  Enterococcus gallinarum CRL 1826 isolated from an American bullfrog (Lithobates catesbeianus) skin inhibits the growth of Citrobacter freundii, Pseudomonas aeruginosa (bullfrog pathogens) and Listeria monocytogenes by a synergistic effect between organic acids and a bacteriocin-like molecule. This bacteriocin, named enterocin CRL 1826, showed a proteinaceous nature, heat stability and polar characteristics. Its production followed kinetics of primary metabolites synthesis reaching a maximum of 61,400 AU/mL. The minimum inhibitory and minimum bactericidal concentrations were 2,640 and 5,280 AU/mL, respectively, against L. monocytogenes. The addition of 120,000 AU/mL of enterocin to growing L. monocytogenes and Gram-negative (P. aeruginosa and C. freundii) bacteria showed bactericidal an.. Read More»
