General description

Isobutyl alcohol is a water-soluble aliphatic alcohol that can be used as a flavoring agent. It has been identified as one of the aroma/flavor compounds produced by Saccharomyces cerevisiae during the semi-aerobic fermentation of grapes to form wine.

Application


  • Volatiles from nutritional fungal symbiont influence the attraction of Anisandrus maiche (Coleoptera: Curculionidae) to ethanol-baited traps.: This investigation revealed that volatiles emitted by fungal symbionts impact the attraction of Anisandrus maiche to ethanol-baited traps. The study suggests potential applications in pest management strategies by utilizing isobutanol and other volatiles (Tobin et al., 2024).

Synergistic microbial communities are ubiquitous in nature and exhibit appealing features, such as sophisticated metabolic capabilities and robustness. This has inspired fast-growing interest in engineering synthetic microbial consortia for biotechnology development. However, there are relatively few reports of their use
