Application of caffeine, 1,3,7-trimethylxanthine, to control Escherichia coli O157:H7

Behavior and changes in cell morphology ofEscherichia coliO157:H7 in liquid medium and skim milk in the presence of caffeine

“…Our results showed significant inhibition of tested strains in the presence of caffeine in both laboratory medium and in skim milk. These results are in agreement with those of Ibrahim et al (2006), who reported significant growth inhibition of E. coli O157:H7 with concentration levels of 0.50% and higher. The antimicrobial effect of Cf at 2.0 mg/mL against enterobacteria (E. coli and S. enterica) has been reported by Almeida et al (2006).…”

“…Plant products such as coffee and tea are the two non-alcoholic beverages consumed commonly all over the world and known to possess various biological properties including antibacterial activities (Arora, Kaur, & Kaur, 2009). Caffeine (1, 3, 7-trimethyl xanthine) is one of the three methylated xanthine alkaloid derivatives present in many plant species (Ibrahim, Salameh, Phetsomphou, Yang, & Seo, 2006) and has been shown to have antimicrobial activity against E. coli O157:H7, Salmonella, Pseudomonas sp., Staphylococcus aureus, and several strains of enterobacteria (Almeida,Farah,*Corresponding author.

“…Caffeine containing products such as coffee, tea, cola, and chocolates are among the most widely consumed foods. (Ibrahim et al, 2006). The antimicrobial activity of coffee and tea are accredited mainly to their polyphenolic contents (flavonoids, catechins, tannins) and caffeine (Arora et al, 2009).…”

The Plant Natural Products: Their Antioxidants, Free Radical Scavengers, DNA Protection and Antimicrobial Activities

“…Olive leaves extracts are rich in the phenolic compounds such caffeic acid, luteolin 7-Oglucoside, rutin, apigenin 7-O-glucoside and luteolin 4'-O-glucoside and have a strong antibacterial and antifungal activities [82,83]. Tea and coffee contains also different phenolic compounds with antimicrobial activity against some gram-positive and negative bacteria [84,85].…”
