products are frequently recommended as ideal alternatives to substitute synthetic and chemical antimicrobials. Oak galls (Quercus infectoria) are aberrant growths on oak trees that have many medicinal and pharmaceutical applications.Q. infectoriaextract (QIE) antimicrobial action was assessed against many microbial species, and used for eggshell decontamination. QIE antimicrobial activity was evidenced againstStaphylococcus aureus,Escherichia coli,Pseudomonas aeruginosa,SalmonellaTyphimurium andCandida albicans, using different assay methods. Disinfection of eggshell microbial contamination, by immersion in 1% QIE solution, sharply reduced total colony count, yeasts and molds,Enterobacteriaceae.E. coliandS. aureuswere completely inhibited after 60min of immersion in QIE. QIE biochemical analysis revealed elevated contents of phenolic and flavonoid compounds. The captured micrographs ofS. aureuscells treated with QIE showed strong alterations in cell morphology; cells were entirely lysed and ruptured after 6h of treatment. QIE can be recommended as an effective and natural disinfectant for decontaminating eggshells from pathogenic microorganisms.
