Sulphur-containing amino acids, cysteine and methionine, are generally found in very low concentrations in grape-juice. The objective of this study was to identify the effects of methionine on aroma compounds formation. Nitrogen source effects on growth, fermentative behaviour and aroma

Two deletion mutants expected to be defective in nitrogen catabolite repression (NCR) were constructed in a commercial wine yeast background M2: a ure2 mutant and a dal80 gzf3 double mutant. Wild-type and both mutant strains were fermented in Sauvignon Blanc
Nitrogen deficiencies in grape musts are one of the main causes of stuck or sluggish wine fermentations. Currently, the most common method for dealing with nitrogen-deficient fermentations is adding supplementary nitrogen (usually ammonium phosphate). However, it is important to know

Organically-modified hydroxyapatite materials were synthesized through the addition of oxalic, succinic, adipic and citric acids to a calcium hydroxide solution before neutralization by ammonium dihydrogenphosphate. All carboxylic acids have a significant influence on apatite crystallinity and nanoparticle size, as indicated
The main hindrance in the use of polyhydroxyalkanoates (PHAs) as a replacement for existing petroleum-based plastics is their high production cost. The carbon source accounts for 50% of the cost for PHA production. Thus, increasing the yield and productivity of
