应用


  • Changes in physicochemical properties and microbial community succession during leaf stacking fermentation.: This research investigates the changes in physicochemical properties and microbial communities during leaf fermentation, with a focus on the role of volatile compounds like 2,3-pentanedione. The study provides insights into fermentation processes and microbial interactions (Zhang et al., 2023).

The regulation of chemoreceptor (CR) gene expression by environmental signals and internal cues may contribute to the modulation of multiple physiological processes and behavior in Caenorhabditis elegans. We previously showed that KIN-29, a homolog of salt-inducible kinase, acts in sensory

During alcoholic fermentations, the off-flavour compound diacetyl is formed non-enzymatically from acetolactate leaking out from the cells. Acetolactate is an intermediate in the biosynthesis of valine. In beer fermentation, the amount of diacetyl is reduced to acceptable levels during maturation.

Addition of branched-chain amino acids (BCAA) or an inhibitor of the BCAA biochemical pathways during fermentation of milk with a lac(-) mutant of Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus strongly influenced the formation of two aroma-impact compounds, 2,3-butanedione and

Caenorhabditis elegans odr-2 mutants are defective in the ability to chemotax to odorants that are recognized by the two AWC olfactory neurons. Like many other olfactory mutants, they retain responses to high concentrations of AWC-sensed odors; we show here that
