Prospects for food applications of products from microorganisms

Antimicrobial activity and applications of fermentates from lactic acid bacteria – a review

“…Many reviews have been reported about metabolites' antimicrobial effect resulting from fermentation with lactic acid bacteria. 1,9,29–32 However, bacteriocins 33–35,37 and phenyllactic acid 6,36 stand out as antimicrobial agents of interest that could be present in fermented foods and fermentates. 27,38,39…”

“…Challenges in production and purication of selected metabolites: implications for food applications Many reviews have been reported about metabolites' antimicrobial effect resulting from fermentation with lactic acid bacteria. 1,9,[29][30][31][32] However, bacteriocins [33][34][35]37 and phenyllactic acid 6,36 stand out as antimicrobial agents of interest that could be present in fermented foods and fermentates. 27,38,39 Several reports isolate and test the antimicrobial activity of LAB and examine their potential as bacteriocins producers.…”

“…Fermentation is one of the fundamental technologies of modern industrial biotechnology that supports food, water, environment, energy, and medicine, among other applications. Microorganisms are utilised as microbial factories 1 to produce food ingredients at high yields with a lower environmental impact. Throughout the centuries, fermented foods and beverages have played a crucial role in the evolution of culinary traditions, offering abundant nutrients and advantages.…”

“…7 Cell-free supernatants (CFS) from lactic acid bacteria (LAB) have been widely studied as antimicrobials since they contain the metabolites derived from fermentation and/or secondary microbial products from metabolism. 1 CFS from several LAB have demonstrated their efficacy as antimicrobials against bacteria and fungi. 9 Depending on the fermentation medium used, CFS from lactic acid bacteria can be included in the food formulation, sprayed on the food's surface, and can also be used to coat the surface of the food 10 or incorporated into active packaging.…”
