Special Issue Information

Dear Colleagues,

Plants and marine organisms are extraordinary reservoirs of natural products with biological activity. In order to combat the remarkable increase in antibiotic resistance, it is necessary to find novel antimicrobials from natural sources that have intrinsic defense strategies. Lipids include a myriad of structures and the ability to adapt to environmental changes and protect plants and marine organisms from different environmental stresses. Several lipid classes obtained from these matrices have antimicrobial activity on different human pathogens. Free fatty acids have been the most studied compounds. However, the great world of lipids as antimicrobials is far from being fully explored. Thus, it is imperative to explore these endless sources of bioactive lipids, and to isolate, identify and characterize the compounds that exert the antimicrobial activity and to evaluate their in vitro and in vivo efficiency.

We kindly invite you to contribute with exciting and new research papers or state-of-the-art reviews on the antimicrobial activity of lipids from plant and/or marine origin. This issue aims at gathering the most recent work from researchers keen to demonstrate that lipids from natural sources are promising candidates as antibiotics and to boost new biotechnological applications of lipids in medicine, and in nutraceutical and pharmaceutical industries.

Active packaging incorporating antioxidants and antimicrobials is creating a niche in the market and becoming increasingly important. The main goal of this work was the design of bioactive bilayer films (zein/pullulan) incorporating licorice essential oil. The bilayer films were fully characterized in terms of their chemical, physical, barrier, antioxidant, and antimicrobial properties. Furthermore, the release kinetics of isopropyl palmitate, the major compound of the licorice essential oil, was evaluated by HPLC-DAD (high-performance liquid chromatography coupled to diode-array detector). Scanning Electron Microscopy (SEM) micrographs of cross-sections of the bilayer films clearly show the two layers of the films. Besides presenting the capacity to scavenge free radicals and to inhibit the lipid peroxidation, the developed bilayer films were also able to inhibit the growth of known foodborne pathogens (Enterococcus faecalis and Listeria monocytogenes). The release kinetics profile of isopropyl palmitate from bilayer films incorporating licorice essential oil demonstrated that in 50% ethanol at room temperature, the release was more effective, suggesting that the bilayer films will be more efficient if applied to package semi-fatty food.

In the actual post-antibiotic era, novel ways of rethinking antimicrobial research approaches are more urgent than ever. Natural compounds with antimicrobial activity such as fatty acids and monoacylglycerols have been investigated for decades. Additionally, the interest in other lipid classes as antimicrobial agents is rising. This review provides an overview on the research about plant and marine lipids with potential antimicrobial activity, the methods for obtaining and analyzing these compounds, with emphasis on lipidomics, and future perspectives for bioprospection and applications for antimicrobial lipids. Lipid extracts or lipids isolated from higher plants, algae or marine invertebrates are promising molecules to inactivate a wide spectrum of microorganisms. These lipids include a variety of chemical structures. Present and future challenges in the research of antimicrobial lipids from natural origin are related to the investment and optimization of the analytical workflow based on lipidomics tools, complementary to the bioassay-guided fractionation, to identify the active compound(s). Also, further work is needed regarding the study of their mechanism of action, the structure–activity relationship, the synergistic effect with conventional antibiotics, and the eventual development of resistance to lipids, which, as far as is known, is unlikely.
