Cover Story: Growing consumer demand for high-quality products coupled with minimally processed products and minor use of synthetic food additives have increased the need to search for new sources of natural antimicrobials to ensure product safety. This study aimed to evaluate the antimicrobial activity of extracts from the brown algae Ericaria selaginoides against Bacillus cereus in typical Catalan fresh cheese (“mató”) by means of testing. Three concentrations of a crude extract and its corresponding two subfractions (non-polar and mid-polar) obtained after purification showed an antimicrobial dose-dependent effect on B. cereus, from inhibition to inactivation. The results showed an improvement in the antimicrobial effect after purification compared with the effect observed when the crude extract was tested. Moreover, compounds of different chemical natures may be involved in this antimicrobial. View this paper
