The biosynthesis of L-carnitine in eukaryotic organisms was first elucidated in the ascomycete Neurospora crassa. The first step of the pathway is catalysed by ε-N-trimethyllysine hydroxylase (TMLH), which converts ...

Lipomyces kononenkoae secretes a battery of highly effective amylases (i.e. α-amylase, glucoamylase, isoamylase and cyclomaltodextrin glucanotransferase activities) and is therefore considered as one of the most efficient ...

Improved fermentation of starch and its dextrin products would benefit the brewing and whiskey industries. Most strains of Saccharomyces ferment glucose and maltose and partially ferment maltotriose, but are unable to ...

While unfermented grape must contains approximately equal amounts of the two hexoses glucose and fructose, wine producers worldwide often have to contend with high residual fructose levels (>2 gl-1) that may account for ...

A total of 61 S. cerevisiae strains, 60 of them isolated from wine ecosystems, were evaluated for the presence of the gene encoding endopolygalacturonase (PGU1) and for polygalacturonase (PG) activity. Nine strains lack ...

The recombinant xylose-utilizing Saccharomyces cerevisiae TMB 3399 was constructed by chromosomal integration of the genes encoding D-xylose reductase (XR), xylitol dehydrogenase (XDH), and xylulokinase (XK). S. cerevisiae ...

The stilbene resveratrol is a stress metabolite produced by Vitis vinifera grapevines during fungal infection, wounding or UV radiation. Resveratrol is synthesised particularly in the skins of grape berries and only trace ...

Aims: To improve a method for determining β-glucosidase activity and to apply it in yeasts isolated from wine ecosystems from 'La Mancha' region and to know its cellular location. Methods and Results: A total of 82 wine ...

The yeast Saccharomyces cerevisiae predominantly ferments glucose to ethanol at high external glucose concentrations, irrespective of the presence of oxygen. In contrast, at low external glucose concentrations and in the ...
