Summary: This study provides experimental evidence that thyme essential oil (TEO) has antifungal activity against fluconazole-resistant clinical isolates of C. albicans. TEO successfully inhibits the growth, germ tube formation, and budding of fungal pathogens at low doses, showing potential as an alternative to fluconazole for drug-resistant strains.

Summary: This study aimed to develop an antimicrobial food preservation material based on kaolin (KL) encapsulated with thyme essential oil (TEO). The release of TEO in the TEO/KL composite was controlled by the relative humidity inside of food packaging. The antimicrobial results illustrated that the activity of Escherichia coli (E. coli), Staphylococcus aureus (S. aureus) and Botrytis cinerea (B. cinerea) remarkably reduced after treating with the TEO/KL composite (1.0, 1.5 and 2.0 mg), and the inhibition rate reached over 99%. The cytotoxicity assays demonstrated good biocompatibility and biosafety of TEO/KL applied to food preservation. This composite also exhibited a desirable preservation effect on strawberries and grapes and displayed great potential in food industry.

Summary: Fifty percent of the world's population is infected with Helicobacter pylori, and alternative therapies are needed due to limited efficacy and adverse side effects of conventional eradication therapy. An essential oil mixture called HerbELICO (R), obtained from species from genera Satureja L., Origanum L., and Thymus L., was found to have potential in treating H. pylori infection. The main compounds in HerbELICO (R) were carvacrol and thymol.

Summary: This study assessed the effect of encapsulating thyme essential oil (TEO) into zein electrospun fiber film on extending the shelf life and preserving the quality of strawberries during storage. The findings showed that the zein/TEO fibers significantly decreased weight loss and maintained the anthocyanin content, firmness, and color of the strawberries. After 15 days of storage, the strawberries treated with zein/TEO fibers had higher scores for firmness, appearance, and sensory evaluation compared to the control.

Summary: Paraburkholderia phytofirmans PsJN is an endophytic bacterium that promotes plant growth and health. In this study, a gene bceQ related to EPS biosynthesis in PsJN was mutated, resulting in decreased EPS production and increased sensitivity to environmental stresses. The mutation also reduced the colonization of PsJN in plants under drought stress conditions. This is the first report to demonstrate the requirement of EPS production for maximal colonization of an endophytic bacterium in plant tissues under stress.

Summary: The study investigates the response of rice to different Burkholderia s.l. endophytes and finds that a non-native strain elicits a different response compared to native strains. The investigation also reveals that leaves exhibit a more conserved response to the endophytes than roots. Moreover, certain genes related to secondary metabolism, immunity, and phytohormones serve as markers for strain-specific responses.

Summary: This study analyzed the chemical composition of Thymus vulgaris L. (thyme) essential oil (TEO) and investigated the impact of a protective layer of amphiphilic oligochitosan (AOC) on the stability and transdermal potential of TEO multilayer nanoemulsions. The AOC layer improved the stability of TEO-based nanoemulsions and enhanced their anti-inflammatory, transdermal, and anti-melanoma effects.
