Bat white-nose syndrome, caused by the psychrophilic fungus Pseudogymnoascus destructans, has dramatically reduced the populations of many hibernating North American bat species. The search for effective biological control agents targeting P. destructans is of great importance. We report that the sesquiterpene trans, trans-farnesol, which is also a Candida albicans quorum sensing compound, prevented in vitro conidial germination for at least 14 days and inhibited growth of preexisting hyphae of five P. destructans isolates in filtered potato dextrose broth at 10 °C. Depending on the inoculation concentrations, both spore and hyphal inhibition occurred upon exposure to concentrations as low as 15-20 µM trans, trans-farnesol. In contrast, most North American Pseudogymnoascus isolates were more tolerant to the exposure of trans, trans-farnesol. Our results suggest that some Candida isolates may have the potential to inhibit the growth of P. destructans and that the sesquiterpene trans, trans-farnesol has the potential to be utilized as a biological control agent.

The isomerization of substituted allylic alcohols, including α-vinyl benzyl alcohol, -1,3-diphenyl-2-propen-1-ol, cinnamyl alcohol, coniferyl alcohol, 4-nitrocinnamyl alcohol, farnesol, 1,5-hexadien-3,4-diol, (1)-(-)-myrtenol and ,-(-)-carveol, catalyzed by the [RuCp(OH)(PTA)](CFSO) (1) and [RuCp(OH)(mPTA)](CFSO) (2) (PTA = 1,3,5-triaza-7-phosphaadamantane, mPTA = -methyl-1,3,5-triaza-7-phosphaadamantane) complexes was examined in pure water and water-containing media. The isomerization of the chalcone -1,3-diphenyl-2-propen-1-ol catalyzed by 1 to produce the natural product propiophenone displays the highest known turnover number for this reaction to date (TON = 200 and TOF = 40 h). A study delving into the catalytic reaction mechanisms was carried out, aiming to understand the influence of different functional groups on the studied isomerization processes.

Metisa plana (Lepidoptera: Psychidae), a foliar-feeding bagworm, is a major pest in oil palm plantations, particularly in Peninsular Malaysia. Government of Malaysia has classified it as a dangerous pest under the Plant Quarantine Act 1976. Effective and sustainable solutions remain elusive despite various management strategies, including chemical, cultural and biological methods.

A novel two-step fermentation process was developed to enhance mead flavor quality. Headspace Solid-Phase Microextraction Gas Chromatography-Mass Spectrometry (HS-SPME-GC-MS) with three columns was used to analyze the volatile profiles of meads, along with sensory evaluation and machine learning. Compared to traditional mead (TM), our novel mead (NM) reduced off-flavor compounds by 37.

Background: The gut is responsible for the digestion and absorption of nutrients, immune regulation, and barrier function. However, factors like poor diet, stress, and infection, can disrupt the balance of the gut microbiota and lead to intestinal inflammation and dysfunction.
Purpose: This systematic review aims to evaluate the effects of dietary plants-derived essential oil components on gut health and intestinal functions in animal models.

Background: and are Gram-positive bacteria involved in the development of dental caries, as they are able to form biofilms on tooth enamel, ferment sugars into acids, and survive under acidic conditions. This ultimately leads to a local lowering of the pH value on the tooth surface, which causes enamel cavities.
Hypothesis: One measure to reduce caries is to limit the growth of cariogenic bacteria by using two anti-bacterial agents with different mechanisms of action.
