Combined effects of nutrients and temperature on the production of fermentative aromas by Saccharomyces cerevisiae during wine fermentation.

Appl. Microbiol. Biotechnol. 99(5) , 2291-304, (2015)

Volatile compounds produced by yeast during fermentation greatly influence the organoleptic qualities of wine. We developed a model to predict the combined effects of initial nitrogen and phytosterol ...

GC/MS method for determining carbon isotope enrichment and concentration of underivatized short-chain fatty acids by direct aqueous solution injection of biogas digester samples.

Talanta 143 , 56-63, (2015)

In anaerobic digestion of organic matter, several metabolic pathways are involved during the simultaneous production and consumption of short-chain fatty acids (SCFA) in general and acetate in particu...

Structural variation governs substrate specificity for organic anion transporter (OAT) homologs. Potential remote sensing by OAT family members.

J. Biol. Chem. 282 , 23841-53, (2007)

Organic anion transporters (OATs, SLC22) interact with a remarkably diverse array of endogenous and exogenous organic anions. However, little is known about the structural features that determine thei...
