Inhibition of toxicogenic Bacillus cereus in rice-based foods by enterocin AS-48

“…Enterocin AS-48 is a broad-spectrum cyclic antimicrobial peptide produced by E. faecalis and E. faecium strains (reviewed by Maqueda et al, 2004). This bacteriocin has been widely investigated in food systems against foodborne pathogenic bacteria such as L. monocytogenes, S. aureus, B. cereus, E. coli or S. enterica (Abriouel et al, 2010;Ananou et al, 2005;Cobo Molinos et al, 2005Grande et al, 2006Grande et al, , 2007aMartínez Viedma et al, 2008Muñoz et al, 2007). Partially-purified preparations of enterocin AS-48 can be produced easy on semi-synthetic media (Abriouel et al, 2003) and on whey-based substrates (Ananou et al, 2010), which makes this bacteriocin an amenable antimicrobial for application in foods.…”

“…In boiled rice and in a commercial infant rice-based gruel dissolved in whole milk artificially contaminated with a psychrotrophic enterotoxigenic strain of B. cereus cells, AS-48 addition caused complete bacterial inactivation and avoided enterotoxin production within a temperature range of 6-37°C [47] ( Table 4). Activity of AS-48 against B. cereus cells in rice gruel was potentiated by sodium lactate.…”

Bacteriocins are antimicrobial peptides produced by bacteria. Among them, the enterococcal bacteriocin (enterocin) AS-48 stands for its peculiar characteristics and broad-spectrum antimicrobial activity. AS-48 belongs to the class of circular bacteriocins and has been studied in depth in several aspects: peptide structure, genetic determinants, and mode of action. Recently, a wealth of knowledge has accumulated on the antibacterial activity of this bacteriocin against foodborne pathogenic and spoilage bacteria in food systems, especially in vegetable foods and drinks. This work provides a general overview on the results from tests carried out with AS-48 in different vegetable food categories (such as fruit juices, ciders, sport and energy drinks, fresh fruits and vegetables, pre-cooked ready to eat foods, canned vegetables, and bakery products). Depending on the food substrate, the bacteriocin has been tested alone or as part of hurdle technology, in combination with physico-chemical treatments (such as mild heat treatments or high-intensity pulsed electric fields) and other antimicrobial substances (such as essential oils, phenolic compounds, and chemical preservatives). Since the work carried out on bacteriocins in preservation of vegetable foods and drinks is much more limited compared to meat and dairy products, the results reported for AS-48 may open new possibilities in the field of bacteriocin applications.
