“…Since the content of the main EO constituent palmitic acid does not exceed 20% and there are more than 10 other antimicrobially active compounds ranging from 1 to 8% it is difficult to suggest the main agents responsible for the E. rostkoviana EO antimicrobial effect. Palmitic acid has been previously identified as the major compound of fractions active against Gram-negative, but not Gram-positive, bacteria [ 24 ]. On the other hand, medium-chain saturated fatty acids and long-chain unsaturated fatty acids are known to inhibit especially Gram-positive bacteria [ 25 ].…”

Eyebright, Euphrasia rostkoviana Hayne (Scrophulariaceae), is a medicinal plant traditionally used in Europe for the treatment of various health disorders, especially as eyewash to treat eye ailments such as conjunctivitis and blepharitis that can be associated with bacterial infections. Some Euphrasia species have been previously reported to contain essential oil. However, the composition and bioactivity of E. rostkoviana oil are unknown. Therefore, in this study, we investigated the chemical composition and antimicrobial activity of the eyebright essential oil against some organisms associated with eye infections: Enterococcus faecalis, Escherichia coli, Klebsiella pneumoniae, Staphylococcus aureus, S. epidermidis, Pseudomonas aeruginosa, and Candida albicans. GC-MS analysis revealed more than 70 constituents, with n-hexadecanoic acid (18.47%) as the main constituent followed by thymol (7.97%), myristic acid (4.71%), linalool (4.65%), and anethole (4.09%). The essential oil showed antimicrobial effect against all organisms tested with the exception of P. aeruginosa. The best activity was observed against all Gram-positive bacteria tested with the minimum inhibitory concentrations of 512 µg/mL. This is the first report on the chemical composition of E. rostkoviana essential oil and its antimicrobial activity.

The interest in discovering and developing natural antimicrobials has significantly increased due to consumer preferences for foods that are free of chemical preservatives while still microbiologically safe. One of the best sources of natural antimicrobials is certain mushrooms (fungi) as many of them not only have nutraceutical functions but also possess antimicrobial properties. This article reviews the available information on mushroom antimicrobials for food safety control. It includes available resources, extraction procedures, antimicrobial activities, and the status of their applications to food safety. The review indicates that there are great potential benefits to be gained from mushroom antimicrobials in food production, processing, and preservation as a biosolution to meet the increasing demands for food quality and safety.

There is an urgent need to search for effective novel antibiotics due to the evolution of pathogen resistance towards the existing anti-microbial drugs. To fulfill the demand of pharmaceutical industries for novel drugs against pathogenic microbes, the potential source is nature, which is the largest repertoire for discovering biologically active drugs. Among the natural products, mushrooms are primary sources of diverse low and high-molecular-weight compounds that demonstrate anti-bacterial, anti-fungal, anti-parasitic and anti-viral activities. Mushrooms belonging to basidiomycetes or ascomycetes were classified into edible and non-edible and had high nutritive and medicinal properties due to the presence of bioactive compounds. The most common edible mushrooms comprise Agaricus bisporus, Lentinus, Auricularia. Hericium, Grifola, Flammulina, Pleurotus, and Tremella are potent sources of vitamins (thiamine, riboflavin, niacin, biotin and ascorbic acid, Vitamin A and D), lipids (mono, di, and triglycerides, sterols, phospholipids) and polysaccharides whereas non-edible mushrooms Ganoderma lucidum (Reishi), Lentinus edodes (Shiitake), Inonotus obliquus (Chaga), Ganoderma, Trametes, Cordyceps spp., etc., are potent sources of alkaloids, terpenoids, steroids, anthraquinones, benzoic acid derivatives, and quinolines. The literature review suggests that mushrooms showed high anti-microbial activities against Gram-positive bacteria (Bacillus spp., Listeria monocytogenes, Micrococcus spp., Staphylococcus spp. etc.) and Gram-negative bacterial species (Escherichia coli,Klebsiella spp. or Salmonella sp) as well as anti-fungal (Candida spp., Aspergillus spp., Penicillium spp. etc.) and anti-viral (HIV-I, influenza) activities. The present chapter highlighted the mushrooms showing anti-microbial activity, techniques for appraisal of anti-microbial activity, anti-microbial bioactive compounds and last but not least, the downstream process of some selected compounds originally isolated from mushrooms.
