“…The extract of E. hierosolymitana was found to contain 1-octen-3-ol, which is a mushroom alcohol that has been shown to have strong antifungal and antibacterial activities against Gram-positive bacteria including S. aureus, Staphylococcus epidermidis, and Bacillus subtilis [25]. In the present study, the same metabolite was confirmed to be present in E. hierosolymitana and the anti-staphylococcal activity may result from the presence of this metabolite.…”

Introduction: Resistance against commonly used antibacterial agents has become a globally recognized threat to human health. Therefore, the development of new and effective antibacterial agents is necessary to treat infections caused by resistant bacterial strains; plants are a promising source of new agents to be tested. Methodology: The minimum inhibitory concentrations (MIC) of ethanolic extracts of Erodium gruinum, Euphorbia hierosolymitana, Logoecia cuminoides, and Tamarix tetragyna against 10 Gram-negative and 5 Gram-positive bacteria were determined using agar well diffusion and microtiter plate dilution methods, respectively. The phytochemical composition of the crude extracts of the plants was determined using HPLC. Results: Pseudomonas aeruginosa ATCC 27853, Klebsiella pneumoniae, Proteus mirabilis, and Acinetobacter baumannii were sensitive to E. gruinum and E. hierosolymitana extracts. P. aeruginosa ATCC 27853 and M. catarrhalis were sensitive to L. cuminoides extract. P. aeruginosa ATCC 27853, P. mirabilis, and K. pneumoniae were sensitive to T. tetragyna extracts. For Gram-positive bacteria, Staphylococcus aureus ATCC 33591 and ATCC 43300 were sensitive to E. gruinum and E. hierosolymitana extracts. S. aureus ATCC 43300 and ATCC 33591 and Group D Streptococcus were sensitive to T. tetragyna extract. All Gram-positive bacteria were completely resistant to the extract of L. cuminoides. The major phytochemical components of the plant extracts belonged to flavonoids, tannins, terpenes, quinones, phytosterols, phytoestrogens, carbohydrates, fatty acids, and coumarin. Conclusion: The study showed the potential of the development of antibacterial agents from these plants. Phytochemical analysis revealed compounds that are candidates for new antibacterial drugs.

Foodborne diseases are very frequent and can easily transmit from contaminated food and food handlers. Among the foodborne pathogens, strains of Staphylococcus aureus, Bacillus cereus, Listeria monocytogen and Clostridium are very important because of its presence in a wide range of foodstuffs. A total of 520 food samples were collected at Peshawar (50%) and Mardan (50%), Khyber Pakhtunkhwa, Pakistan, from April 2016 to March 2017. Isolates were cultured and discriminated by Gram stain, followed by biochemical identification, disk diffusion assay was performed using antibacterial and antifungal agents. Out of 520, only 122 (23.46%) samples were positive for various types of bacterial and fungal pathogens. Gram-positive bacteria was the predominant (70.49%) followed by fungal pathogens (26.23%) and Gram-negative bacterial pathogens (3.27%) among the total positive samples. Prominent bacterial samples were Staphylococcus aureus, Bacillus spp., Clostridium spp., Staphylococcus

“…1-octen-3-ol for instance is responsible for the characteristic mushroom-smell and is produced by a broad variety of fungi. It is known to attract insects (Kline et al, 2007), exhibit antibacterial and slight antifungal properties (Xiong et al, 2017) and inhibit the germination of plant seeds and the growth of seedlings (Hung et al, 2014). Although the effect of VOCs emitted by the ∆lox1 mutants and the wildtype on Arabidopsis root architecture and shoot weight was similar in our study, the mutants had an enhanced ability to induce systemic resistance against B. cinerea.…”

The Lipoxygenase Lox1 Is Involved in Light‐ and Injury-Response, Conidiation, and Volatile Organic Compound Biosynthesis in the Mycoparasitic Fungus Trichoderma atroviride

The necrotrophic mycoparasite Trichoderma atroviride is a biological pest control agent frequently applied in agriculture for the protection of plants against fungal phytopathogens. One of the main secondary metabolites produced by this fungus is 6-pentyl-α-pyrone (6-PP). 6-PP is an organic compound with antifungal and plant growth-promoting activities, whose biosynthesis was previously proposed to involve a lipoxygenase (Lox). In this study, we investigated the role of the single lipoxygenase-encoding gene lox1 encoded in the T. atroviride genome by targeted gene deletion. We found that light inhibits 6-PP biosynthesis but lox1 is dispensable for 6-PP production as well as for the ability of T. atroviride to parasitize and antagonize host fungi. However, we found Lox1 to be involved in T. atroviride conidiation in darkness, in injury-response, in the production of several metabolites, including oxylipins and volatile organic compounds, as well as in the induction of systemic resistance against the plant-pathogenic fungus Botrytis cinerea in Arabidopsis thaliana plants. Our findings give novel insights into the roles of a fungal Ile-group lipoxygenase and expand the understanding of a light-dependent role of these enzymes.
