Antimicrobial effects of fatty acid fructose esters

Abstract

Karlová T., Poláková L., Šmidrkal J., Filip V. (2010): Antimicrobial effects of fatty acid fructose esters. Czech J. Food Sci., 28: 146-149.Antimicrobial effects of various fatty acids and their esters have been extensively studied. Esters with saccharides (glucose, sucrose) have been found to have a broad spectrum of microbicidal activity. The objective of this study was to investigate the susceptibility of four microbial strains (Bacillus cereus, Escherichia coli, Saccharomyces cerevisiae, and Fusarium culmorum) to the antimicrobial properties of fatty acid (capric, lauric, myristic, and palmitic) fructose esters. Microorganisms were cultivated in liquid media supplemented with various concentrations of the tested agents. A spectrophotometric method was used for the quantitative detection of the microbial growth. Both the cultivation and measuring of the absorbance was carried out in microtiter plates. Our results indicate that the addition of the tested compounds strongly reduce the number of viable microorganisms. Higher concentrations caused microbicidal effect. The inhibitory action decreased rapidly as the chain length increased. Caprinoylfructose proved to be the most active.

Antimicrobial properties of 11-cyclohexylundecanoic acid

“…The curves of the dependence of the absorbance on time (72 h -bacteria, 240 h -yeast and mould) represent the data output. Detailed methodology is described in a previous paper (Karlová et al 2010). …”

Susceptibility of Escherichia coli and Clostridium perfringens to sucrose monoesters of capric and lauric acid

“…These biodegradable nonionic surfactants can also be applied as emulsifiers for foodstuff, personal care products, and medical supplies (Fietcher 1992;Yan et al 1999;Godshall 2001;Polat and Linhardt 2001). Antibacterial effects of fatty acids and their derivatives were observed in connection with Listeria monocytogenes (Monk et al 1996;Nobmann et al 2009), Staphylococcus aureus (Monk et al 1996;Nobmann et al 2010), Bacillus cereus , Escherichia coli (Smith et al 2008;Karlova et al 2010), and various food spoilage microorganisms (Yang et al 2003;Nobmann et al 2009;Polakova et al 2010). Contrary to the evaluation of the effect of free fatty acids or their monoglycerides studied extensively in the past (anticlostridial effect observed for example by Timbermont et al 2010), no study on the effect of sucrose monolaurate on Clostridium perfringens has been conducted.…”

“…Microorganisms differ in their susceptibility to carbohydrate fatty acid derivatives, and Grampositive bacteria were found to be more susceptible than Gram-negatives (Smith et al 2008;Nobmann et al 2009;Karlova et al 2010). The antimicrobial activity of carbohydrate fatty acid derivatives depends on both the carbohydrate moiety (Smith et al 2008;Nobmann et al 2009) and the carbon chain length (Smith et al 2008;Polakova et al 2010).…”

Daya Antimikrobia Sarang Lebah Madu Trigona spp terhadap Mikrobia Patogen

“…Senyawa lauric acid dan myristic acid dalam kantong telur dan oleic acid yang terdapat dalam sarang lebah madu Trigona spp merupakan antibakteri untuk menghambat pertumbuhan bakteri gram positif seperti Staphylococcus aureus (Batovska et al, 2009;Desbois et al, 2013). Senyawa decanoic acid (capric) dan asam palmitat yang terdapat dalam semua bagian sarang lebah madu Trigona spp serta lauric acid dan myristic acid dalam kantong telur merupakan agen antifungi yang dapat menghambat pertumbuhan Candida albicans, bakteri Gram positif dan bakteri Gram negatif (Pohl et al, 2011;Karlova et al, 2010;Karbara et al, 1972). Heptadecen-8-carbonic acid dalam kantong polen memiliki kemampuan sebagai agen antimikrobia.…”
