Applicazioni

3-Methyl-1-butanol was used as standard in GC-MS analysis of volatile compounds produced by Rhizobacteria and Spanish Honeys.

Azioni biochim/fisiol

3-Methyl-1-butanol is produced as a fusel alcohol in yeast fermentation. It is a naturally-produced fuel substitute that has advantages of acting as precursor for isoamyl acetate and replacement for gasoline.

Chemical and plant growth studies of Bacilli strains GB03 and IN937a revealed that the volatile components 2,3-butanediol and acetoin trigger plant growth promotion in Arabidopsis. Differences in growth promotion when cytokinin-signaling mutants are exposed to GB03 versus IN937a volatiles suggest

3-Methyl-1-butanol is a potential fuel additive or substitute. Previously this compound was identified in small quantities in yeast fermentation as one of the fusel alcohols. In this work, we engineered an Escherichia coli strain to produce 3-methyl-1-butanol from glucose via

Many compounds being considered as candidates for advanced biofuels are toxic to microorganisms. This introduces an undesirable trade-off when engineering metabolic pathways for biofuel production because the engineered microbes must balance production against survival. Cellular export systems, such as efflux

Anopheles gambiae sensu stricto is considered to be highly anthropophilic and volatiles of human origin provide essential cues during its host-seeking behaviour. A synthetic blend of three human-derived volatiles, ammonia, lactic acid and tetradecanoic acid, attracts A. gambiae. In addition

Differences in the production of bacterial metabolites with potential impact on fermented sausage flavour were found in meat simulation medium when comparing different strains of Staphylococcus xylosus and Staphylococcus carnosus as starter cultures. Overall, higher levels of 3-methyl-1-butanol and acetoin
