Multifunctional alkyl ferulate esters as potential food additives: Antibacterial activity and mode of action against Listeria monocytogenes and its application on American sturgeon caviar preservation

Synergistic antibacterial and antibiofilm effects of ultrasound and MEL-A against methicillin-resistant Staphylococcus aureus

“…The morphological changes of MRSA were observed by scanning electron microscope (SEM) and transmission electron microscope (TEM) according to Shi et al [21] . Briefly, the bacterial cells of four groups (control, ultrasound treatment, MEL-A treatment, ultrasound and MEL-A treatment) were collected and fixed with 2.5% glutaraldehyde at 4 °C overnight.…”

Application of freeze-dried Yarrowia lipolytica biomass in the synthesis of lipophilic antioxidants

“…are a broadly studied issue, investigated most frequently for cinnamic acid and its phenolic derivatives. Shi et al ( 2018 , 2019 ) obtained six different esters of ferulic acid through lipase-catalyzed reactions. Of the compounds tested, hexyl ferulate proved to be the most active compound in inhibiting E. coli and Listeria monocytogenes growth.…”

“…Of the compounds tested, hexyl ferulate proved to be the most active compound in inhibiting E. coli and Listeria monocytogenes growth. Researchers showed that the examined ester was able to lyse cells, disrupt cell membranes, and also, affect the protein expression system, causing changes in membrane protein conformations and contents (Shi et al 2018 , 2019 ). Similarly, Merkl et al ( 2010 ) synthesized methyl, ethyl, propyl, and butyl esters of protocatechuic, gentisic, ferulic, caffeic, vanillic, and p -hydroxybenzoic acids, and then, antimicrobial activity was investigated.…”

“…Organic molecules, synthesized in mild conditions under sustainable chemical procedures, that preserve food and enlarge the availability of high-quality food, are undoubtedly desired products. Finally, compounds characterized by antimicrobial and antioxidant activity may enable the acquisition of safe food, free from food spoilage microorganisms, and free radicals that cause adverse changes in food (Shi et al 2018 , 2019 ). Importantly, enzymatic synthesis methods open new ways of producing valuable products under mild conditions in contrast to traditional chemical methods (Pradima et al 2017 ).…”

Antioxidant and Antibacterial Activity of Caprylic Acid Vanillyl Ester Produced by Lipase-Mediated Transesterification

“…Therefore, it is necessary to develop efficient antibacterial substances that inhibit the growth of these bacteria. Moreover, as the emergence of antibioticresistant bacteria has become a global issue, the development of a new type of natural antibiotics has become important [14][15][16][17][18]. Recently, various antibiotic substitutes have been screened from lipid materials that bacteria do not develop resistance [19].…”
