Antimicrobial effects of fractions from cranberry products on the growth of seven pathogenic bacteria

Evaluation of phenolic-linked bioactives of camu-camu ( Myrciaria dubia Mc. Vaugh) for antihyperglycemia, antihypertension, antimicrobial properties and cellular rejuvenation

“…According to Caillet, Côté, Sylvain, and Lacroix (2012), cranberry phenolic compounds had significant inhibitory effects on S. aureus, Gram-positive bacteria where destabilization of cytoplasmic membrane, permeabilization of plasma membrane, inhibition of extracellular microbial enzymes and metal binding capacity could be reasons for the inhibition. Additionally, Silva et al (2014) and Souza et al (2014) reported that Gram-negative bacteria have more complex cell membranes (peptidoglycan, periplasm, and lipopolysaccharide) that making penetration difficult for antimicrobial agents.…”

“…The major phenolic compounds found in those powders were ellagic acid, quercetin, gallic acid, proanthocyanidins and anthocyanins (Fig. 2, Table 1), which might be responsible for antimicrobial activity against S. aureus (Caillet et al, 2012;Rauha et al, 2000;Saraiva et al, 2012). In this study, all analyzed phenolic compounds (ellagitannins, ellagic acid, syringic acid and myricetin) from Sao Paulo powders had better coefficient correlation with higher enzyme inhibition than for Amazonian powders (around 0.9 and 0.7, respectively Table 4).…”

Beyond celery and starter culture: Advances in natural/organic curing processes in the United States

“…Grapeseed (Vitis vinifera) extract, for example, has a high concentration of polyphenol compounds and has been reported to have significant anti-listerial properties (Anastasiadi, Chorianopoulos, Nychas, & Haroutounian, 2009;Bisha, Weinsetel, Brehm-Stecher, & Mendonca, 2010). Cranberry (Vaccinium macrocarpon) powder is also high in a variety of phenolic compounds that are significant inhibitors of both gram-positive and gram-negative bacteria including E. coli 0157:H7, L. monocytogenes, Salmonella typhimurium and S. aureus (Caillet, Côté, Sylvain, & Lacroix, 2012;Wu, Qiu, Bushway, & Harper, 2008;Xi, Sullivan, Jackson, Zhou, & Sebranek, 2011). While cranberry phenols have been found to be very effective antimicrobials, particularly for L. monocytogenes (Caillet et al, 2012), cranberry extracts and powders typically are quite acidic due to benzoic acid and other organic acids, and this may limit the amount that can be used in meat mixtures due to product quality effects (Xi et al, 2012).…”

Shiga Toxin-Producing E. coli and Ruminant Diets

“…Other researchers have found that the phenolic acids of lignin have antimicrobial activity against E. coli O157:H7 in fecal slurries, and feeding highly lignified forage to cattle showed a reduced period of E. coli O157:H7 shedding compared with those fed only corn silage (Wells et al, 2005). Several in vitro studies using various berry extracts have reported inhibition of E. coli O157:H7 growth (Caillet et al, 2012;Fullerton et al, 2011;Lacombe et al, 2012).…”
